There can be no doubt that before the time of Eratosthenes the ideas of the learned world on the subject of geography had assumed a more regular and systematic form. It appears indeed from repeated statements of Strabo that Eratosthenes made it the object of his special attention to a€?reform the map of the world,a€? as it had existed down to his time, and to reconstruct it upon more scientific principles. With regard to the fundamental idea of all geography - the position and figure of the earth - Eratosthenes adopted the views that were current among the astronomers of his day, which had been received almost without exception from the times of Aristotle (ca.
But Eratosthenes had the merit of making one valuable addition to the previously existing ideas upon this subject, by a more careful and successful measurement than had ever been previously attempted, of the magnitude of the earth, or circumference of the terrestrial globe. The method pursued by Eratosthenes was theoretically sound, and was in fact identical in principle with that which has been adopted by astronomers in modern day.
While still keeping to the geocentric views of the universe, Eratosthenes started from the assumption that the sun was so distant that for practical purposes one could consider its rays parallel anywhere on earth. The only theoretical error in this mode of calculation was in the assumption - which was inevitable in the days of Eratosthenes - that the earth was exactly spherical, instead of being as it really is, a slightly oblate spheroid, and that therefore a meridian great circle was equal to that of the equator. In the first place, it was assumed that Syene lay directly under the tropic, it being a well-known fact that at the summer solstice the sun could be seen from the bottom of a deep well, and that at the same time the gnomon cast no perceptible shadow. It is remarkable that while the terrestrial measurement was thus grossly inaccurate, the observation of latitude as deduced from the gnomon at Alexandria was a very fair approximation to the truth: a fiftieth part of a great circle being equivalent to an arc of 7A°12a€™, thus exceeding by about 7a€™ only the true interval between Alexandria and Syene, while falling short of that between Alexandria and the real Tropic by about 30a€™ or half a degree. It appears indeed almost certain that Eratosthenes himself was aware of the imperfection of his data, and regarded the result of his calculation only as an approximation to the truth. After all it must be admitted that the calculation of Eratosthenes, considering the disadvantages under which he labored, came surprisingly near the truth. Once the value of 252,000 stades was accepted, it was feasible also to work out the circumference of any parallel circle. Having thus laid the foundation of what has been called in modern times a€?geodesya€? - the determination of the figure and dimensions of the earth, considered in its entirety, as a part of the system of the universe, Eratosthenes next proceeded to consider that portion of it which was in his time geographically known, or supposed to be inhabited. In his Geographica Eratosthenes discussed the best method of drawing a map of the inhabited area of the earth as known. Therefore, as with earlier map construction, the length of the oikumene greatly exceeds the width, though by what proportion depends on how much of the northern, eastern and southern extremities were regarded as inhabited. As approximations to sizes and shapes of parts of the world, Eratosthenes first divided the inhabited world by a line stretching from the Pillars of Hercules [Straits of Gibraltar] to the Taurus Mountains and beyond, then subdivided each of these two sections into a number of irregular shapes, or sphragides, which literally meant a€?an official seala€™ and later was extended to represent a plot of land numbered by a government surveyor, then by extrapolation to a numbered area on a map. Eratosthenes undoubtedly conceived, in accordance with the prevalent belief in his day, that the Ocean was found immediately to the east of India, and that the Ganges flowed directly into it. From that point he supposed the coast to trend away towards the northwest, so as to surround the great unknown tracts of Scythia on the north, but sending in a deep inlet to the south, which formed the Caspian Sea.
His ideas of the geographical position and configuration of India were also in great measure erroneous. Physical geography, in the modern sense of the term, was still quite in its infancy in the days of Eratosthenes, and it cannot be said that he did much to impart to it a scientific character. Eratosthenes also adopted, and apparently developed at considerable length, an idea first suggested by the physical philosopher Strabo, that the Mediterranean and the Euxine [Black] Seas had originally no outlet, and stood in consequence at a much higher level, but that they had burst the barriers that confined them, and thus given rise to the Straits of the Bosphorus, the Hellespont and that of the columns. This map of the known world was a very striking achievement and may be considered to be the first really scientific Greek map.
DESCRIPTION: It was Martin Behaim of Nuremberg (1459-1507), who, in so far as we have knowledge, constructed one of the first modern terrestrial globes, and it may, indeed, be said of his a€?Erdapfel,a€? as he called it, that it is the oldest terrestrial globe extant. In the year 1490 he returned for a visit to his native city, Nuremberg, and there is reason for believing that on this occasion he was received with much honor by his fellow townsmen. The manufacture of a hollow globe or sphere can hardly have presented any difficulty at Nuremberg, where the traditions of the workshop of Johann MA?ller (Regiomontanus), who turned out celestial spheres, were still alive.
The mould or matrix of loam was prepared by a craftsman bearing the curious name of Glockengiesser, a bell-founder.
The important duty of transferring the map to the surface of the globe and illuminating it was entrusted to Glockenthon (and possibly Erhard Etzlaub).
For over a hundred years the globe stood in one of the upper reception rooms of the town hall, but in the beginning of the 16th century it was claimed by and surrendered to Baron Behaim. The globe, in its pristine condition, with its bright colors and numerous miniatures, must have delighted the eyes of a beholder.
At the request of the wise and venerable magistrates of the noble imperial city of Nuremberg, who govern it at present, namely, Gabriel Nutzel, P. The globe is crowded with over 1,100 place-names and numerous legends in black, red, gold, or silver. 1,431 years after the birth of our dear Lord, when there reigned in Portugal the Infant Don Pedro, the infant Don Henry, the King of Portugala€™s brother, had fitted out two vessels and found with all that was needed for two years, in order to find out what was beyond the St.
In the year 734 of Christ when the whole of Spain had been won by the heathen of Africa, the above island Antilia called Septa Citade [Seven Cities] was inhabited by an archbishop from Porto in Portugal, with six other bishops and other Christians, men and women, who had fled thither from Spain by ship, together with their cattle, belongings and goods.
Through the inspiration of Behaim the construction of globes in the city of Nuremberg became a new industry to which the art activities of the city greatly contributed.
The longitudinal extent of the old world accepted by Ptolemy was approximately 177 degrees to the eastern shore of the Magnus Sinus, plus an unspecified number of degrees for the remaining extent of China. The new knowledge displayed is confined to Africa, or rather to the western coast for the names on the east coast, save for those taken from Ptolemy, are fanciful.
Sources: Behaim informs us in one of the legends of his globe that his work is based upon Ptolemya€™s Cosmography, for the one part, and upon the travels of Marco Polo and Sir John Mandeville, and the explorations carried on by the order of King John of Portugal, for the remainder. Ptolemy (#119): Behaim has been guided by the opinion of the a€?orthodox a€? geographers of his time and has consequently copied the greater part of the outline of the map of the world designed by the great Alexandrian. Isidore of Seville (#205), or one of his numerous copyists, is the authority for placing the islands of Argyra, Chryse and Tylos far to the east, to the south of Zipangu [Japan]. Marco Polo: One cannot fail to be struck by the extent to which the author of the globe is indebted to the greatest among medieval travelers. A comparison of this sketch with Behaima€™s globe, or indeed with other maps of the period, even including SchA¶nera€™s globe of 1520 (#328), shows clearly that a much nearer approach to a correct representation to the actual countries of Eastern Asia could have been secured had these early cartographers taken the trouble to consult the account which Marco Polo gave of his travels. The only contemporary map upon which the delineation of Eastern Asia including the place names is almost identical with that given on Behaima€™s globe is by Martin WaldseemA?ller (#310), and was published in 1507. According to Marco Poloa€™s records, the longitudinal extent of the Old World, from Lisbon to the east coast of China, is approximately 142A°.
Paolo Tosconelli in 1474 (#252), on the other hand, gives the old world a longitudinal extension of 230A° thus narrowing the width of the Atlantic to 130A°.
Toscanelli may be deserving of credit, for having been the first to draw a graduated map of the great Western Ocean, but when we find that he rejected Ptolemya€™s critique of the exaggerated extent given by Marinus of Tyre to the route followed by the caravans in their visits to Sera, and failed to identify Ptolemya€™s Serica with the Cathaia of Marco Polo, as had been done before him by Fra Mauro, we are not able to rank him as high as a critical cartographer as he undoubtedly ranks as an astronomer.
