What's in a face? The face is where all our senses come together, but we also perceive each other's faces through the prisms of culture and technology. Historian Fay Bound-Alberti's new book examines how our perceptions of the face have been shaped by ancient ideas of morality, social hierarchy and psychology. 

Guest: Dr Fay Bound-Alberti is a professor of Modern History at King’s College London, and the author of ‘The Face: A Cultural History’
