Ixamyakxim: I absolutely love that he created this massive, lived in world. Even down to shaping a myth culture for said world AS WELL as a history both factual and... um epistemological? (not quite sure it's the word I'm looking for but I'll roll with it). I'm guessing what I mean is that there's a "history" as well as entire "other" history as told / experienced / passed down, which ALSO represents the chronologial and actual historical events.
I remember the first time I read the Silmarillion. I had always heard it was a bit plodding and disjointed. Oh my gosh I fell in love with it right off the bat. I mean it starts as anear Biblical genesis story, or a polytheistic creation myth. I was reminded of the stories of... (damn have to search this - the Hindu "first man" that is divided into parts to become the gods...*) And then promptly rolls into this epic retelling of ages of the major events of Middle Earth (and beyond).
I should reread this soon it's been too long.
*EDIT TO ADD
Prajapati! That was it! And while it DID (does?) exist in Hindu culture, the representation I was thinking of was actually the original Vedic one.
I agree, I really love the world he created. He has so much back story to his world and his characters, sadly most of it is in his notes and will never be released. Due to all this information some of his novels can be hard reading, I know many are put off the Silmarillion due to the amount of information it is trying to put across. But like you I loved it when I read it, and I was just thinking of the Bible like feel to the start of it.
He had quite the effect on C.S. Lewis as well, even to the extent of influencing Lewis' religion. Both I think wrote very nice worlds based on our world, although Lewis tends to put more religious undertones in his novels, but never to an extend I thought was bad like some accuse him of. In fact, I really doubt many young readers or those not up on theology would even notice due to the way he wove them into his plot.
