Sun is the elder of the paired demiurges whose exploits pervade Northern Jê mythology, of which the Kĩsêdjê form a part. In the shared cycle Sun and his companion Moon travel through a still-forming world, and their deeds and quarrels fix its features and settle the hard conditions of human life, including mortality. Sun is typically the cannier and more successful of the two, Moon the imitator whose blunders bring difficulty into the world. Sources differ on how far the Kĩsêdjê elaborate this cosmogonic pair relative to their neighbours and relative to their more distinctive emphasis on the acquisition of song and ceremony, but the demiurge motif is well attested for the Northern Jê to whom the Kĩsêdjê belong.
