Sami religion was not uniform across Sapmi, which stretches from central Norway and Sweden through Finland into the Kola peninsula, and the names of the powers differ by region and by the language of the recorder. A layered scheme is usual: sky and creator figures above, thunder, sun and fertility powers between, the dead below. Horagalles, the thunder god, appears widely; Beaivi is the sun; Maderakka and her daughters attend birth and children; Jabmeakka governs the land of the dead. Some of these names show contact with Norse religion, and how much is borrowed and how much is old Finno-Ugric material is disputed.
Offering was made at a sieidi, a stone, rock formation, spring or tree that was not itself a god but a place where the relationship was transacted. Sieidi received reindeer antlers, bones, fish, fat, coins. Many are still known, still visited, and still receive offerings, which is one reason their locations are not always published.
The bear hunt is the best documented ritual complex, recorded in detail across Sami and neighbouring Finnic groups. The bear was addressed with indirect language, killed under strict procedure, eaten at a communal feast, and its bones buried in anatomical order so that it could return. The point was not honouring a symbol but keeping an agreement with an animal understood to be aware of how it was treated.
Reindeer herding shaped the annual round for many Sami, and the sacred year followed the herd, the sun, and the fishing rather than a fixed calendar. That is one reason the tradition proved hard for missionaries to locate and stamp out: much of it had no building and no fixed date.
