Yoruba Ibedji (effigies) representing dead twins, Nigeria, West Africa. Some Yoruba tribes revere twins, who are thought to bring luck to household and tribe. The death of one is a great calamity. A wooden figure, called Ibedji, is made to house the spirit of the dead child and be a companion for the surviving twin. The Ibedji figure becomes a cult-object in the family and the mother tends it, offers it food and decks it with beads, cowrie shells, red camwood and other adornments.
