The Shadow Over Innsmouth - Inspiration

Inspiration

Robert M. Price cites two works as literary sources for The Shadow Over Innsmouth: Robert W. Chambers' "The Harbor-Master" and Irvin S. Cobb's "Fishhead". Chambers' story concerns the discovery of "the remnants of the last race of amphibious human beings", living in a five-mile deep chasm just off the Atlantic coast. The creature of the title is described as "a man with round, fixed, fishy eyes, and soft, slaty skin. But the horror of the thing were the two gills that swelled and relaxed spasmodically."

Lovecraft was evidently impressed by this tale, writing in a letter to Frank Belknap Long: "God! The Harbour-Master!!!"

"Fishhead" is the story of a "human monstrosity" with an uncanny resemblance to a fish:

His skull sloped back so abruptly that he could hardly be said to have a forehead at all; his chin slanted off right into nothing. His eyes were small and round with shallow, glazed, pink-yellow pupils, and they were set wide apart on his head, and they were unwinking and staring, like a fish's eyes.

Lovecraft, in "Supernatural Horror in Literature", called Cobb's story "banefully effective in its portrayal of unnatural affinities between a hybrid idiot and the strange fish of an isolated lake".

Price notes that Fishhead, as the "son of a Negro father and a half-breed Indian mother", "embodies unambiguously the basic premise of 'The Shadow Over Innsmouth'.... This, of course, is really what Lovecraft found revolting in the idea of interracial marriage...the subtextual hook of different ethnic races mating and 'polluting' the gene pool."

Price points out the resemblance in names between the Deep One city of Y'ha-nthlei and Yoharneth-Lahai, a fictional deity in Lord Dunsany's The Gods of Pegana who "sendeth little dreams out of Pegana to please the people of Earth"—a precursor to Lovecraft's fictional deity Cthulhu, who sends less pleasant dreams from R'lyeh.

The description of the Deep Ones also has some similarities with the sea creature mentioned in H.G. Wells' short story In the Abyss (1896); "Two large and protruding eyes projected from sockets in chameleon fashion, and it had a broad reptilian mouth with horny lips beneath its little nostrils. In the position of the ears were two huge gill-covers, and out of these floated a branching tree of coralline filaments, almost like the tree-like gills that very young rays and sharks possess. But the humanity of the face was not the most extraordinary thing about the creature. It was a biped; its almost globular body was poised on a tripod of two frog-like legs and a long, thick tail, and its fore limbs, which grotesquely caricatured the human hand, much as a frog’s do, carried a long shaft of bone, tipped with copper. The colour of the creature was variegated; its head, hands, and legs were purple; but its skin, which hung loosely upon it, even as clothes might do, was a phosphorescent grey."