Sir John Mandeville: Jean de Bourgogne, a learned physician of Liege, declared on his death-bed (in 1475) that his real name was Jean de Mandeville, but that having killed a nobleman he had been obliged to flee England, his native country, and live in concealment. Portolano Charts (#251): These nautical [sailing direction] charts were widely distributed in Behaima€™s time, and the fact that the Baltic Sea (Ptolemya€™s Mare Germanicum) appears on the globe as Das mer von alemagna, instead of Das teutsche Mer, is proof conclusive that one of these popular charts was consulted when designing the globe or preparing the map which served for its prototype. But while improving Ptolemya€™s northern Europe with the aid of a portolano chart, he blindly followed the Greek cartographer in his delineation of the contours of the Mediterranean, and this notwithstanding the fact that the superiority of these portolano charts had not only long since been recognized by all seamen who had them in daily use, but also by the compilers of a number of famous maps of the world, including the Catalan Atlas of 1375 (#235), which the King of Aragon presented to Charles V. Portuguese Sources: When Behaim, in the spring of 1490, left Lisbon for his native Nuremberg, Bartolomeu Diaz had been back from his famous voyage round the Cape for over twelve months, numerous commercial and scientific expeditions had improved the rough surveys made by the first explorers along the Guinea coast, factories had been established at Arguim, S. There is no doubt that the early Portuguese navigators brought home excellent charts of their voyages. Behaim, of course, enjoyed many opportunities for examining the charts brought home by seamen not only, but also other curious maps, whose existence has been recorded although the maps themselves have long since disappeared. In addition to maps and charts a person of Behaima€™s social position and connections might readily have had access to the reports of contemporary explorers. Miscellaneous Sources: Foremost amongst these rank the maps in the Ulm edition of Ptolemy (1482), of which Domunus Nicolaus, a German residing in Italy, was the author. Bartolomeo of Florence, who is said to have traveled for 24 years in the East (1401-1424), but whose name and reputation are other vise unknown, is quoted at length on the spice trade. Behaim had access, likewise, to valuable collections of books and maps, most important among which was the library of the famous Johann MA?ller of KA¶nigsberg (Monteregio), who at the time of his death was engaged upon a revised edition of Ptolemy, which he intended to illustrate with modern maps, including one of the entire world. But long before WaldseemA?ller and Behaim, the same old map must have been accessible to Dom. Be it known that on this Apple [Globe] here present is laid out the whole world according to its length and breadth in accordance with the art geometry, namely, the one part as described by Ptolemy in his book called Cosmographia Ptolemaei and the remainder from what the Knight Marco Polo of Venice caused to be written down in 1250. The ocean on Behaima€™s globe surrounds the continental mass of land, though covered around the North Pole with many large islands, so that in order to proceed from Iceland direct to the north coast of Asia it is necessary to pass through a narrow strait.
The North Sea, the Oceanus Germanicus of Ptolemy, is described as das engelis mere [the English Sea], for by that name it was known to the sailors of Scandinavia and of northern Germany. Be it known that the sea called Ocean, between the Cape Verde Islands and the mainland, runs swiftly to the south; when Hercules had arrived here with his ships and saw the declivity (current) of the sea he turned back, and set up a column, the inscription upon which proves that Hercules got no further. The Pillars of Hercules originally stood on the island of Gades [Cadiz], outside the Straits of Gibraltar, but in proportion as geographical knowledge extended so were these columns pushed ahead. On a Catalan-Estense map of 1450 (#246), there are two small islands off Cape Verde described as Illa de cades: asi posa ercules does colones [Cades Island where Hercules set up two columns], and on Fra Mauroa€™s famous map of 1459 (#249) a legend to the south of Cabo rosso tells us that he had heard from many that a column stood there with an inscription stating that it was impossible to navigate beyond. Diogo Gomez, an old mariner, well known to Behaim, to whom he presented his account De prima inventione Guineae, tells us that JoA?o de Castro, on his homeward voyage in 1415, had to struggle against the current which swept round Cabo de Non, upon which Hercules had set up a column with the well-known legend, quis navigat ultra caput de Non revertetur aut non. Gregory of Nyssa (died 395) already knew of the existence of this current, which he ascribed to the excessive evaporation caused by the great heat of the southern sun and the absence of evaporation in the cool north. Behaima€™s Sinus arabicus corresponds to our Gulf of Aden, and this gulf as well as the das rod mer [the Red Sea], is, of course, colored red.
Iceland: The story of the Icelanders selling their dogs and giving away their children is a fable invented by English and Hanseatic pirates and merchants, who kidnapped children, and even adults, and sold them into slavery. Item, in Iceland are to be found men eighty years of age who have never eaten bread, for corn does not grow there, and instead of bread they eat dried fish.
Insula de Brazil: The imaginary Jnfula de prazil, to the west of Ireland, appears for the first time on Dulcerta€™s chart (1339). Antilia: An imaginary island of Antilia (also spelled, Antillia ) has found a place upon the charts since the 14th century and was at an early date identified by the Portuguese with the equally imaginary Ilha de sete cidades [the island of the seven cities] where the Archbishop of Oporto with his six bishops is imagined to have fled after the final defeat of King Roderick of the Visigoths on the Guadalete in 711 and the capture of Merida in 712 by the Arabs. The historian Galvao (1862) reports that in 1447 a Portuguese vessel, driven westward by a storm, actually arrived at the island, the inhabitants of which still spoke the Portuguese tongue; other voyages to this island in the time of Prince Henry are referred to in the Historie of Fernand Colombo.
Antilia on the ancient maps is a huge island, quadrangular in shape, resembling in all respects the Zipangu of Behaima€™s globe.
In the year 734 of Christ, when the whole of Spain had been won by the heathen [Moors] of Africa, the above island Antilia, called Septe citade [Seven cities], was inhabited by an archbishop from Porto in Portugal, with six other bishops, and other Christians, men and women, who had fled thither from Spain, by ship, together with their cattle, belongings and goods. Scandinavia: This area is almost wholly copied from a map in the Ulm edition of Ptolemy published in 1482. Marco Polo in the 38th chapter of the third book states that the mariners had verily found in this Indian Ocean more than 12,700 inhabited islands, many of which yield precious stones, pearls and mountains of gold, whilst others abound in twelve kinds of spices and curious peoples, concerning whom much might be written.
There he shall find accounts of the curious inhabitants, of the islands, the monsters of the ocean, the peculiar animals on the land and of the islands yielding spices and precious stones. Many noble things are said about this island in ancient histories, how they (the inhabitants) helped Alexander the Great and went with the Romans to Rome in the company of the Emperor Pompey. The island Seilan, one of the best islands in the world, but it has lost in extent to the seas.
Item, in past times the great Emperor of Cathay sent an ambassador to this King of Seilan, asking for this ruby and offering to give much treasure for it. The Three Holy Kings and Prester John: The three a€?holy kings a€? whose bones are exhibited to credulous visitors at Cologne Cathedral and whose memory is revived annually on Twelfth Day, were undoubtedly the King of Tarshish and the Isles, and the Kings of Sheba and Saba, of Psalm xxii. Closely connected with the legend of the Three Kings is the reported existence of a powerful Christian Prince, Presbyter or Prester John, in the center of Asia. The Tarshish of the Psalmist must be sought in the East, in maritime India, and not at Tartessus in the West; Sheba was in Southern Arabia, and Saba on the authority of Marco Polo probably in Persia. On Behaima€™s globe the Three Kings are localized in Inner Asia, on the Indian Ocean and in East Africa (Saba). On this mountain, the Mons victorialis (called Mount Gybeit by John of Marignola) the Three Kings watched for the appearance of the star which, according to Balaama€™s prophecy (Numbers xxiv. Below this we read Saba, which clearly stands for Shoa or Shewa, and to the west is a picture of this Prester John of Abassia with a kneeling figure in front of him. In this country resides the mighty Emperor known as Master John, who is appointed governor of the three holy kings Caspar, Balthazar and Melchior in the land of the Moors. Og to the west and Magog to the south of Tenduk are described by Marco Polo as being subject to the Prester. The country towards midnight is ruled by the Emperor Mangu, khan of Tartary, who is a wealthy man of the great Emperor, the Master John of India, the wife of the great King is likewise a Christian.
