Willett, Frank. African Art. New ed. London: Thames & Hudson, 2002.

The art of the Fang, the BaTeke, the BaKota, and other African people sis extraordinarily vigorous and shows a brilliant sense of form. The substantial aesthetic impact that their works have had on the development of twentieth-century Western art - on Picasso, Derain, Braque, and Modigliani, among others - continues to this day. This classic study reveals the astonishing variety and expressive power of the art of a continent that contains more distinct peoples and cultures than any other. The revised edition has been updated throughout, incorporating recent research and additional illustrations, plus a new chapter and extended bibliography. It remains an invaluable resource for students and for anyone interested in African art.
