Hell I just lost a post links and all
Adore Bored of the Rings BTW! :twisted:
Most fantasy writers borrow heavily from mythology of various kinds and you could argue very convincingly that there are no new stories 'cos the Greeks already defined the lot
Middle Earth as a whole has Atlantean (ocean-consumed cultures), Celtic, Saxon, Greek philosophic and even Egyptian motifs (the grand architectual feats of the men of Westernesse like the Argonath and Orthanc) as well as Norse themes and others less familar
With Tolkien the bulk of his writing on Middle Earth was for purely academic development - his hobby in effect, but a lucrative one to some extent. The Hobbit and LotR were a result of an academic challenge between him and C S Lewis to write a publishable book about time travel and space travel respectively (
not so much Narnia, but The Cosmic Trilogy - Lewis was a very biased Christian zealot
) and both of them cheated!
They, with their chums in their intellectual club The Inklings (HQ the
Lamb and Flag in Oxford - The Prof liked his beer, tobacco and forest mushrooms in that order and made himself the template for hobbits and Tom Bombadil) kind of invented and formed 'mythopoeic' literature which is summed up in Tolkien's poem Mythopoeia (The wiki links are warped somehow - see
mythopoeia in the wiki search anyway) penned as an ironic slap at Lewis who had very differing ideas about the genre. Tolkien's real interest was in ancient language however and he cobbled together about 4 distinct 'tongues' using elements from Welsh, Old Saxon and Gothic sources to the extent that the elven 'language' Sindarin is actually a working language and 'spoken' today and others keep philologists bedazzled and busy - see
this site for Sindarin.
I think Terry and the Prof would have got along like a house on fire
