Tolkien's final First Age timeline

[Arvegil145]

I think a far simpler and a far better answer is that the lives of the Eldar in Aman compared to Middle-earth were something like the lives of the Edain in Numenor vs those in Middle-earth: i.e. they were blessed with peace, prosperity and eternity - and as such they tended to focus every which way, from artifice/science to art to making more Eldar.

This is why I think there really isn't any rhyme or reason behind Aman births. After all, there's always another tomorrow untainted by Melkor in their eyes...


EDIT: Oh - how did you arrive at 9,258 years? Tolkien was writing my OP text in c. 1970. In our version the Bel. years last for 600 years - as they do in the 1960 comment about the 7th Age: it should probably be 9,260 years.
