Poseyemu, 'Sun Youth,' is the great culture hero of the Tewa and one of the most widely known figures across the Pueblo world. Born of the Sun and a maiden of the pueblo, he grows to be the first and greatest shaman, able to speak with the powers of the sky, and he teaches the people ceremony, cultivation, and law; Tewa tradition credits him with instituting sodalities such as the Kosa clown cult. Traditions tell of his departure or overthrow and his pledge to return, a promise that carried political force: during the Pueblo Revolt of 1680 Spanish authorities recorded rebels acting on the mandate of a lieutenant of 'Po he yemu.' In colonial and later accounts he is repeatedly conflated with Montezuma and, in mission contexts, with Jesus, forming what scholars have called a Pueblo mythological triangle. Sources differ on whether Poseyemu was purely a mythic being or the memory of a historical leader of the ancestral migration into the Rio Grande valley.
