In Norse mythology, Sigyn (Old Norse "victorious girl-friend") is a goddess and is the wife of Loki. Sigyn is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In the Poetic Edda, little information is provided about Sigyn other than her role in assisting Loki during his captivity. In the Prose Edda, her role in helping her husband through his time spent in bondage is stated again, she appears in various kennings, and her status as a goddess is mentioned twice. Sigyn may appear on the Gosforth Cross and has been the subject of an amount of theory and cultural references.
