Tolkien’s notions of transmission were constantly evolving, as were the finer points of the
Tales that make up
Silmarillion and
Akallabêth. Like Niggle, he has been called to a journey which he long foresaw but was incompletely prepared, as are we for our own departures! And like the residents of Niggle’s Parish, we are busy finishing out the many details and rougher edges he left.
Some things are solid. Those are the “canon”, the material Tolkien himself published during his lifetime. Some are “firm”, things that make the rest of the material hold together or are central to the story:
Fëanor’s betrayal of
Fingolfin and
Finarfin’s folk and his burning of the
ships;
Túrin’s failure at
Nargothrond;
Tuor’s journey to
Gondolin led by Voronwë (but not, perhaps, his route); that Elwing cast herself into the Sea wearing the Silmaril to escape the
Sons of Fëanor, and so came to
Eärendil. Others are “pretty firm”: that
Glorfindel of
Rivendell is the same person as Glorfindel of Gondolin who died fighting a
Balrog; that
Celebrimbor of Eregion was the grandson of Fëanor by
Curufin, estranged from his father in Nargothrond. Some are “preferable”, often because they better explain the canon or were Tolkien’s position when he wrote
Lord of the Rings: among those things are the idea that
Celeborn was one of the
Sindar of
Doriath instead of the Teleri of Eldamar, and that
Galadriel was the last of the leaders of the Rebellion of the
Noldor and believed her exile in
Middle-earth was permanent. And for those who argue, as do you and I, Elthir, that this last is “canon” because Tolkien published it in
Road Goes Ever On, I hasten to point out that there are many who argue that
what was written last is canon, offering the Glorfindel equivalence (among others) as evidence.
What fits best? I argue that the
Lay of Leithian must first have been an
Elvish tale:
Only the Sindar of Doriath knew the story! Only they and they alone could possibly be privy to the information, because after he fled Dorthonion,
Beren never again saw another Mortal except his own son Dior (and Dior’s children, perhaps) and the
Dwarves he and Dior fought and killed at Sarn Athrad. Dior
never met another mortal (besides his parents and his sons) except those Dwarves, and it is possible (likely, in my opinion) that neither he nor the Sindar of Doriath even realized he was not Elvish. Dior’s only surviving child was his daughter, Elwing,
Elrond’s mother, and only Elrond “remember[s] [the
Lay of Leithian] aright as it was told of old.”
The transmission? Tolkien’s last link in his feigned transmission, besides the
scribes who copied the tales (how many of these would there be, and how many translations from language to language? how many errors arose in transmission?), was
Bilbo and his
Translations from the Elvish. Bilbo’s sources were written and oral in Rivendell: they would be as close to first-hand accounts as could be attained.
Merry also consulted Rivendell for his treatise on herbs – presumably Elladan and Elrohir, along with the remaining Eldar. Then there are writings the
Hobbits – the Gardeners, Fairbairns of the
Towers,
Tooks, and Brandybucks – gathered from
Rohan and especially from
Gondor. These Gondorian writings were probably all translated from
Sindarin,
Quenya, or archaic
Adûnaic, they were necessarily transmitted by
Men, and the question then becomes that of the origins and reliability of the tales they told. Given that the Hobbits had
Translations from the Elvish at their disposal, they could check stories from Gondor against it, and assuming Bilbo’s grasp of Sindarin and Quenya was sufficient, correct any errors they encountered.
This would account for different tellings of the same tale, undoubtedly one of Tolkien’s intentions. It would then fall to critical analysis to best determine, if possible, what the original tale might have been. But of course, we are dealing with
sub-creation, rendering our debate, at some point, pointless.
If we look at real-world chronology, though,
The Adventures of Tom Bombadil precedes
The Lord of the Rings by several years:
it influenced
LotR rather than the other way round.
I plead for “
what fits best” over what-came-last and
possibly even author’s intent
if we are discussing things other than “canon” in the sense of what the author himself published during his lifetime. (And I hasten to add that I have never yet encountered a case of “best fit” versus “author’s intent”.)
