Freyja (sometimes anglicized as Freya) is a major goddess in Germanic paganism, particularly in its late form, Norse paganism, where numerous surviving tales either involve or feature her. While there are some sources suggesting that Freyja was called on to bring fruitfulness to fields or wombs, in the Eddas, she was portrayed as a goddess of love, beauty, and fertility.
