The religion of the Viking age, the pre-Christian faith, presents itself as a syncretism, It is quite peculiarly evident from the tradition surrounding the origin of the gods in Åsgard. The gods behind the palisade of this mythological dwelling place were of two kinds, the result of an exchange of hostages after war between the æsir and the vanir. From the flock of vanir came the two fertility-gods: Njgrbr and Freyr to dwell in Åsgard and be accepted there on equal terms with the other gods around the "allfather", Othin. This quite remarkable information, concerning the syncretism of the eddic religion, is generally interpreted as a historic reminiscence of a contrast between a fertility religion, and a more aristocratic and warlike religion attached to the cult of Othin. The fertility religion then is often conceived of as old traits belonging to the indigenous population of Scandinavia, while the Othin-cult as something which was introduced by the same innovations that brought the Indo-European boat-axe people to our part of the world. We know the result of the process that created the heathen religion which reigned in our countries at the time Christianity was introduced here, but we are highly bewildered when faced with the task of describing the syncretistic process itself, and the religions that were a part of it. This is true despite our abundant material of mythological poetry, legends and 13th century information. This too, despite our extremely favorable situation of being in possession of the exiting amount of theoforic place-names.
