Jacques Collin de Plancy’s 1818 book Dictionnaire Infernal contained a list of demons, part of a long tradition of grimoires and demonology texts like the Pseudomonarchia Daemonum (1577) and the Lesser Key of Solomon (mid-17th century).

What made it stand out were the illustrations: the 1863 edition contained pictures of Behemoth (a bipedal elephant), Moloch (a cow-headed king), Bael (a spider with the head of a man, a frog, and a cat), and sixty-six others.
