Scandinavian or Norse mythology refers to the pre-Christian beliefs, legends and religion of the Scandinavian people. It is the most widely known version of the older Germanic paganism and Germanic mythology.
Although it does have tales of normal people learning the stories of the the gods from the gods themselves, it is not a revealed religion in the sense of truth being handed down from the divine.
Most information was passed down orally, and has now been lost; some information however was recorded in the Eddas and the Heimskringla by Snorri Sturluson – a Christian scholar who believed that Pagan deities were men and women rather than devils.
