I don’t know if you know about the Tolkien – Iceland connection, but did you for example know that:

The modern fantasy mythology created by Tolkien in his works is heavily inspired by the Nordic mythology as detailed in Snorra Edda and other sagas?

That Tolkien studied old Icelandic, read the sagas in their original language and used his language knowledge in structuring the languages of his fantasy races. Icelandic was for example used for elves (which use a lot of “þ”) and in the language of their corrupted brothers the orcs. Other things such as names taken from these studies of his are also countless. The names of the dwarves in the Hobbit are for example copied straight out of Edda as detailed among other things in this article

I just thought of this again as I saw this article about the traditional Icelandic earth-bound houses..