All this land, sea and islands, countries and kings were given by the Three Holy Kings to the Emperor Presbyter John, and formerly they were all Christians, but at present not even 72 Christians are known to be among them. Mandeville, says that 72 provinces and kings were tributaries of Prester John, on the authority of an apocryphal letter supposed to have been sent to Manuel Commenus (1143-80), the Pope and others.
Zipangu is the most noble and richest island in the east, full of spices and precious stones. Conclusion: Behaim is no doubt indebted to his globe, and to the survival of that globe, for the great reputation that he enjoys among posterity. But we may well ask whether greatness was not in a large measure thrust upon Behaim by injudicious panegyrists; and if, on a closer examination of his work, he does not quite come up to our expectations, they, at all events, must bear the greater part of the blame. Maximilian, invincible King of the Romans, who, through his mother, is himself a Portuguese, intended to invite Your Majesty through my simple letter to search for the eastern coast of the very rich Cathay . Before embarking upon his journey, Magellan himself stated he knew that south of America there was a sound that led to the Southern Sea which Balboa had discovered in I5I3 at the Isthmus of Panama: he, Magellan, had seen the sound on a map by Martin Behaim. No one has yet determined what connection the work of the Nuremberg scholar Behaim has with Magellana€™s great achievement.
Martin Behaim has accordingly been repeatedly regarded in former times as the actual discoverer of the Magellan Straits and even of the whole of America. Later, in I786, Otto, a German who then resided in the United States, described Behaim as the actual discoverer of America. An outright struggle has been conducted for centuries concerning Behaima€™s claim to priority in the discovery of America (he himself had not the least idea of this strife).
This certainly does not do away with Magellana€™s peculiar statement that he already had seen on a map the straits which he set out to sail along.
Magellana€™s conduct before his departure is depicted in greater detail in 1601 by the Spanish chronicler Herrera who, as Humboldt supposed, could use the notes made by Andrea de San Martin, the astronomer of the Magellan expedition. This report can certainly be assumed to be true, with the exception of Behaima€™s authorship. Two years later the same SchA¶ner made a globe (Book IV, #328) which in a charming manner enriched the Behaim, globe of 1492 with the new discoveries in the western ocean.
The definite assertions in the pamphlet of 1508, of Johann SchA¶ner and others, that at their time the Portuguese had already discovered a sound south of America were certainly bona fide but are nevertheless incredible. That Magellana€™s a€?advance knowledgea€? of the straits which he was to discover was doubtful is also indicated by a notice made by Pigafetta to the effect that in the austral winter of 1520 the explorer wintered with his crew on the coast on 49A° 8' S. Thus one can today describe as well-established facts that the Magellan Straits are rightly called so, that prior to the Portuguese discoverer the hypotheses connected with Martin Behaima€™s name must be considered figments of imagination. Breusing, Zur Geschichte der Geographie, Regiomontanus, Martin Behaim und der Jacobstab, Zeitsch, der Gesellsch. Humboldt, Examen Critique de la€™Histoire de la Geographie du Nouveau Continent et des progres de la€™astronomie nautique dans les XVe et XVIe siecles, volume 1, pp. Detail of the Atlantic Ocean, Zipangu [Japan} on the left, real and mythical islands such as Antilia and St.
The compilation of a printed mappamundi, which was used for the globe, naturally fell to the share of Behaim himself. The globe is crowded with over 1,100 place-names and numerous legends in black, red, gold, or silver.A  The legends, in the south German dialect of the period, are very numerous, and are of great interest to students of history and of historical geography. More symmetrical than accurate, its partitions were the forerunners of parallels and meridians after DicA¦archus (#111).
And it is certain also that these had been embodied in the form of maps, which, however imperfect, were unquestionably very superior to anything that had preceded them. It is this enlarged and philosophical view of the subject that constitutes his special merit, and entitles him to be justly called as the a€?parent of scientific geographya€?. Once the idea of a spherical earth was accepted, and that it was a perfect sphere, the measurement of this body was a logical step, even to Greek scholars who were more given to philosophical speculation than to quantification and experimentation. The method pursued by Eratosthenes is fully stated and explained by the astronomer Cleomedes, in his work on the Circular Motion of the Heavenly Bodies.
He observed that the rays of the sun, at midday, at the time of the summer solstice, fell directly over Syene [modern-day Aswan] and that the vertical rod of the sun dial (gnomon or style) would not cast a shadow (predicated on the assumption that Syene was situated exactly under the Tropic of Cancer).
But, though these facts were perfectly correct as matters of rough observation, such as could be made by general travelers, they were far from having the precise accuracy requisite as the basis of scientific calculations.
Hence, as mentioned above, he felt himself at liberty to add 2,000 stades to the 250,000 obtained by his process, in order to have a number that would be readily divisible into sixty parts, or into degrees of 360 to a great circle. His measurement of 250,000 stades (the immediate result of his calculation) would be equivalent to 25,000 geographical miles, while the actual circumference of the earth at the equator falls very little short of 25,000 English miles. Thus Eratosthenes calculated that the parallel at Rhodes, 36A°N., was under 200,000 stades in circumference.
And here it must be observed that the relation between the habitable world, which was alone regarded as coming within the scope of the geographer (properly so called), and the terrestrial globe itself, was, in the days of Eratosthenes, and even long afterwards, a very different one from that which we now conceive as subsisting between them. The first task of the geographer therefore, according to the notions then prevailing, was to determine the limits and dimensions of the map of the world, which was to form the subject of his special investigations. India he suggested drawing as a rhomboid; Ariana [the eastern part of the Persian Empire] would be illustrated as approximating a parallelogram. Just to the north of the Ganges the great mountain chain of Imaus, which he regarded as the continuation of the Indian Caucasus and the Taurus, descended (according to his ideas) to the shores of the Eastern Ocean; and he appears to have given the name of Tarnarus to the headland which formed the termination of this great range. Of the northern shores of Asia or Europe he had really no more knowledge than Herodotus (#109), but, unlike that historian, he assumed the fact that both continents were bounded by the Ocean on the north; a fact which is undoubtedly true, but in a sense so widely different from that supposed by Eratosthenes that a can hardly be held as justifying his theory. As mentioned above, he conceived it to be of a rhomboidal form, which may be regarded as a rough approximation to the truth, and he even knew that the two sides, which enclosed the southern extremity, were longer than the other two. In treating the mountain chains of Asia as one continuous range, to which he applied the name of Taurus, he may be regarded as having made a first attempt, however crude, at that systematic description of mountain ranges to which we now give the name of orography.
In proof of this theory he alleged the presence of marine shells far inland in Libya, especially near the temple of Jupiter Ammon, and on the road leading to it, as well as the deposits and springs of salt that were also found in the Libyan deserts.
Although the dimensions are not known exactly, as it was presented to the Egyptian court a may be assumed to have been fairly large.

He took advantage of the opportunities which were offered him for travel, though, according to both E.G.
It was the suggestion of George Holzschuher, member of the City Council, and himself somewhat famed as a traveler, that eventually brought special renown to this globe maker, for he it was who proposed to his colleagues of the Council that Martin Behaim should be requested to undertake the construction of a globe on which the recent Portuguese and other discoveries should be represented. This map was subsequently mounted upon two panels, framed and varnished and hung up in the clerka€™s office of the town hall.
This was fortunate, for had it remained, uncared for, in the town hall it might have shared the fate of so many other a€?monumentsa€? of geographical interest, the loss of which the living generation has been fated to deplore.
