I was thinking especially of the three writers' reading outside the customary bounds of genre fiction. Often, a frequent reader of Tolkien, Lewis, and Lovecraft will have discovered some of the genre writers that they liked, already on his or her own. But often people who often return to these writers don't go on to explore non-genre authors whom they enjoyed, giving their reading experience a narrowness that their favorite authors didn't have.
Unquestionably. However, my citing of the above includes (though it may not be apparent) information of that nature, if not necessarily selections from. (Though Price did also include a volume of selections from Helena Blavatsky for her suggestiveness in relationship to Lovecraft.) Nearly all of these talk, at least, not only about the genre-related stories, but other works which also played a part in the development of this or that in the particular writer's work. For instance Price, being also a biblical scholar, brings a fair amount of this into his discussions, generally with specific references as well. How much of this has been done with the Tolkien or Lewis aspects, I'm not really aware.
Of course, few indeed will be the readers who can approach the breadth and depth, as readers, of so passionate a reader as Lewis. But then that's part of the pleasure of reading about what these writers read -- one's always getting leads for books and authors to try.
Certainly this is one of the joys (for me) of reading HPL. As Bloch famously said of him, "Lovecraft was my university", because he served as the gateway to discovering so many other writers and subjects which broadened perspectives and interests.
And that reading experience can have a good effect on one's rereading of the favorite authors. I should think that someone who has read around in Tolkien's books -- the Saga of the Volsungs, the Kalevala as you note, Sir Gawain and the Green Knight, Beowulf, other medieval works -- will read Hobbit and LOTR differently than someone who can read Tolkien's books only over against the reading of William Morris, Lord Dunsany, E. R. Eddison, etc. You would be better placed than I, JD, to point out the parallel case for HPL, but I would assume that the reader who knows not only Poe but some of HPL's 18th-century favorites, and not just Gothic writers but writers like Swift, Samuel Johnson, Addison, etc. would be able to tune in to things HPL was doing as writer in a way that would not be possible for someone whose reading other than HPL is restricted to genre favorites known to HPL (Hodgson, Bierce, et al.) and peers and successors.
Likewise, the fact of having read a lot in these favorite fantasists can enhance one's enjoyment of authors whom they relished. I am grateful for the fact that when the time came for me to read one of CSL's favorite books -- Edmund Spenser's Faerie Queene -- I did so as one already conditioned to enjoy it by having read the Narnian books (which in important ways are kind of Spenserian tales for children) as well as Lewis's writings about the FQ.
What a pleasure it is, to enjoy the Kalevala in Tolkien (e.g. in Tolkien's story of Tύrin) and, as it were, the Tolkien in the Kalevala.
I wonder if, in some of HPL's writings, the undertone is the rhythm of some non-genre writing, with the surface "melody" of the prose being played off against it. Does that make sense? or at least if he was feelings his way towards something like that? But at any rate it might be worth someone's while to take a non-genre author, Charles Lamb, whom HPL clearly had read, and to enjoy his writing for its own sake, and then also to detect the Lamb in some of HPL and, as it were, the HPL in, say, "Witches and Other Night-Fears."
That essay I did for Dr. Waugh's anthology,
Lovecraft and Influence, was on the influence of the Augustan writers on HPL's work, and went far beyond the obvious connections, studying also influence on themes, developments of themes, manner, techniques, etc. Though many feel their influence was detrimental, I have to disagree. His (seemingly)* slavish imitation of their form metrically was certainly a mistake as far as his own poetic development goes, but even the influence of the poets was, I think, largely positive in many other ways. For instance, who (other than you, in "Arthur Jermyn was a Yahoo") would have picked up on the relationship between Dean Swift's
Gulliver's Travels and HPL; yet the Dean's influence is most decidedly there, in a variety of ways, and not only this famous example, but even several of his more obscure works.
One thing which helps with this sort of thing enormously, of course, is
Lovecraft's Library: A Catalogue, which was re-released in a revised edition in 2012. While not covering everything he had in his library (a goodly portion of which was dispersed before a catalogue was made, and even in his letters not all titles or specific editions are given), nonetheless it provides information on over 1000 titles, in various fields, with references for those interested. A genuine goldmine for scholars as well as interested lay readers. As a result of consultation between this and the annotated edition(s) of
Supernatural Horror in Literature I have, whenever possible, picked up and referred specifically to editions owned by Lovecraft in my own work....
A great deal of my own reading since the publication of CSL's letters to his (almost) lifelong friend Arthur Greeves, around 1980, has been following up on Lewis's infectious references to his reading. This has led me to innumerable hours of enjoyment in books I might otherwise not have read, both "classics" like Walter Scott and obscurities such as Alexander Kinglake and Lord Dufferin (travel writers).
Yes, I've long had the same sort of experience as a result of reading HPL; originally the scattered references in his fiction (leading me to, say, Mather's
Wonders of the Invisible World or
Magnalia Christi Americana), then later his references in his letters (there are numerous discussions of his readings in various fields throughout his correspondence), and eventually his essays for the amateur press, both as critic and editorially, as well as in his controversies with other members. I even tracked down a copy of Gertrude Selwyn Kimball's
Providence in Colonial Times (1912), which he did not own, but which he did read his way through at the Providence Public Library (it was in the library-use-only reference section), and which had much influence on things he included in, say,
The Case of Charles Dexter Ward. (As an interesting little coincidence, this was published by Houghton Mifflin, which also published Tolkien in American hardcover.) So yes, I can definitely sympathize with your reaction there.
As I say, I've not followed up on the Tolkienian relationships quite so much, but I'm glad they're being put out there in such a way as to facilitate those who are interested. As for
The Faerie Queene... I hadn't been aware of that being such a favorite (or if I had been, I'd forgotten) of Lewis', but it doesn't at all surprise me given his comments on LotR; and for myself, with the exception of a handful of pages which I found somewhat dullish, I've always thoroughly enjoyed that work myself, having read it entire three times, and will in part several times over. Interestingly, though, my reading of this one initially came about through its connection to the Pratt/de Camp novel,
The Iron Tower....
*People tend to overlook how consciously HPL imitated these things, often with tongue-in-cheek. This is understandable, as we are only now, through biographical data, becoming aware of how many of his "serious" pastoral poems are actual parodies or pasquinades of his friends, his influences, himself, or various other matters. Few indeed are those which are genuinely pastorals in fact rather than in name only.
