A related — though not as ancient — art is phrenology, the study of the bumps on the head. Phrenologists have identified 40 bumps of variousshapes and sizes on the human head. They "read" these bumps to identify a person's talents and character. For example, a bump between the nose and forehead is said to be present in people who have natural elegance and a love of beauty. A bump behind the curve of the ear is the sign of a courageous and adventurous person.
