As discussed in an earlier post about Odin, Frigg is one of the earliest deities known in Norse mythology. She is the first wife of Odin, the High One, and the mother of other gods such as Baldr. Frigg is widely recognized as the goddess of motherhood, marriage, and prophecy. Her name appears frequently in the Poetic Edda, especially in the Völuspá, Lokasenna, and Oddrúnargátr. Perhaps the most famous story involving Frigg is the weeping for her beloved and beautiful son Baldr, who died due to Loki's trickery. Loki deceived Höðr, another son of Frigg and Odin, into hurling a projectile made of mistletoe at Baldr, leading to his untimely death.

Contrary to popular belief, the name "Friday" does not derive from Freyja. Instead, historical sources trace it back to the Old English term Frīġedæġ, which translates to ‘day of Frigg.’ This term is cognate with Old Frisian, Middle Dutch, and High German languages, all relating back to Frigg. There is no surviving evidence mentioning Freyja outside of Scandinavian sources, affirming that the day was indeed named after Frigg.

The term "Ásynjur" is first mentioned in the Prose Edda and refers to Norse goddesses, with Frigg among the highest. Only Freyja stands as her equal in prominence. According to these texts, Frigg dwells in Fensalir. Significant figures associated with her include Fulla, who carries Frigg's ashen box, looks after her footwear, and shares her secrets, effectively acting as her handmaiden. Another is Lofn, who is given permission to arrange unions among men and women. Hlín is tasked with protecting those deemed worthy, and Gná is sent into the worlds to do Frigg's bidding.
