Metoposcopy redux

Abstract

Phrenology is the pseudoscience in which practitioners claim that they can discern one's character and personality traits by studying the structure of the skull. Long before "head bumps" were viewed as determinants of character, skin lines were analyzed to provide similar information and to divine one's future. Palmistry, also called chiromancy, is the interpretation of the lines of the palms and is one of the oldest forms of divination. A similar pseudoscience, metoposcopy, suggests that facial lines and marks, mainly forehead lines, can reveal one's personality and foretell events in one's future. Metoposcopy was first practiced by the ancient Chinese and was popularized during the Renaissance by Girolamo Cardano and later by Richard Saunders. Metoposcopy is a largely forgotten form of skin-based pseudoscience that is no longer practiced today, unlike palmistry.
