We all know the old tale - how it's come to mark the chasm of creative madness. On 23 December, 1888 Vincent Van Gogh - following an argument with fellow lodger and artist Gaugin - retreated to his room, where he took a razor to his left ear; severing it, wrapping it in paper, and delivering it to a woman at a brothel both he and Gaugin used to frequent. He was found unconscious the next morning by a policeman and was taken to the hospital.