In the course of time, however, the once brilliant colors darkened or faded, parts of the surface were rubbed off; many of the names became illegible or disappeared altogether. Volkhamer, and Nicholas Groland, this globe was devised and executed according to the discoveries and indications of the Knight Martin Behaim, who is well versed in the art of cosmography, and has navigated around one-third of the earth. The chief magistrate induced his fellow citizen to give instruction in the art of making such instruments, yet this seems to have lasted but a short time, for we learn that not long after the completion of his now famous Erdapfel, Behaim returned to Portugal, where he died in the year 1507. The globe has also great importance in the perennial controversy over the initiation of Columbusa€™ great design and the subsequent evolution of his ideas on the nature of his discoveries. Ravenstein has shown that Behaim possibly made a voyage to Guinea in 1484-5, but that he was certainly not an explorer of the southern seas and a possible rival of Columbus, and his cartographical attainments were distinctly limited. Behaim accepted more or less Ptolemya€™s 177A° and added 57A° to embrace the eastern shores of China.
We are justified in assuming on these and other grounds that Behaim had not gone directly to the authorities he quotes, but had merely amended an existing world map. The main features of the west coast are more or less recognizable, though Cape Verde is greatly over-emphasized. Other sources were, however, drawn upon by the compiler, and several of these are incidentally referred to by him or easily discoverable, but as to a considerable part of his design scholars have been unable to trace the authorities consulted by him. He has, however, rejected the theory of the Indian Ocean being a mare clausum [closed sea] and although he accepted Ptolemya€™s outline for the Mediterranean, the Black Sea and the Caspian, he substituted modern place names for most of those given by ancient geographers. Accounts, in manuscript, of Poloa€™s travels in Latin, French, Italian and German, were available at the time the globe was being made at Nuremberg, as well as three printed editions. One may conclude from this that both Behaim and WaldseemA?ller derived their information from the same source, unless, indeed, we are to suppose that the Lotharingian cartographer had procured a copy of the globe that he embodied in his own design. This encouraged Columbus to sail to the west in the confident hope of being able to reach the wealthy cities of Zipangu and Cathay. He may have been the a€?initiatora€? of the voyage that resulted in the discovery of America, but cannot be credited with being the a€?hypotheticala€? discoverer of this new world.
Further evidence of such use is afforded by the outline given to the British Isles, and possibly also by a few place names in western Africa, which are Italian rather than German or Portuguese. Jorge da Mina, Benin and, far within the Sahara, at Wadan, trading expeditions had gone up the Senegal and Gambia, and relations established with Timbuktu, Melli and other states in the interior.
Columbus, who saw the charts prepared by Bartolomeu Diaz, speaks of them as a€?depicting and describing from league to league the track followeda€? by the explorer. He might have learned much from personal intercourse with seamen and merchants who had recently visited the newly discovered regions or were interested in them.
Behaima€™s laudable reticence as to mirabilia mundi has been referred to already, but he does not disdain to introduce long accounts concerning the a€?romancea€? of Alexander the Great, the myth of the a€?Three Wise Mena€? or kings, the legends connected with Christian Saints, such as St.
Nicolaus Germanus, for in the map of the world in the edition of Ptolemy published in 1482 he introduces a third head stream of the Nile, which is evidently derived from it. The worthy Doctor and Knight Johann de Mandavilla likewise left a book in 1322 which brought to the light of day the countries of the East, unknown to Ptolemy, whence we receive spices, pearls and precious stones, and the Serene King John of Portugal has caused to be visited in his vessels that part to the south not yet known to Ptolemy in the year 1485, whereby I, according to whose indications this Apple has been made, was present. The Arctic Ocean, called das gesrore mer septentrionel [the frozen sea of the North] is surrounded on all sides by land. The Baltic, the Mare Germanicum of the learned, is called das mer von alemagna, [the German Sea], which proves conclusively, according to Ravenstein, that Behaim in delineating that part of the world was guided by an Italian or Catalan portolano chart. Albertus Magnus (died 1280) in his Meteorologia ascribed the current to the same cause, namely, a difference in the level of the ocean due to differences of evaporation, but believed the current thus produced to be steady and almost imperceptible.
As an instance may be mentioned the misdeeds of William Byggeman, the captain of the a€?Trinity,a€™ who was prosecuted in England in 1445, for having committed this offense.
It is the custom there to sell dogs at a high price, but to give away the children to (foreign) merchants, for the sake of God, so that those remaining may have bread. Subsequently, in the Medicean Portolano Chart of 1351 (#233), it figures as one of the Azores, usually identified with Terceira, a cape of which still bears the name of Morro do Brazil.
Two flags fly above these islands from the same flagstaff, the upper one with the arms of Nuremberg, the lower with those of Behaim. These voyages, however, are purely imaginary, or, at all events, led to no actual discoveries.
Brandon in his ship came to this island where he witnessed many marvels, and seven years afterwards he returned to his country. The author of the globe was well aware that the three northern kingdoms, since the Union of Calmar (1397), were ruled by the King of Denmark, for the standard of that kingdom flies at the mouth of the Elbe, at the westernmost point of Norway and on Iceland. And if anyone desires to know more of these curious people, and peculiar fish in the sea or animals upon the land, let him read the books of Pliny, Isidore (of Seville), Aristotle, Strabo, the Specula of Vincent (of Beauvais) and many others. This island has a circuit of 4,000 miles, and is divided into four kingdoms, in which is found much gold and also pepper, camphor, aloe wood and also gold sand.
But the King replied that this stone had for a long time belonged to his ancestors, and it would ill become him to send this stone out of the country. It was not doubted that these a€?kingsa€? were descended from the three wise men from the East, who, according to Matthew ii. This rumor first reached Europe through the Bishop of Gabala in 1145, and it was supposed that this Royal Priest was a direct successor or descendant of the Three Kings. Saba Ethiopie, however, in course of time, was transferred to Abyssinia, and its Christian ruler was accepted as the veritable and most popular Prester John. Here is a royal tent with the following legend: The kingdom of one of the Three Holy Kings, him of Saba. But while the undoubted beauties of that globe are due to the miniature painter Glockenthon, according to Ravenstein the purely geographical features do not exhibit Behaim as an expert cartographer, if judged by modern standards. The globe by Behaim was designed to demonstrate the ease with which one could sail westward to Japan and China, to the Zipangu and Cathay of Marco Polo.
Unknown to Behaim, Columbus had discovered the Bahamas and the Antilles and had returned to Spain by March 1493.
Otto's arguments seemed so convincing that Benjamin Franklin had a letter which Otto had written him printed in the works of the Philosophical Society of Philadelphia.
Postela€™s Cosmography speaks outright of Martini Bohemi fretum and in 1682 Wagenseil demanded that the Magellan Straits be called the Behaim Straits. The following took place according to Herrera: a€?(When Magellan) appeared for the first time at the Spanish court in Valladolid, he showed the Bishop of Burgos a painted globe on which he had traced his planned route. 12 years prior to Magellana€™s discovery, there was printed a pamphlet which spoke of the circumnavigability in the south of the newly discovered south American country.
The whole of South America - as much as was discovered of it by that time - appears on this globe under the name of Paria sive Brasilia, south of it the sea rises in a broad front against the continent. If Magellan had ever come across it, he would, as can be understood, have believed that Behaim was its author. However, due to the verities of time, many legends and place-names are illegible.A  In his book on the life and work of Behaim, Ravenstein provides a complete listing of all decipherable place-names and legends, along with a translation and discussion where his interpretation differs from previous scholars.
Geographic information that was gathered by Alexander the Great and his successors was the primary source used by Eratosthenes, a scholar with vision large enough to put this information into a logical framework.
The first use of world maps by the Greeks had been introduced at a very early period by Anaximander (ca. The materials at his command were still very imperfect, and the means of scientific observation were wanting to a degree which we can, at the present-day, scarcely figure to ourselves; but the methods which he pursued were of a strictly scientific character, and his judgment was so sound that he proved in many instances to be better informed and more judicious in his inferences than geographers of two centuries later.
He was not indeed the first who had attempted the solution of this problem, which would naturally engage the attention of astronomers and geometers, as soon as it was agreed that the earth was of a spherical form. Both the method and the accuracy of Eratosthenesa€™ well-known measurement of the earth have evoked the admiration of later workers, and his calculation is regarded as one of the greatest achievements of Greek science. Syene is in fact situated in latitude 24A° 5a€™ 30a€?, or nearly 37 miles to the north of the Tropic.
