Louhi (also called Pohjan akka, "the old woman of the North") was the witch-queen of Pohjola, the dark land of the North in Finnic mythology — a place of cold, of magical danger, of monstrous offspring, and (paradoxically) of the Sampo, the great source of plenty that her own folk had somehow obtained. She was the principal antagonist of Väinämöinen and his companions throughout the Kalevala; she set them impossible tasks, demanded the Sampo's forging as a marriage-price for her daughter, fought them in great battles, and at last pursued them across the sea when they had stolen the Sampo, transforming herself into a great eagle to attack their ship. In the climactic battle, the Sampo was broken and lost in the sea; Louhi, defeated, returned to Pohjola with only its lid as her share, and Pohjola declined into the cold and barren place that Finnish tradition imagined it had been.
Her character was malign but not unmotivated; she was the queen of a land that needed the Sampo's plenty as much as Finland did, and her resistance to its theft was reasonable from her people's standpoint. The Kalevala, like much oral epic, gives the antagonist a coherent perspective even while siding with the protagonists. Louhi is one of the most fully developed female figures of Finnic mythology and has had a substantial modern reception in Finnish literary and cinematic tradition.
