Numenor/Atlantis

[The X Phial]

In letter 154

The particular 'myth' which lies behind this tale, and the mood both of Men and Elves at this time, is the Downfall of Númenor: a special variety of the Atlantis tradition. That seems to me so fundamental to 'mythical history' – whether it has any kind of basis in real history, pace Saurat and others, is not relevant – that some version of it would have to come in.
