Nanook

Nanook, from the Inuktitut nanuq, "polar bear", is the spirit lord and master of polar bears in Inuit tradition, understood as controlling the availability of bears to hunters much as Sedna controls the sea mammals, and requiring similarly careful, respectful treatment of a killed bear's body and remains to maintain his goodwill toward the hunter's community.

The polar bear itself held an unusually significant and dangerous place in traditional Inuit life, both a valuable source of meat, fur and material and one of the few animals genuinely capable of killing a human hunter in return, and this real, mutual danger is reflected in the seriousness with which traditional practice treated the ritual obligations owed to Nanook, including specific taboos governing how a bear's body could be handled, distributed and disposed of after a successful hunt. Some Inuit narrative traditions describe Nanook as himself resembling an enormous or otherwise supernatural bear, blurring the line between a spirit ruling over an animal species and the animal's own most powerful, semi-divine exemplar, a pattern also found in other circumpolar master-of-animals traditions.

Nanook's function closely parallels both Sedna's rule over sea mammals within Inuit tradition itself and Bugady Enintyn's rule over game animals within the unrelated but structurally comparable Evenki tradition of Siberia, together illustrating a broader circumpolar pattern in which each major category of hunted animal a community depends on tends to have its own specific spirit guardian whose goodwill must be actively maintained through correct ritual conduct, rather than a single generalised nature spirit covering all game indiscriminately. This granularity, a distinct spirit for sea mammals and a distinct spirit for the polar bear specifically, reflects how precisely Inuit traditional religion tracked the practical realities of a genuinely difficult and dangerous subsistence economy, in which success or failure at securing any one category of resource carried immediate, serious consequences for a community's survival through the Arctic winter.

Contemporary discussion of Inuit traditional knowledge, including material gathered under Inuit Qaujimajatuqangit, continues to present respectful treatment of the polar bear as an important cultural value connected to this older spiritual framework, even as the practical context of Inuit life has changed substantially.
