There is a brief mention of
Eärendil’s sailing into the South, where he found, battled, and killed
Ungoliant, but no details are provided, and even that idea might have been dropped. Somewhere (the one-volume
Fall of Gondolin perhaps?) Christopher
Tolkien remarks upon the paucity of Eärendil stories in a vein quite similar to yours.
I have this dim notion rattling around in my cranium (this is
deep mulch territory) that at some time JRRT had planned a fourth - and greatest, including in length! - of the
Great Tales, after (in M-e chronology)
Beren &
Lúthien, Children of
Húrin and Fall of Gondolin: the
Journeys of Eärendil, a lot of which would have dealt with the journeys
before Elwing joined him (in the form of a "great white bird" given her by
Ulmo as per the published Sil) with the Silmaril. There is this matter of his stating to Milton Waldman of of the publishers Collins (letter #126, a draft dated 10 March 1950) that LoTR and The Sil were about the same length (600,000 words each!!!).
Excuse me?
The published Silmarillion is about the length (with a hefty index) of TT; without the index, it's about the size of RoTK without appendices and index!
As we know (now), The Sil was very far from being a finished text like LoTR was. So even the parts that Christopher included would likely have become larger in a polished, finished version of his father's. But my guesstimate is that that would still leave a bare minimum of one third of the intended 'Silmarillion' not just an un
finished tale, but an un
started one. Did JRRT envision the Great Tale of Eärendil's voyages to take up all of that slack?? Dealing with
regions,
peoples, and occurrences that JRRT had up to that time not even wasted more than very cursory thoughts on, if that?
Assuming this having been JRRT's intention (a
huge if!) ... my only conclusion is that JRRT had seriously lost the overview of the 'Silmarillion' writings as they stood in 1950. Excusable, as they represented over 35 years of intermittent, self-contradictory (in parts) and in style widely divergent writings -
tales, poems, annals and not a little philology with daunting etymology.
