Skull of a prostitute

The skull pictured in this 20th century lithograph, supposedly that of a woman who worked as a prostitute, is thought to have come from the collection of Franz Joseph Gall, founder of modern phrenology. It's referred to in Gall's 1819 publication "The Anatomy and Physiology of the Nervous System in General, and of the Brain in Particular."

The illustration is meant to demonstrate the phrenological theory that the skull's shape and size relates to character.
