Figure 66: Head of Arrotino (the spy, the knife grinder, and so on) 1854 - 1856

Guillaume Duchenne's "Figure 66: Head of Arrotino" (1854–56) is a striking photographic study of a plaster cast, presented in an oval format. Duchenne, a physician and pioneer of photographic documentation of human anatomy, used electric stimulation to create a range of facial expressions. The image, one of many in his groundbreaking publication *Mécanisme de la Physionomie Humaine,* reveals the expressive potential of the human face, making it a valuable resource for artists and scientists alike. The Metropolitan Museum of Art in New York holds this fascinating print.
