: : : : If she doesn't have any then I must venture to ask this: I don't really know too much about Roman Catholic values but is it possible that Tolkien made her childless to keep her "pure", so to speak, in a sense, if you know what I mean???

: : : she did. at least one, possibly more. the certain one, according to the geneologies, is celebrian (who later married elrond, i believe). also a possibility, according to one story (given in unfinished tales), is that amroth was also born of galadriel and celeborn, but since other versions contradict this, it's not stated as a fact.
: : Does anybody have any idea, why, despite the very long lives of the Elves, they did not have numerous children. Could it be that there is a connection to the reincarnation principle, wherby Elves could be born again, and maybe, if there weren't any souls around wiating to be reincarnated, there simply weren't any births?

: There is evidence to suggest that a certain amount of the parents' "spirit" (or "essence") is transfered into the child at birth. This is why Miriel died after giving birth to a son with such a fiery spirit (and this also explains why Feanor was able to sire so many children). This is one reason why the Elves slowly decay: the child is never as powerful as the parents. And the more children an Elf has, the less power each child will have.
Persia- : I am sick & tired of Elves being depicted as a fragile endangered species. I find this suggestion of devolution false. Even if many people don't believe in the Good People these days there are still plenty of them around.