Ever since the discoveries of the great Portuguese and Spanish navigators in the 15th and 16th centuries opened out to us new continents, and extensions of those already known, far beyond anything that had previously been suspected or imagined, men have been accustomed to regard the a€?map of the worlda€? as comprising the whole surface of the globe, and including both the eastern and western hemispheres, while towards the north and south it is capable of indefinite extension, until it should reach the poles, and is in fact continually receiving fresh accessions.
This question, which was taken up by Eratosthenes at the beginning of his second book, had already been considered by several previous writers, who had arrived at very different results. Rather than a rectangle, he thought of the oikumene as tapering off at each end of its length, like a chlamys [short Greek mantle]. In fact the conclusion of Eratosthenes was mainly based upon the erroneous belief that the Caspian communicated with the Ocean to the north in the same manner that the Persian Gulf did to the south; a view which was adopted by all geographers for a period of three centuries, on the authority of Patrocles.
Yet the erroneous idea of its communication with the Ocean to the north sufficiently shows how questionable the information possessed by the Greeks really was. But as he supposed the range of Imaus that bounded the country to the north to have its direction from west to east, while the Indus flowed from north to south, he was obliged to shift around the position of his rhomb, so as to bring the other two sides approximately parallel to the two thus assumed.
He also arrived at a sound conclusion concerning the causes of the inundation of the Nile, a subject that must naturally have engaged the attention of a geographer resident in Egypt.
It must have been drawn as closely as possible to scale, and its influence on subsequent Greek and Roman cartography was tremendous.
From a record on the globe itself, placed within the Antarctic Circle, we learn that the work was undertaken on the authority of three distinguished citizens, Gabriel Nutzel, Paul Volckamer, and Nikolaus Groland.
Johann SchA¶ner, in 1532, was paid A?5 for a€?renovatinga€? this map and for compiling a new one, recording the discoveries that had been made since the days of Behaim. Having covered the mould with successive layers of paper, pasted together so as to form pasteboard, he cut the shell into two hemispheres along the line of the intended Equator. The mechanician Karl Bauer, who, aided by his son Johann Bernhard, repaired the globe in 1823, declared to Ghillany, that it had become very friable (mA?rbe), and that he found it difficult to keep it from falling into pieces. The whole was borrowed with great care from the works of Ptolemy, Pliny, Strabo, and Marco Polo, and brought together, both lands and seas, according to their configuration and position, in conformity with the order given by the aforesaid magistrates to George Holzschuer, who participated in the making of this globe, in 1492. Ravenstein describes this remarkable cartographic monument of a period that represented the beginning of a rapid expansion of geographical knowledge (in summary): Martin Behaima€™s map of the world was drawn on parchment that had been pasted over a large sphere.
The ships thus provisioned sailed continuously to the westward for 500 German miles, and in the end they sighted these ten islands. All the available evidence tends to show that he was a successful man of business who made a certain position for himself in Portugal, and who, like many others of his time, was keenly interested in the new discoveries. No special knowledge of Contia€™s narrative is shown, but a certain Bartolomeo Fiorentino, not otherwise known, is quoted on the spice trade routes to Europe. To Cape Formoso, on the Guinea coast the nomenclature differs little from contemporary usage.
The edition of Ptolemy of which he availed himself was that published at Ulm in 1482, and reprinted in 1486, with the maps of Dominus Nicolaus Germanus. Sri Lanka though unduly magnified would have occupied its correct position, and the huge peninsula beyond Ptolemya€™s a€?Furthest,a€? a duplicated or bogus India, would have disappeared, and place names in that peninsula, and even beyond it, such as Murfuli, Maabar, Lac or Lar, Cael, Var, Coulam, Cumari, Dely, Cambaia, Servenath, Chesmakoran and Bangala would have occupied approximately correct sites in Poloa€™s India maior. A comparison of the two shows, however, that such cannot have been the case, for there are many names upon the map that are not to be found on the globe. The author of the Laon globe went even further, for he reduced the width of the Atlantic to 110A°. That honor, if honor it be, in the absence of scientific arguments is due to Crates of Mallos (#113), who died 145 years before Christ, whose Perioeci and Antipodes are assigned vast continents in the Western Hemisphere, or to Strabo (66 B.C. Behaim, however, erred in good company, and for years after the completion of his globe the mistaken views of Ptolemy respecting the longitudinal extent of the Mediterranean were upheld by men of such authority as WaldseemA?ller (1507), SchA¶ner (1520), Gerhard Mercator (1538), and Jacobus Gastaldo (1548).
In addition to all this, ever since the days of Prince Henry and the capture of Ceuta, in 1417, information on the interior had been collected on the spot or from natives who were brought to Lisbon to be converted to the Christian faith.
But not one of these original charts has survived, and had it not been for copies made of them by Italians and others, our knowledge of these early explorations would have been even less perfect than it actually is. Fernando, the son of King Manuel, in 1528, and which had been brought to the famous monastery of Alcoba, ca. His contemporary, the printer, Valentin Ferdinand, was thus enabled not only to consult the manuscript Chronicle of Azurara, and the records of Cadamosto (credited with the discovery of the Azores) and Pedro de Cintra (his account of a voyage to Guinea), but also to gather much valuable information from Portuguese travelers who had visited Guinea.
There are three sections of the globe, upon the origins of which much light might be thrown by the discovery of ancient maps formerly in the possession of John MA?ller. Towards the west the Sea Ocean has likewise been navigated further than what is described by Ptolemy and beyond the Columns of Hercules as far as the islands Faial and Pico of the Azoreas occupied by the noble and valiant Knight Jobst de HA?rter of Moerkerken, and the people of Flanders whom he conducted thither.
It is the Mare concretum of Pierre da€™Aillya€™s Imago mundi, and of the Ulm edition of Ptolemy printed in 1482. Later charts, like that of Pizzigani (1367), contained three islands of the name, the one furthest north lying to the west of Ireland.
We are told nothing about the a€?burning mountaina€? and the great earthquake which happened in 1444. Two more flags are merely shown in outline and may have been intended for the arms of Portugal and Hurter.
It is certain, however, that FernA?o Telles, in 1475, and FernA?o Dulmo, in 1486, were authorized to sail in search of this imaginary island.
Brandan, who, after a seven yearsa€™ peregrination over a sea of darkness, penetrated to an Island of Saints, a terra repromissionis sanctorum, was very popular during the Middle Ages.
The ruby is said to be a foot and a half in length and a span broad, and without any blemish.
1-10, were guided by a star to Bethlehem, and there worshipped the newborn a€?King of the Jews.a€? The Venerable Bede (died 735) already knew that the names of these kings were Caspar, Melchior and Balthasar. Friar John of Marignola (1338-53) is the first traveler who mentions an a€?African archpriest,a€? and on a map of the world that Cardinal Guillaume Filastre presented in 1417 to the library of Reims we read Ynde Pbr Jo at the easternmost cape of Africa. 8), but Polo says that they are known to the natives as Ung and Mongul, that is, the Un-gut, a Turkish tribe, and the Mongols. The above information as well as that given in the remaining legends may have been taken from Mandeville, who himself is indebted to Haiton, Friar Odorico and others.
He was not a careful compiler, who first of all plotted the routes of the travelers to whose accounts he had access, and then combined the results with judgment. It showed Zipangu as only 80 degrees to the west of the Canaries and Cathay some 35 degrees more.
It sets a problem: two men with identical plans to reach Asia, at the same time in history and with similar cosmographical concepts.
The map has either been lost or, as already assumed by Humboldt, there was a mistake on the part of the Portuguese discoverer. It cannot be proved that Behaim had under-taken any longer sea-journey to the west from Fayal (Azores) where he mostly resided from 1486 to I507 with some intervals. As late as 1859 Ziegler and in 1873 the American Mytton Maury designated Behaim as Americaa€™s actual discoverer. However, it is altogether possible that Magellan had come across a map with the entry in question, as such maps have actually existed! The supplementary text - Magistralis - indicates however that it is a question of straits whose length and width cannot as yet be stated. It can be inferred that Magellan had no clear idea on which latitude the longed for sea route was to be found. The mechanician Karl Bauer, who, aided by his son Johann Bernhard, repaired the globe in 1823, declared to Ghillany, that it had become very friable (mA?rbe), and that he found it difficult to keep it from falling into pieces.A  In his opinion it could not last much longer. He regarded the earth as a sphere, placed in the center of the universe, around which the celestial sphere revolved every twenty-four hours: besides which, the sun and moon had independent motions of their own. Aristotle refers to the calculation of a€?mathematiciansa€? who had investigated the subject (without naming them) that the earth was 400,000 stades in circumference.
