The title word “Demotic” isn’t a typo of demonic: That material is Coptic. The illustrated main corpus is a collection of 2nd-century B.C.E. to 5th-century C.E. Egypto-Greco-Roman magical spells, rituals, and invocations from ancient papyrus spellbooks, many of them found in the tomb of a magic man in Thebes. Also known as the Papyri Graecae Magicae, or PGM.
