Our ability to recognize faces resides in the right fusiform gyrus of the inferior medial temporal lobe of the brain. People with damage to the front of that region are face-blind, like [Chuck] Close. People with damage to the back of that region cannot see a face at all. Close is probably the only person in the history of Western art to paint portraits without being able to recognize individual people. Why, then, did he focus on being a portrait artist? Close says his art was an attempt to make sense of a world he didn’t understand. For him, it’s not so strange that he makes portraits. He was driven to make portraits because he was trying to understand the faces of people he knows and loves and commit them to memory. For him a face has to be flattened out. Once he flattens it, he can commit it to memory in a way that he cannot if he’s looking at it head-on. If he looks at you and you move your head half an inch, it’s a new head for him that he has never seen before. But if he takes a photograph of the face and flattens it out, he now can effect the translation from one flat medium to another.