Secondly, Alexandria, instead of being exactly on the same meridian with Syene, lay in fact not less than three degrees of longitude to the west of it: an error of no trifling moment when the distance between the two was assumed as the basis of calculation. Thus was established the basis of a fairly accurate system of coordinates for any sectional mapping of the Mediterranean based upon the Rhodes parallel.
With the Greek geographers on the contrary, from Eratosthenes to Strabo, the known or habitable world was conceived as a definite and limited portion of the eartha€™s surface, situated wholly within the northern hemisphere, and comprised within about a third of the extent of that section. On one point indeed they were all agreed, that the length of the habitable world, from west to east, greatly exceeded as breadth, from north to south. Moreover, Strabo tells us that to the above total of 74,000 stades Eratosthenes, using another mathematical ploy, added 2,000 at each end, to prevent the width being more than half the length.
Hence he conceived the projecting angle of India to have a direction towards the southeast instead of the south, and even supposed it to advance farther towards the east than the mouth of the Ganges. On the other hand he stated a strange hypothesis: that the surplus waters of the Euphrates were carried by subterranean channels to Coele, Syria, and thence again underground so as to feed the streams which broke out near Rhinocorura and Mount Casius. Indeed, with Ptolemya€™s inaccurate alterations to the overall dimensions of the world and the oikumene, it can be said to have affected world maps right down to the Age of Discovery. Stevenson, it is hardly probable that he is entitled to that renown as an African coast explorer with which certain of his biographers have attempted to crown him, nor does it appear that he is entitled to a very prominent place among the men famed in his day for their astronomical and nautical knowledge.
The hemispheres were then taken off the mould, and the interior having been given stability by a skeleton of wooden hoops, they were again glued together so as to revolve on an iron axis, the ends of which passed through the two poles. It was left by the said gentleman, Martin Behaim, to the city of Nuremberg, as a recollection and homage on his part, before returning to meet his wife (Johanna de Macedo, daughter of Job de Huerter, whom he married in 1486) who lives on an island (at Fayal) seven hundred leagues from this place, and where he has his home, and intends to end his days. The globe itself has a circumference of 1,595 mm, consequently a diameter of 507 mm or 20 inches, resulting in a scale of 1:25,138,000.
On landing they found nothing but a wilderness and birds that were so tame that they fled from no one. The effect of this was to reduce the distance from Western Europe westwards to the Asiatic shores to 126A°, in place of the correct figure of 229A°. Southeast Asia is represented as a long peninsula extending southwards and somewhat westwards beyond the Tropic of Capricorn. Beyond it, though a good deal can be paralleled in the two other contemporary sources, Soligo and Martellus (#256), there are elements peculiar to Behaim, e.g. An intermediate position between these extremes is occupied by Henricus Martellus, 1489 (#256), who gives the Old World a longitudinal extent of 196A°.
Cooley describes as a€?the most unblushing volume of lies that was ever offered to the world,a€? but which, perhaps on that very ground, became one of the most popular books of the age, for as many as sixteen editions of it, in French, German, Italian and Latin, were printed between 1480 and 1492.

It is curious that not one of these learned a€?cosmographersa€? should have undertaken to produce a revised version of Ptolemya€™s map by retaining the latitudes (several of which were known to have been from actual observation), while rejecting his erroneous estimate of 500 stadia to a degree in favor of the 700 stadia resulting from the measurement of Eratosthenes (#112).
These copies were made use of in the production of charts on a small scale, the place names upon which, owing either to the carelessness of the draftsmen or their ignorance of Portuguese, are frequently mutilated to an extent rendering them quite unrecognizable. Foremost among these was JoA?o Rodriguez, who resided at Arguim from 1493-5, and there collected information on the Western Sahara. It is this northern island that retained its place on the maps until late in the 16th century, and, together with the islands of St.
John of Hildesheim (died 1375) wrote a popular account of their story, which was first printed in German in 1480. Oppert has satisfactorily shown that this mysterious personage was Yeliutashe of the Liao dynasty, which ruled in Northern China from 906 to 1125.
In the Sinus magnus of Ptolemy we also read: This sea, land and towns all belong to the great Emperor Prester John of India. Had he done this, the fact of India being a peninsula could not have escaped him; the west coast of Africa would have appeared more accurate.
Behaim had hopes of leading a voyage westward to Asia and sought the backing of the Emperor Maximilian. At your pleasure you can secure for this voyage a companion sent by our King Maximilian, namely Don Martin Behaim, and many other expert mariners, who would start from the Azores islands and boldly cross the sea.
Columbus, in the copy of the Toscanelli letter (made on the flyleaf of the Historia Rerum of Pope Pius II) gave Cathay as 130A° west of Lisbon and Zipangu as ten spaces, or 50A°, west of the legendary island of Antillia. Previously no doubts were entertained with respect to Magellana€™s statement, since it undoubtedly was well supported.
He may have participated in a minor exploration trip which one Fernan Dulmo planned in I486 and which had to have Azores as the point of departure. When the Kinga€™s Ministers assailed him with questions, he confided to the Ministers that he planned to land first on the promontory of St. It states inter alia with respect to the Land of Brazil: a€?The Portuguese have circumnavigated this land and they have found a sound which practically tallies with that of our continent of Europe (where we live).
On the other hand, SchA¶nera€™s drawings may very well be re- produced more or less exactly in other maps which took into consideration the discoveries in America. Yet the globe has survived, and its condition seems in no manner worse than it was when it was under treatment by the Bauers. 24, #115) to whom we are indebted for much of our knowledge of geography in antiquity, including the work of Eratosthenes whose relevant works, neither of which have survived, were On the Measurement of the Earth and Geographica, Cleomedes summarized the former, Strabo criticized the latter. The obliquity of the suna€™s course to that of the celestial sphere was of course well known; and hence the great circles of the equinoctial, and the ecliptic, or zodiacal circle, as well as the lesser circles, called the tropics, parallel with the equinoctial, were already familiar to the astronomers of Alexandria. But a much graver error than either of these two was that caused by the erroneous estimate of the actual distance between the two cities. Towards the north and south it was conceived that the excessive cold in the one case, and the intolerable heat in the other, rendered those regions uninhabitable, and even inaccessible to man. Democritus, two centuries before Eratosthenes, had asserted that it was half as long again as it was broad, and this view was adopted by DicA¦archus (#111), though recent discoveries had in his day materially extended the knowledge of its eastern portions. On the parallel of Rhodes, this total of 78,000 stades corresponds to about 140A° longitude, which is roughly the distance from Korea to the west coat of Spain. He appears in fact to have obtained, probably from the information collected by Patrocles, a correct general idea of the great projection of India in a southerly direction towards Cape Comorin, but was unable to reconcile this with his previously conceived notions as to its western and northern boundaries, and was thus constrained altogether to distort its position in order to make it agree with what he regarded as established conclusions.
It was doubtless, for reasons primarily commercial, that he first found his way to Portugal, where, shortly after his arrival, probably in the year 1484, he was honored by King John with an appointment as a member of the junta dos mathematicos [a nautical or mathematical council]. The sphere was then coated with whiting, upon which was laid the vellum that was to bear the design. Only two great circles are laid down upon it, the equator, divided into 360 degrees (unnumbered), and the ecliptic studded with the signs of the zodiac. But of men or of four-footed animals none had come to live there because of the wildness, and this accounts for the birds not having been shy. There is no indication on the globe of what Behaim considered the length of a degree to be, but even if he did not go as far as Columbus in adopting the figure of 562 miles for a degree, he presented a very misleading impression of the distance to be covered in reaching the east from the west. It is a relic of the continuous coastline that linked Southeast Asia to South Africa in Ptolemaic world maps that displayed a land-locked Indian Ocean, and it needs a name to identify it in argument. In the original French the author is called Mandeville, in German translations Johannes or Hans von Montevilla, in the Latin and Italian Mandavilla.
