In Tao (Yami) cosmology the sky is a tiered world inhabited by luminous deities, the greatest of whom shaped the first human beings. Gazing down upon Pongso no Tao, the creator let fall a stone and a length of bamboo onto the summit of the island's central mountain; from the stone one man came forth and from the split bamboo another, and these became the two founding ancestors of humankind. Sources differ on whether a single supreme god or a company of sky-dwelling deities performed the act, and the creator's personal name is not consistently preserved in the recorded texts, where he is most often simply the god of the sky. He remains a remote figure, invoked in origin narratives rather than in the daily ritual life, which centres instead on the flying-fish cult and on the placation of the anito, the spirits of the dead.
