Book excerpt: "Spirits Speak presents a selection of the most important African masks found in major museums and renowned private collections around the globe: an overview such as has never been compiled in this way before. Artistic mastery, charisma, age and authenticity were paramount selection criteria with only the very best examples representing each well-known mask type. An introductory essay elucidates the conceptual intricacies and varying functions of the masks and sweeps away deep-rooted misunderstandings. Enlightening commentaries offer background information about the function and origins of each mask's use within the ethnic groups from which they originate, and a foldout map places them in their original geographical context."--BOOK JACKET.
