Sibö (Bribri and Cabécar; Sibú among the Boruca and Spanish speakers, Zbö among the Naso) is the central deity of the Talamancan peoples of southeastern Costa Rica and adjacent Panama. He is the world-transformer and culture-hero who, in the time of the cruel primordial Sòrbulu, was born as the grandson of their elder Sórkura and grew up destined to displace him. Having killed Sórkura, Sibö ordered the earth into its present shape, brought the girl-child Iriria up from the underworld and made the fertile soil of her body, and planted the human clans as kernels of maize — the foundational myth of Bribri-Cabécar identity, in which descent groups are literally 'seed-stock' (ditsö̀). He taught people which foods are safe, how to farm, and the rules of clan and kinship, and he gave the awápa (shamans) their songs, ritual language and sacred stones. He often appears as a collared king-vulture. After ordering the world he withdrew, remaining a remote high god invoked through chant rather than image.
