This 66-page catalog, published on the occasion of the "Terrific Twins" exhibition in 2009, serves as a valuable resource for specialists studying the cult of twins among the Yoruba of Nigeria. Richly illustrated, this work is the result of collaboration between José De Goede, Dutch gallery owner Poekelien Lingbeek, and Ursula Voorhuis from the Afrika Museum in Berg en Dal. Together, these ibeji enthusiasts have brought together treasures from their respective collections to present an outstanding ensemble of ibeji. The aesthetic quality of the pieces, coupled with their antiquity, makes a significant contribution to the study and appreciation of ibeji within the context of Yoruba art. This catalog will meet the expectations of discerning collectors and researchers, thus enriching any library specializing in the subject of the twin cult in West Africa.
