 A similar figure was the Swiss magician known as Paracelsus (1493–1541), who published "Of the Supreme Mysteries of Nature", in which he emphasised the distinction between good and bad magic.A third such individual was Johann Georg Faust, upon whom several pieces of later literature were written, such as Christopher Marlowe's "Doctor Faustus", that portrayed him as consulting with demons.The idea of demonology had remained strong in the Renaissance, and several demonological grimoires were published, including "The Fourth Book of Occult Philosophy", which falsely claimed to having been authored by Agrippa, and the "Pseudomonarchia Daemonum", which listed 69 demons.
