Die Yoruba in Nigeria betrachten die Geburt von Zwillingen als einen besonderen Segen. Wegen der hohen Sterblichkeitsrate sind Yoruba-Mütter aber häufig mit dem Tod eines Kindes konfrontiert. Die Yoruba glauben, dass die Zwillinge gemeinsam nur eine einzige Seele haben. Beim Ableben eines Zwillings wäre der überlebende Zwilling lebensunfähig. Die angefertigte Ibeji-Statue für den verstorbenen Zwillingsteil kann somit die andere halbe Seele enthalten. Darüber hinaus ist die Linie zwischen Leben und Tod für die Yoruba nicht absolut. Es gibt für sie ein enges Wechselspiel zwischen der spirituellen und der materiellen Welt. Der Zwillingskult zählt zu den ältesten Kulten der Menschheit. The Yoruba people of Nigeria consider the birth of twins a special blessing. Due to the high mortality rate of twins, Yoruba mothers are often confronted with a child’s death. The twins are believed to share only one soul. When a twin dies, the surviving twin would be unable to live. The Ibeji sculpture for the deceased twin can thus contain the other half of the soul. Yorubas do not draw a strict line between life and death. To them there is a close interaction between the spiritual and the material world. The Twin Cult is one of the oldest known cults of mankind.
