Óðr (Ódr), in Norse Mythology, is the husband of goddess Freyja and is father of Hnoss and Gersemi. Although the precise mythological meaning of the name is uncertain, the word itself means "wit, soul, spirit".Snorri Sturluson wrote in his books as follows: "Freyja is ranked next to Frigg: she is wedded to a man called Óðr, and their daughter, named Hnossa, is so very handsome that whatever is beautiful and precious is called by her name (hnosir.) But Óðr left his wife in order to travel into very remote countries. Since that time Freyja continually weeps, and her tears are drops of pure gold. She has a great variety of names, for having gone over many countries in search of her husband, each people gave her a different name. She is thus called and Hörn, Gefn, Sýr, and also Vanadís." (The Prose Edda, Gylfaginning (35), I. A. Blackwell's translation).
