I have just finished reading Jaan Puhvel's "Comparative Mythology" and Bruce Lincoln's "Death, War and Sacrifice" and found both to be extremely satisfying reads, especially in that they take a specific theme (e.g. "The Ferryman of the Dead" or "Fire in Water") and explore it by comparing the mythical data of various indo-european religions. I am now looking for books in this vein. My mind goes to Georges Dumézil but I'm afraid that some of his ideas might be too outdated. If not, what would be a good book to approach his works?
Also, since my interest in the subject started with Norse mythology, I would prefer books in which Germanic myth is included in the comparative study (i.e. preferably not books focusing on just Greek/Roman or Indian/Iranian parallels).
Thank you in advance for the recommendations.
