Helen: I appreciate your "tuppence". The analogies are indeed debatable, but your main point of the location of the eucatastrophe in the Christ Myth, is apt.
Aiwendil:
Yes, but was this not because the Valar gave over their authority to Iluvatar, asking the One to intervene? How is that a eucatastrophe? Hardly an unlooked for turn if it was begged for, don't you think? Or am I getting the sinking of Numenor and the destruction of Angband mixed up? It's been a long time since I read the Sil.
