Hawaiian religion is set out at greatest length in the Kumulipo, a chant of two thousand lines tracing the world from darkness through the emergence of coral, of sea and land creatures in paired sequence, and finally of people and of the chiefly line that commissioned it. Martha Beckwith's translation and commentary is the standard scholarly edition. As a genealogical chant it is at once a cosmology and a claim to rank, because in Hawaiian terms those are the same thing.
Four great gods stand at the centre: Ku, associated with war, forest and the deep sea; Kane, with fresh water and with life; Lono, with agriculture, rain and the Makahiki season; and Kanaloa, with the ocean. Beside them stand the family gods, the aumakua, who take the form of a shark, an owl or another creature and belong to particular lineages, and Pele, whose presence in the volcano is not a matter of the past tense.
The kapu system regulated all of it. Restrictions governed what could be eaten and by whom, who could enter which ground, and how a person of rank was to be approached, and the penalty for breach could be death. Beckwith's collection of the wider mythology sets the deities and the heroes within that framework rather than extracting them from it.
