Odin and Freyja are the “stars” of the Norse pantheon. The most famous god of the warlike Aesir, and the (only) goddess of the Vanir, they are surprisingly alike. Both are magicians, both gather the slain, and both take an interest in mortals.
The Irish goddess Boand is famous for two things: she is the mother of the young god Aengus, whom she carried to term in a single (nine-month-long) day, and the river Boyne is named for her, after she caused it to gush forth from a magical well.
Gefjun will be forever be famous as the goddess who gave Zealand to Denmark. The Danes immortalized her feat with a fountain in Copenhagen harbour, showing her and her oxen ploughing out the land.
She has many similiarities to Odin, as a goddess who travels between worlds, tricks mortals, and straddles moral and sexual boundaries. Far from being an earth and ploughing goddess, Gefjun is a magical and complex figure.
Odin and Brigit may not seem like the most similar deities, but they actually do have more in common than you might think. Both are patrons of poets, both give up an eye voluntarily, and both these losses are connected with water.
