I also feel like
Gandalf is influenced by the archetype of Merlin, although I recently came across a notation in an annotated (either The
Hobbit, or
The Lord of the Rings Reader's Guide) that
Tolkien was thinking more along the lines of wandering one-eyed Odin, disguised in a cloak and hat...which really quite surprised me. I didn't follow through and check the source of that particular annotation, but since it's still a new way of thinking about Gandalf, I've spent the past couple weeks mulling it over.
Without meaning to sound too critical of JRR Tolkien; I kind of feel like he missed a trick there, with King Arthur. In my own explorations of Arthurian literature, it seems to me that aspects of the overall story, combined with a less strict academic fussiness about creativity during the centuries that the Arthurian legends developed has given Arthuriana a lot of life. By that I mean, they didn't conceptualize plagiary the way we do, so many literary
artists would take
materials and translate them, but re-work them with their own spin, add new characters, change the family
trees around, ect. This has lead to many iterations of the overall King Arthur story.
The trick that Tolkien may have missed is that Arthur does keep coming back, in spirit. Over and over again. He comes back in the next iteration of the the legends. Geoffrey of Monmouth did his influential outline, then Chretian de Troyes zoomed in on individual knights adventures and helped bring emphasis to Launcelot and Percival as important players, then Robert de Boron zoomed out again; then French Vulgate and post-Vugate re-told it starting with an emphasis on Launcelot, which Sir Thomas Malory then translated and gave his own spin and emphasis.
At some point one of these
authors came up with the idea that Arthur was injured, possibly fatally but possibly not...so he goes to Avalon, where he is mystically healed; but not without transforming into a different form. One of the themes is how the
Kings and the land are one; injure the king and the land becomes a wasteland. Easy jump to hand-wave that and imagine that when Arthur is injured; it is the death and end of reading/experiencing that version of the Arthurian legend (the land Arthur rules over is contained within the book you read). But readers followed the Grail quest (in some versions) which brings renewal and change, like life. And so a reader can choose to embrace the renewal that comes with change, and read a different version of the King Arthur story. The Grail and Avalon are the change threshold, the question to readers: Arthur can come back, but not unchanged: do you want to see the changed version of Arthur, and how his
realm (the next work of literature) has changed in tandem with the healing transformation he had to undergo?
I kind of feel like Tolkien's own works can be approached that way, if people would allow for it. If people would let the Legendarium be able to breath as a wellspring of inspiration. Glance past the fragmentary parts; surely a willing mind can fill in the gaps? Or maybe those gaps can be filled in by an earlier or subsequent draft that Tolkien wrote, when he re-worked a given story? I'm sure roleplaying game Gamemasters have done a little bit of that. But other authors and television writers and movie producers can never hope to adapt Tolkien's work, right? Of course; in the same way that those earlier Arthurian writer...I mean, how dare the French introduce Launcelot to Arthur's marital life. And how the later writers add that usurping Grail knight, Galahad, to upstage Percival?! No one will ever be able to do justice to Tolkien, ever ever; just like those presumptuous Medieval writers of King Arthur (to say nothing of upstarts like TH White)!
Tolkien does write broadly about the passing of
ages, and how major parts of the story of an age are setting up the people who will bring renewal.
Beren and Luthian are the beginning of a high and noble dynasty. The
Numenorean faithful are able to establish a vast kingdom in
Middle-earth after
Sauron's defeat.
Aragorn and
Arwen echo the relationship between Beren and Luthian, and they are the foundation of a potentially great new dynasty. The
Fourth Age starts with great promise, even though the
Elves fade and diminish from the realm. There is a sense of progression and renewal from the
Second Age ("A Dark Age for
men in Middle-earth") to a promising start at the beginning of the Fourth Age.
Tolkien is said to not like allegory, I guess maybe because it's too on the nose? Maybe that's why it's too much for him that King Arthur just returns in re-tellings? Aragorn and Arwen's story echoes Beren and Luthian; but it's not the same. The two stories are similar, but different, and the characters are different, so it's not as on-the-nose?
Just some rambling thoughts I had, I don't know if they make any sense though.
