Eshu, trickster god of the Yoruba of Nigeria, an essentially protective, benevolent spirit who serves Ifa, the chief god, as a messenger between heaven and earth. Eshu requires constant appeasement in order to carry out his assigned functions of conveying sacrifices and divining the future. One myth depicts Eshu as tricking Ifa out of the secrets of divination; another, in which Eshu restores Ifa from his imprisonment in a palm tree, casts him as the founder of the Ifa religion.
