Researchers disagree on the Viking Age conceptions of the god Odin. The source material is ambiguous and difficult to interpret.

According to Lassen, once the Christian way of thought has been identified, not much information is left about Odin in the old sources.
She says that while archaeologists and historians of religion may not necessarily agree with this, there is not likely to be anyone disagreeing that it is necessary to analyse the Christian additions, before starting to look into the original Viking Age conception of Odin.
“My aim with the book was to focus on the Medieval Odin figure, clarify the extent to which Christianity has shaped our ideas of heathenism and demonstrate that this calls for circumspection, but also to come up with a method that other researchers can use,” she says.
“Basing a thesis about the pre-Christian Odin on a series of elements from medieval texts about Odin presupposes an interest in whether those elements come from Christian ideas.
