It delights me even more, though, to hear that my nameless cosmic monsters have an air of originality about them! Shapeless, unheard-of creatures are not original with me; for although Poe did not use them, they figure quite widely in minor horror-writing since his time. Usually they tend to be exaggerations of certain known life-forms such as insects, poisonous plants, protozoa, & the like, although a few writers break away wholly from terrestrial analogy & depict things as abstractly cosmic as luminous protoplasmic globes. If I have gone beyond these, it is only subtly & atmospherically—in details, & in occasional imputations of geometrical, biological, & physico-chemical properties definitely outside the realm of matter as understood by us. Most of my monsters fail altogether to satisfy my sense of the cosmic—the abnormally chromatic entity in being the only one of the lot which I take any pride in.
