Dantalion (Dantaylion in Rudd’s variant) is the seventy-first demon in the demonological grimoire the Lesser Key of Solomon.
He is ranked as a duke who rules 36 legions of spirits, and described as a book-carrying man with multiple faces of varying genders. The powers attributed to him include teaching any art or science, causing love, and showing visions from anywhere in the world. Sloane MS 3824 mentions Dantalion in an invocation in “An Experiment to Obtain your Desire,” as well as in the “Experiment of Bleth,” where he is attributed with teaching various subjects, exposing secrets, mind control (including love magic), and creating an illusionary image of any person’s face. According to Rudd, Dantalion is opposed by the Shemhamphorasch angel Haiaiel.
