Part one of two. The classicist examines the nude in western art and its troubling power to provoke ideas about gender, sex and moral transgression. Mary starts with a statue of Aphrodite by Praxiteles and Titian's Venus of Urbino, asking how a woman like her should respond to the artworks, and considers the challenge of depicting the female nude for a woman artist by looking at the work of 17th-century painter Artemisia Gentileschi. In a life-drawing class, Mary joins a hen party as they attempt to sketch a naked man.
