Gylfaginning, which is part of Snorra Edda, was composed in Iceland in the 13th century, and holds the stories of many of the Pre-Christian myths of northern Europe. It is believe to have been composed by the Icelander Snorri Sturlusson. Snorra Edda consists of three separate parts, Gylfaginning, Skaldskápamáland Háttatal, all functioning together as a greater work and guide for the aspiring medieval poet and storyteller.
Óðr is named amongs the gods and said to be Freyja‘s husband and the father of Hnoss. He is mentioned in Völuspá 25, Hyndluljóð 46-47 as well as Gylfaginning and Skáldskaparmál. It has been suggested that Óðr is indeed another name for Óðinn.
