According to the writings in The Lesser Key of Solomon, Forneus is the thirtieth spirit listed in the Goetia.
He is a Great Marquis of Hell with twenty-nine legions under his command, partly comprised of the order of Angels and Thrones, and appears as a sea monster. When summoned, he can make men well-versed in rhetoric, give him a good name, teach him foreign tongues, and make him trusted by friend and foe alike.
Forneus in the Pseudomonarchia Daemonum[]
The Pseudomonarchia daemonum, or False Monarchy of Demons, by the Dutch occultist Johann Weyer, was published as an appendix to his book titled De praestigiis daemonum, or On the Tricks of Demons, in 1577. The description of Forneus from the Pseudomonarchia daemonum is as follows:
| “ | Forneus is a great marquesse, like unto a monster of the sea, he maketh men woondeffull in rhetorike, he adorneth a man with a good name, and the knowledge of toongs, and maketh one beloved as well of foes as freends: there are under him nine and twentie legions, of the order partlie of thrones, and partlie of angels.[1] | ” |
Forneus in the Lemegeton Clavicula Salomonis (Ars Goetia)[]
The Lemegeton Clavicula Salomonis or Lesser Key of Solomon is an anonymously written book of demonology that is believed to have been complied sometime during the 17th century CE. The work is divided into five books, the first of which, known as the Ars Goetia, lists 72 demons. The Ars Goetia is heavily based off of Johann Weyer's Pseudomonarchia daemonum.
In 1904, the British occultist and founder of the religion of Thelema, Aleister Crowley, published a version of the Lesser Key of Solomon which was translated by another British occultist, Samuel Liddell MacGregor Mathers, and contained additional invocations added by Crowley. The Ars Goetia's passage on Forneus from the 1904 version is as follows:
| “ | FORNEUS. - The Thirtieth Spirit is Forneus. He is a Mighty and Great Marquis, and appeareth in the Form of a Great Sea-Monster. He teacheth, and maketh men wonderfully knowing in the Art of Rhetoric. He causeth men to have a Good Name, and to have the knowledge and understanding of Tongues. He maketh one to be beloved of his Foes as well as of his Friends. He governeth 29 Legions of Spirits, partly of the Order of Thrones, and partly of that of Angels. His Seal is this, which wear thou, etc.[2] | ” |
Forneus in the Dictionnaire Infernal[]
The Infernal Dictionary is a book of demonology written in 1818 by the French occultist Jacques Auguste Simon Collin de Plancy. The entry for Forneus is as follows:
| “ | Forneus, infernal marquis, like a sea monster. He instructs man in the highest matters, does good to his friends and harm to his enemies; he has under his power twenty-nine legions of Thrones and Angels.[3] | ” |
