Mythology is stories, and stories reflect the mind of the storyteller. We acknowledge that when we talk about how a given mythological tale reflects a culture and its level of scientific and social advancement. The individuals who told the stories also projected them through their own personal lenses, not only as members of their culture but as people with internal psychology.
One of the things I learned while writing Some Say Fire, in which I retold as much of the heathen lore as I could find along with original material inserted interstitially, is that it is impossible to write objective fiction about the gods no matter how hard I try. Even though I relate to the gods either as people with personalities or as nature, when I wrote fiction about them they inevitably turned into archetypes. For example, the ways that Fireverse Odin differs from traditional Odin all turned out to be about my real life deceased father. I didn't intend to do that. I didn't even realize that until after I had enough of a draft completed to show it to someone else and my critique partner pointed it out to me; I knew I had turned my problems over to my higher power by giving them to Loki, but I hadn't realized how much that distorted all the other characters in the story.
Only after I had dealt with those issues was I able to get past them and reach the real Odin. In mythology or fairy tale, the father figure is your father, the road is your path, and the mountain is whatever obstacle you yourself must overcome. Everything turns into dream symbolism.
This same phenomenon must surely have happened when the lore that we have received in written form was first written down. The lore contained in Snorri's Edda must therefore reflect Snorri the individual as much as it reflects the lore as he had heard it in his lifetime, and as much as it reflects his culture and the times he lived in.
Fireverse Odin turned into my father and Fireverse Loki my wounded inner child because those are the personal issues I needed to resolve through my creative writing. Snorri's Odin turned into Yahweh and his Loki turned into the Devil. As a Christian with recent heathen ancestors living in the time of conversion, watching his culture be destroyed by the very thing he most passionately believed in--the Church-- resolving the cognitive dissonance between his Christian beliefs and his love of the stories of his culture must have been his greatest psychological need.
The subjectivity of story, even mythology from an oral tradition, is something to keep in mind in interpreting the lore. Some of my fellow Asatruars treat the Eddas as if they were the word of the gods. The Eddas were written by men; men have human needs, including psychological needs. The storyteller shapes the story even if he tries not to.
