Today would be HPL's 126th birthday. Here's a birthday remembrance poem Clark Ashton Smith wrote about Lovecraft after the Old Gent died.
That is actually just an excerpt from the poem that CAS wrote on 31 March 1937:
TO HOWARD PHILLIPS LOVECRAFT Lover of hills and fields and towns antique, How hast thou wandered hence On ways not found before, Beyond the dawnward spires of Providence? Hast thou gone forth to seek Some older bourn than these— Some Arkham of the prime and central wizardries? Or, with familiar felidae, Dost now some new and secret wood explore, A little past the senses' farther wall— Where spring and sunset charm the eternal path From Earth to ether in dimensions nemoral? Or has the Silver Key Opened perchance for thee Wonders and dreams and worlds ulterior? Hast thou gone home to Ulthar or to Pnath? Has the high king who reigns in dim Kadath Called back his courtly, sage ambassador? Or darkling Cthulhu sent The sign which makes thee now a councilor Within that foundered fortress of the deep Where the Old Ones stir in sleep Till mighty temblors shake their slumbering continent?
Lo! in this little interim of days How far thy feet are sped Upon the fabulous and mooted ways Where walk the mythic dead! For us the grief, for us the mystery. . . . And yet thou art not gone Nor given wholly unto dream and dust: For, even upon This lonely western hill of Averoigne Thy flesh had never visited, I meet some wise and sentient wraith of thee, Some undeparting presence, gracious and august. More luminous for thee the vernal grass, More magically dark the Druid stone, And in the mind thou art forever shown As in a magic glass; And from the spirit's page thy runes can never pass.
HPL was a big fan of the term "cyclopean". Here's an article listing examples where Lovecraft used the term and then some "real world" examples. As noted in the comments, West Mill Tor is a natural formation and Saksayhuaman isn't technically "cyclopean", though more likely what HPL really meant to convey.
'...ever since I read the Arabian Nights at the age of five. In those days I used to dress up in a turban, burnt-cork a beard on my face, and call myself by the synthetic name (Allah only knows where I got it!) of Abdul Alhazred - which I later revived, in memory of old times, to confer on the hypothetical author of the hypothetical Necronomicon! But I never carried Orientalism as far as our fellow W.T contributor E. Hoffman Price, who (so Wright tells me) has travelled in the East and is familiar with the Arabic language.'
It's good overall, but the two quotes below caught my eye. If one didn't know better, you might almost think that Fossemo was talking about REH's Conan yarns. As I've said many times before, HPL's and Howard's protagonists inhabit the same universe, but their reactions to that universe are (sometimes) different.
When the master of the ghost story M.R. James read Lovecraft’s essay “Supernatural Horror in Literature”, he did not make out the deep meaning of the term “cosmic” and naively ended up by ridiculing it to a friend of his. James makes a sensational mistake, for he does not realize that adjective is the access key to the core of the fantastic literature where man must often face, with his own might only, a chaotic world and, for this, unlikely to be understood by human rationality.
All life is struggle and combat—itself a disproof of divinity—and in this fray an organism fights both its fellows and its surroundings. For such beasts neither divine plan nor ontological void exists, but only an instinctive activity and necessary will that becomes a violent war far from the least moral concept of good or evil, since it occurs for the preservation and victory of the stronger species on the weaker one. In the short novel “At the Mountains of Madness” the “Old Ones” are defeated by the ruthless “Shoggoths”. In the world it is not important whether an action is “good” or “evil”, but it is important to protect the existence and the sovereignty of the winning species. Fight and death are, for Lovecraft, completely obvious and natural conditions.