But even of maps of this imperfect kind illustrating the time of Behaim and of a date anterior to his globe, only two have reached us, namely the Ginea Portugalexe ascribed to Cristofero Soligo, and a map of the world by Henricus Martellus Germanus (#256). To Ferdinand we owe, moreover, the preservation of the account that Diogo Gomez gave to Martin Behaim of his voyages to Guinea.
As to the first it is remarkable that although Ptolemya€™s outlines of lakes and rivers have been retained, his place names have for the most part been rejected and others substituted.
The far-off places towards midnight or Tramontana, beyond Ptolemya€™s description, such as Iceland, Norway and Russia, are likewise now known to us, and are visited annually by ships, wherefore let none doubt the simple arrangement of the world, and that every part may be reached in ships, as is here to be seen.
Brandan and of the Septe citez [the Seven Cities] it still appears on Mercatora€™s chart of the world in 1587.
Having been expelled by the Koreans, Yeliutashe went forth with part of his horde, and founded the Empire of the Kara Khitai, which at one time extended from the Altai to Lake Aral, and assumed the title of Korkhan. His delineation is rather a€?hotch-potcha€? made up without discrimination from maps that happened to fall in his hands. The Emperor shrugged it off by passing it on to King John of Portugal in a letter written by Dr.
Pigafetta, Magellana€™s fellow-traveller and the chronicler of the world trip, has noted this fact. This trip referred however only to the discovery of new islands in the Azores waters and may not have been performed at all. Satirical Voltaire, displaying a truly French superficiality of judgment, expressed in 1757 his disbelief in that a€?one (!) Martin Behem of Nuremberga€? had travelled in 1460 (Behaim was born in I459) a€?from Nuremberg to the Magellan Straitsa€? on a mission for the Duchess of Burgundy(!).Voltaire was followed, as result of substantially more thorough studies, by Tozen in 1761, v.
We have from 15I5, the year when SchA¶nera€™s globe was made, also the so-called of Leonardo-representation the countries in the west (Book IV, #327). This can be inferred with certitude from the statement made in the pamphlet of 1508 to the effect that one had found Americaa€™s southern cape south of the 40A° S. Indeed, on examining the globe, a beholder may feel surprise at the brightness of much of the lettering. Nor can it be doubted that the discoveries resulting from the conquests of Alexander the Great (ca. Future scholars, however, would have a higher opinion of Eratosthenes, regarding him, a€?as the parent of scientific geographya€? and at least a€?worthy of alphaa€? in that subject, particularly for his remarkable measurement of the circumference of the earth. Moreover it appears that these conceptions, originally applied to the celestial sphere, had been already transferred in theory to the terrestrial globe. What mode of measurement had been resorted to, or how Eratosthenes arrived at his conclusion upon this point, we are wholly without information: but it may well be doubted whether he had recourse to anything like actual menstruation. That there might be inhabitants of the southern hemisphere beyond the torrid zone, or that unknown lands might exist within the boundless and trackless ocean that was supposed to extend around two-thirds of the globe from west to east, was admitted to be theoretically possible, but was treated as mere matter of idle speculation, much as we might at the present day regard the question of the inhabitants on Mars. The astronomer Eudoxus on the other hand maintained that the length was double the breadth; Eratosthenes went a step farther and determined the length to be more than double the breadth, a statement that continued to be received by subsequent geographers for more than three centuries as an established fact.
It was doubtless from the same source that he had learned the name of the Coniaci, as the people inhabiting this southernmost point of India; a name that hence forward became generally received, with slight modifications, by ancient geographers.
During his earlier years in Portugal he was connected with one or more expeditions down the coast of Africa, was knighted by the king, presumably for his services, and made his home for some years on the island of Fayal.
The vellum was cut into segments resembling the gores of a modern globe, and fitted the sphere most admirably. The Tropics, the Arctic and the Antarctic circles are likewise shown and in the high latitudes the lengths of the longest days are given.
On this ground the islands were called dos Azores, that is, Hawk Islands, and in the year after, the king of Portugal sent sixteen ships with various tame animals and put some of these on each island there to multiply.
The coast swings abruptly to the east at Monte Negro, placed by Behaim in 38A° south latitude. Behaim calls him Johann de Mandavilla, as in Italian, although six editions of his work printed in German, at Strasburg and Augsburg, were at his command. MA?ntzer, in 1495, saw hanging on a wall of the royal mansion in which he resided as the guest of Joz da€™Utra; and lastly, the map which Toscanelli is believed to have forwarded to King Affonso in 1474 in illustration of his plan of reaching Cathay and Zipangu by sailing across the Western Ocean.
Eastern Asia, with its islands, and Africa have, however, been copied from a map or maps which were also at the command of WaldseemA?ller (#310). It is this northern island that was searched for in vain between 1480 and 1499, and figures on Behaima€™s globe. Brandona€™s Island retained a place upon the maps, notwithstanding Vincent of Beauaisa€™ disbelief in the legend, until the days of Ortelius (1570) and Mercator; and as late as 1721 the Governor of the Canaries sent out a vessel to search for this imaginary island. The King George in Tenduk, whom Marco Polo describes as a successor of Presbyter John, was actually a relative of this Yeliutashe who had remained in the original seats of the tribe not far from the Hwang-ho, and of Kuku-kotan, where the Kutakhtu Lama of the Mongols resided when Gerbillon visited the place in 1688. In this respect, however, he is not worse than are other cartographers of his period: Fra Mauro and WaldseemA?ller, SchA¶ner and Gastaldo, and even the famous Mercator, if the latter be judged by his delineation of Eastern Asia. He writes: a€?But Hernando knew that is was the question of a very mysterious strait by which one could sail and which he had seen described on a map in the Treasury of the King of Portugal, the map having been made by an excellent man called Martin di Boemiaa€?. Apart from this there is nothing to indicate that he had undertaken from Fayal sea trips other than those to Europe. Murrin 1778, Cancellieri in 1809 and others, and more recently, above all by Ghillany in 1842, v.
The Magellan Straits are on the other hand on 52A° and prior to Magellan had no expedition, of which we know, sighted land near there. This, however, is due to the action of the a€? renovators,a€? who were let loose upon the globe in 1823, and again in 1847; who were permitted to work their will without the guidance of a competent geographer, and, as is the custom of the tribe, have done irreparable mischief. Thus the idea of the globe of the earth, as it would present itself to the mind of Eratosthenes, or any of his more instructed contemporaries, did not differ materially from that of the modern geographer. But as a mathematical ploy, in order to achieve a number divisible by 60 or 360, so as to correlate stades with his subdivisions or degrees, he emended this to 252,000 stades [a stade, stadion, stadia], originally the distance covered by a plough before turning, was 600 feet of whatever standard was used].
Indeed the difficulty which modern experience has shown to attend this apparently simple operation, where scientific accuracy is required, renders it highly improbable that it was even attempted; and the round number of 5,000 stades at once points to its being no more than a rough approximation. A smith supplied two iron rings to serve as meridian and horizon, a joiner and a stand, and there was provided a lined cover as a protection against dust. The only meridian which is drawn from pole-to-pole 80 degrees to the west of Lisbon is graduated for degrees, but also unnumbered.
Arthur Davies, in his discussion of the Martellus map refers to it as the Tiger-leg peninsula; in others it is referred to as Catigara.
This is the point reached by CA?o in 1483, and its true position is 15A° 40a€™ south; a Portuguese standard marks the spot.
Pipinoa€™s Latin version, on the other hand, is divided in this manner, and Behaim in seven of his legends quotes these divisions correctly. One could conclude from this that he is indebted to an Italian map and not to a perusal of his Travels for the two references on the globe.
A comparison of that cartographera€™s map with Behaima€™s globe leaves no doubt as to this, unless we are prepared to assume that WaldseemA?ller took his information from the globe, which Ravenstein concludes to be quite inadmissible. The island Seilan has a circuit of 2,400 miles as is written by Marco Polo in the 19th chapter of the third book. Tarsis (Tarssia) is shown on many medieval maps in a similar position, for instance, on the Catalan Atlas of 1375, where the three kings are shown on horseback about to start for Bethlehem.
