Freya (Old Norse Freyja, “Lady”) is one of the pre-eminent goddesses in Norse mythology. She’s a member of the Vanir tribe of deities, but became an honorary member of the Aesir gods after the Aesir-Vanir War. Her father is Njord. Her mother is unknown, but could be Nerthus. Freyr is her brother. Her husband, named Odr in late Old Norse literature, is certainly none other than Odin, and, accordingly, Freya is ultimately identical with Odin’s wife Frigg (see below for a discussion of this).
Freya is famous for her fondness of love, fertility, beauty, and fine material possessions – and, because of these predilections, she’s considered to be something of the “party girl” of the Aesir. In one of the Eddic poems, for example, Loki accuses Freya (probably accurately) of having slept with all the gods and elves, including her brother. She’s certainly a passionate seeker after pleasures and thrills, but she’s a lot more than only that. Freya is the archetype of the völva, a professional or semiprofessional practitioner of seidr, the most organized form of Norse magic. It was she who first brought this art to the gods, and, by extension, to humans as well. Given her expertise in controlling and manipulating the desires, health, and prosperity of others, she’s a being whose knowledge and power are almost without equal.
