This one I'd like to ask where the source for this can be found, just so I can verify it please? it's the kind of thing I really look for in formulating an opinion.
If I may jump in, Christopher
Tolkien stated that the Second Prophecy of
Mandos was abandoned, which need not be conflated with the idea of Túrin dealing Morgoth a death blow, even though that had appeared in this prophecy.
In his discussion of the
Valaquenta (Morgoth's Ring) Christopher Tolkien states that the text used for the end of the 1977, constructed Silmarilion [Quenta Silmarillion section anyway], shows that:
"The Second Prophecy of Mandos had now therefore definitively disappeared". Here he's referring to Tolkien's:
"if any change shall come and the Marring be amended, Manwe and Varda may know; but they have not revealed it, and it is not declared in the dooms of Mandos".
There is also Tolkien himself (Morgoth's Ring again) noting that the Second Prophecy is "now" (in revision) rather to be seen as a Numenoriean myth. Here again, Second
Prophecy of Mandos: out --
Numenorean myth: in.
But again, Christopher Tolkien never claimed that what was in the Second Prophecy had definitively been abandoned (had "definitively disappeared").
In addition, not only do we have at least one other idea about how
Arda Marred could become Arda Healed, but then we throw in the late-ish prophecy from Andreth [about Túrin] into the mix, and now we again have a
prophecy -- though not, of course, from Mandos himself . . . which makes
some folk, at least,
wonder if JRRT had taken Túrin out of the Numenorean myth!
That myth being the former prophecy of Mandos
Anyway, that's my story.
I found it in a wonderful carboard box, and so far, I'm stickin' with it!
