"Commentators such as Strömbäck have long noted the similarities between Saami religion and the practice of seiðr. Indeed, a significant portion of the accounts of seiðr in the Norse literature recount that the art is either learned from or practiced by "Finnish wizards," which in Old Norse meant Lappish (Saami) shaman. The powers attributed in the sagas to the "Finnish" sorcerer, actually Saami (Lapps) are those of the seið-worker in many cases. "
