This program introduces the pseudo-scientific field of phrenology, the study of the size, shape, and protuberances of the skull to diagnose disease and interpret personality. Phrenology became popular in the 18th century, but was quickly discredited by many mainstream medical establishments. Some remain committed to the idea, however, and continue to study it to this day. This program details the tools and techniques that practitioners use to observe and measure the cranium, as well as the field's alleged connection to modern neurology. Also included are reports of phrenological studies and interpretations done on famous figures such as Jesus Christ, Julius Caesar, and Rasputin.
