With the recent passing of "Exorcist" author William Peter Blatty, the Washington Post takes a photographic journey back to the origins of the story that inspired Blatty to write the book. In 1949 the Catholic church issued a rare consent order to allow an exorcism to be performed on a young boy who priests feared had been possessed by a demon. Doctors and psychiatrists have long speculated that the cause of the boy's affliction was rooted in natural medical explanations but the priests reported that they witnessed events that could not have been caused by any earthly phenomenon. The priests involved remained made few public comments after the exorcism, though there are some sketchy diary entries that shed a bit of light on the proceedings. The boy who was the center of the case is still alive and is now 78 years old but has never commented publicly on his ordeal or his memories of it, if any. Unless and until he does, there will always be debate about what actually occurred in an ordinary house occupied by an ordinary family who would inspire one of the most extraordinary novels and films of the 20th century.
