Darwin on physiognomy. Man with a facial expression induced by electrical probes applied by French neurologist Guillaume Duchenne (1806-1875). Duchenne used the new technique of photography to record idealised facial expressions thought to reveal the emotions of the soul. Here, the corrugator supercilii and platysma muscles are stimulated, and the mouth opened. This image is from Darwin's work 'The Expression of the Emotions in Man and Animals' (1872). The original appeared in Duchenne's 'Mecanisme de la physionomie humaine' (The Mechanism of Human Physiognomy, 1862). This work was subtitled: 'The Electro-Physiological Analysis of the Expression of the Passions, Applicable to the Practice of the Plastic Arts'.
