"In an instant every moving entity was electrified; and forming at once into a ceremonial procession, the nightmare horde slithered away in quest of the sound—goat, satyr, and aegipan, incubus, succuba, and lemur, twisted toad and shapeless elemental, dog-faced howler and silent strutter in darkness—all led by the abominable naked phosphorescent thing that had squatted on the carved golden throne, and that now strode insolently bearing in its arms the glassy-eyed corpse of the corpulent old man."
H.P. Lovecraft, The Horror At Red Hook

Rossel Hope Robbins, The Encyclopedia Of Witchcraft & Demonology