His famous globe which he made in I491-92 in Nuremberg does not show even the slightest trace of a knowledge of countries or islands beyond the Azores. A smith supplied two iron rings to serve as meridian and horizon, a joiner and a stand, and there was provided a lined cover as a protection against dust.A  In 1510 the iron meridian was displaced by one of brass, the work of Johann Verner, the astronomer. As a result numerous place-names have been corrupted past recognition, and if one desires to recover the original nomenclature of the globe we must deal with it as a palimpsest.
The same thing was the case in ancient times, and it is highly probable that if you could now recover the map of the world as it was generally received in the time of the first Ptolemies, we should find it still retaining many of the erroneous views of Herodotus and HecatA¦us (#109 and #108). For all geographical purposes, at least as the term was understood in his day, the difference between the geocentric and the heliocentric theories of the universe would be unimportant.
A conversion to modern units of measure finds Eratosthenesa€™ calculation to be somewhere between 45,007 km (27,967 miles) to 39,690 km (24,663 miles), as compared to actual equatorial circumference of 40,075 km (24,902 miles), there has always been some controversy over the equivalent modern length of a stade as used by Eratosthenes. But even considered as such, it exceeds the truth to a degree that one could hardly have expected, in a country so well known as Egypt, and in an age so civilized as that of the Ptolemies. The sea is colored a dark blue, the land a bright brown or buff with patches of green and silver, representing forests and regions supposed to be buried beneath perennial ice and snow. This feature is a remnant of Ptolemya€™s Geography that evolved when the Indian Sea was opened to the surrounding ocean.
On the eastward trending coast, there are names that seem to be related to those bestowed by Diaz, and the sea is named oceanus maris asperi meridionalis, a phrase which doubtless refers to the storms encountered by him. We should naturally conclude from this that this was the version consulted if on other occasions he had not quoted the chapters as given in the version which was first printed in Ramusioa€™s Navigationi e viaggi in 1559.
The first of these (near Candyn) refers to the invisibility of the Lodestar in the Southern Hemisphere and the Antipodes, and is one of the four original statements of the learned doctor, and the second describes the dog-headed people of Nekuran, which he has borrowed from Odoric of Portenone and enlarged upon.
It was on the same map that Ritter von Harff, who returned to Germany in 1499 after a pilgrimage to the Holy Land, performed his fictitious journey from the east coast of Africa, across the Mountains of the Moon and down the Nile to Egypt. Brandana€™s Island is generally associated with the Canaries, as on the Hereford map of 1280 (Book II, #226), but Dulcerta€™s Insulla Scti Brandani sive puellarum (1339) lies further north, while Pizzigania€™s San Brandany y ysole Pouzele lie far to the west (1367).
Finally, in 1939 the problem was definitively clarified as regards the connection between Americaa€™s discovery and the great Nuremberg scholar by answering it in the negative.
He was all the more sure to find a sound as he had seen it on a sea map made by Martin de Bohemia.
He owned the map, but the master-drawer did made this representation which is extremely poorly executed.
Such a process, however, might lead to the destruction of the globe, whilst the result possibly to be achieved would hardly justify running such a risk. Alexandria is in fact situated at a distance of about 530 geographical miles (5,300 stades) from Syene, as measured on the map along the nearest road but the direct distance between the two, or the arc of the great circle intercepts between the two points, which is what Eratosthenes intended to measure, amounts to only 453 miles or 4,530 stades.
Perhaps the most attractive feature of the globe consists of 111 miniatures, for which we are indebted to Glockenthona€™s clever pencil. The placing of Madagascar and Zanzibar approximately midway between this peninsula and the Cape must be another feature of some antiquity. Owing to the exaggeration of the latitudes, Monte Negro falls fairly near the position that the Cape of Good Hope should occupy.
On Behaima€™s globe may be traced twenty-one names, out of about forty to be found on WaldseemA?llera€™s map of 1507, and four of them mark stages of the worthy knighta€™s journey.
The evidence which carried the greatest weight was doubtlessly the letter which on July 14th, 1493 was written to King John II of Portugal by Hieronymus Miinzer who was a friend of Behaim and was in close touch with him. Also this representation of the newly discovered South America shows a wide sound that separates America from the hypothetical southern continent of Ptolemy.
But we have no information as to the data on which these first crude attempts were based, or the mode by which he authors arrived at their results. Eratosthenes, therefore, in fixing the length of this arc at 5,000 stades, was 470 beyond the truth.
The vacant space within the Antarctic circle is occupied by a fine design of the Nuremberg eagle with the virgina€™s head, associated with which are the arms of the three chief captains by whose authority the globe was made, namely, Paul Volckamer, Gariel NA?tzel and Nikolaus Groland, Behaim and Holzschuher. It is noticeable that the Soligo chart ends in 14A° south, which is near the limit of Behaima€™s detailed knowledge.
Behaim had ample opportunity to study the proposals of Columbus and the map(s) that accompanied them.
This letter which knew nothing about Columbusa€™ discovery was written to suggest to King John a western trip across the ocean in order to reach East Asia. Another contemporary map, designed by the Turkish map-maker Piri Rea€™is in 1513 (Book IV, #322) even regarded South America as a peninsula of the southern continent and therefore did not contain any separating sound.
The vacant space within the Antarctic circle is occupied by a fine design of the Nuremberg eagle with the virgina€™s head, associated with which are the arms of the three chief captains by whose authority the globe was made, namely, Paul Volckamer, Gariel NA?tzel and Nikolaus Groland, Behaim and Holzschuher.A  There are, in addition, 48 flags (including ten of Portugal) and five coats of arms, all of them showing heraldic colors. We might conclude, therefore, that Behaima€™s contribution was to reproduce this coast from a similar chart, and to add some gleanings from the Diaz voyage round the Cape. This was the origin of Behaima€™s later plan to sail to Asia and the source of his concepts of the distances involved. This letter would of necessity have referred to Behaima€™s legendary discoveries in the western ocean, if such discoveries had been made, since Behaim certainly knew about the letter and approved of it.
This shows that individual mapmakers used their imagination arbitrarily in their efforts to combine cartographically the new countries of which only fragments were known.
The difference in latitude between Alexandria and Syene really amounts to only 7A° 5a€™, so that the direct distance between the two cities, supposing them to have been really situated on the same meridian (as Eratosthenes assumed them to be) would not have exceeded 425 miles or 4,250 stades, instead of 5,000. The two personal names are not to be found on any other map: in conjunction with the attempt made to associate Behaima€™s own voyage with the discovery of the Cape, we are justified in assuming that this portion of the globe at least was designed in a spirit of self-glorification.
Leonardoa€™s map conceived all the new western countries as islands: the islands and coasts of the mainland which were discovered by Columbus, Labrador-Newfoundland in the north, found by Cabot, and the coast line of North America, cursorily explored by Cabral, Verrazano and others.
Forty-eight of them show us kings seated within tents or upon thrones; full-length portraits are given of four Saints (St. How arbitrary were the designs of the drawers of these earliest maps of America is shown inter alia by the Ruysch map of 1508 (Book IV, #313) which had inserted a connecting water way even between Honduras and Yucatan or also the much-discussed Anian Strait in northern America which were sought even late as the beginning of the 19th century. As far as he knew in 1492, Columbus had not gained support for his enterprise in Portugal or Spain and there was no logical or moral reason why he should not seek German support. Eleven vessels float upon the sea, which is populated by fishes, seals, sea lions, sea-cows, sea-horses, sea-serpents, mermen, and a mermaid.
The land animals include elephants, leopards, bears, camels, ostriches, parrots, and serpents.A  The only fabulous beings that are represented among the miniatures are a merman and a mermaid, near the Cape Verde Islands, and two Sciapodes in central South Africa, but syrens, satyrs, and a€?men with dogsa€™ heads are referred to in some of the legends. Nor do we meet with the a€?Iudei clausi,a€™ or with a a€?garden of Eden,a€™ still believed in by Columbus.A  There is a curiously faulty representation of the Portuguese arms, especially for someone like Behaim who had lived in and sailed for that country for many years.
