This portentous object is my attempt to replicate with some precision the bas-relief referred to as having been sent to good Professor Angell, in Lovecraft's "Call of Cthulhu." This relief, however, is cast in tinted plaster, rather than being formed of still-moist clay. Feel free to request the tint that most appeals to your sense of the blasphemous and arcane.
This is how the object is described in the story:
"The bas-relief was a rough rectangle less than an inch thick and about five by six inches in area; obviously of modern origin. Its designs, however, were far from modern in atmosphere and suggestion . . . [shewing] that cryptic regularity which lurks in prehistoric writing. . . . Above these apparent hieroglyphics was a figure of evident pictorial intent, though its impressionistic execution forbade a very clear idea of its nature. It seemed to be a sort of monster, or symbol representing a monster, of a form which only a diseased fancy could conceive. If I say that my somewhat extravagant imagination yielded simultaneous pictures of an octopus, a dragon, and a human caricature, I shall not be unfaithful to the spirit of the thing. A pulpy, tentacled head surmounted a grotesque and scaly body with rudimentary wings; but it was the general outline of the whole which made it most shockingly frightful. Behind the figure was a vague suggestion of a Cyclopean architectural background. "
Surely having such an object in your own possession will bring you fruitful dreams.
