Sande women and aesthetics of excision in Sierra Leone

"The Sande Society of the Mende people of Sierra Leone is a secret female regulatory society that both guards and transmits the ideals of feminine beauty so fundamental to the aesthetic criteria in Mende culture. In this eloquent and moving book, Sylvia Ardyn Boone describes the Society, its rituals and organization, and the mask worn by its members. Her book is an evocative account of Mende life and philosophy as well as a unique contribution to the study of African art, one based on African conceptions about the person and the human body."
