I've always thought of Thor as youthful and warlike, whereas I think of Zeus as old and wise. I actually thought Thor was the god of war until I just looked it up and clarified it.
What does this mean? Did the Norse view leadership through the lens of raw strength (ability to lift the hammer), whereas Greeks viewed leadership in a more managerial, orchestrational sense?
What are the other differences between the Norse and Greek pantheons, and what could they mean?
Is this even a valid method of historical inquiry?
It's not strictly speaking identical to your question, but /u/steelcan909 wrote this answer and /u/platypuskeeper wrote this answer warning of the difficulties of drawing any sort of conclusions about and from Norse mythology, due to the deceptively small size of the available corpus.
