Furcas
In demonology, Furcas is a Knight of Hell, and rules 20 legions of demons. He teaches Philosophy, Astronomy, Rhetoric, Logic, Chiromancy and Pyromancy.
Furcas is depicted as a strong old man with white hair and a long white beard, who rides a horse while holding a sharp weapon.
Notably, the 1563 edition says Forcas is an alias of the demon Foras, but in the 1583 edition of Pseudomonarchia Daemonum, Forcas is established as a unique demon separate from Foras. According to a translation by Joseph H. Peterson:
The etymology of his name may be derived from the Latin word furca, meaning fork, or from Greco-Roman also meaning a sepulchre.
