The Dictionnaire Infernal is a book on demonology, describing demons organised in hierarchies. It was written by Jacques Collin de Plancy and first published in 1818. There were several editions of the book; perhaps the most famous is the 1863 edition, which included sixty-nine illustrations by Louis Le Breton depicting the appearances of several of the demons. Many but not all of these images were later used in S. L. MacGregor Mathers's edition of The Lesser Key of Solomon.

Adrammelech is an ancient Semitic god mentioned briefly by name in the Book of Kings, where he is described as a god of "Sepharvaim". Sepharvaim is commonly, but not certainly, identified with the twin cities of Sippar Yahrurum and Sippar Amnanum on the banks of the Euphrates, north of Babylon. The name Adrammelech probably translates to "Magnificent king."
