Humans have always been compelled by faces. We like to look at them, we like to draw them, we like to take pictures of our own face, we see them in the moon and in our toast and in a random outcropping of rocks. We look at a friend’s face and instantly know what she’s feeling. We look at a 700-year-old painting of a face and we can feel what that person’s world is like on the inside.
Our depiction of the human face hasn’t remained constant, however. Using a technique called face averaging, we can see how the art of the face has evolved.
