- "The madness and monstrosity lay in the figures in the foreground- for Pickman's morbid art was pre-eminently one of demoniac portraiture. These figures were seldom completely human, but often approached humanity in varying degree. Most of the bodies, while roughly bipedal, had a forward slumping, and a vaguely canine cast. The texture of the majority was a kind of unpleasant rubberiness."
- -H.P. Lovecraft, Pickman's Model
Ghouls are a species of cannibalistic humanoids featured in several of Lovecraft's works.
They are first depicted in the short story Pickman's Model, where the eponymous main character meets with the beings regularly to paint them in various poses and activities. It is revealed in The Dream-Quest of Unknown Kadath that Pickman is in fact a partial or full-blooded ghoul, and now resides with them in the Dreamlands.
