Engraving by Iagemann after an original painting by Schmidt. Gall (1758-1828) gave popular lectures on phrenology (the study of the shape and size of the skull as a supposed indication of mental abilities and character). His ideas, including the theory that a person's talents and qualities were traced to particular areas of the brain, were seen as being subversive of religion. Phrenology has been long since discredited. Dimensions: 270mm x 380mm.
