Early on in the series, we caught quick glimpses of some grisly, nightmarish artwork assumedly covered up by Chad (Zachary Quinto) and Patrick (Teddy Sears) prior to the Harmons moving into the Murder House. From what we could see, it looked as though someone decided to illustrate Dante's Divine Comedy on the walls of the study. Whether it was added by the Montgomerys (the house's original residents) or some later tenants who had gone off their rockers was never revealed, but what role did that art play, and why did we never get to fully see it?
