It may very well be that such a thread has already been created somewhere here, but since I can't remember seeing any I'll ask my question anyway.
Don't you think there's a resemblance between Gandalf and Odin?
I just saw a drawing on the english Wikipedia page for Odin called Odin the Wanderer that immediately made me think of Gandalf. I mean, it wouldn't be the first time Tolkien is inspired by Norse mythology...
