Goetia – S. L. MacGregor Mathers (1904) (quoted)
The Thirty-fifth Spirit is Marchosias. He is a Great and Mighty Marquis, appearing at first in the Form of a Wolf18 having Gryphon’s Wings, and a Serpent’s Tail, and Vomiting Fire out of his mouth. But after a time, at the command of the Exorcist he putteth on the Shape of a Man. And he is a strong fighter. He was of the Order of Dominations. He governeth 30 Legions of Spirits. He told his Chief, who was Solomon, that after 1,200 years he had hopes to return unto the Seventh Throne. And his Seal is this, to be made and worn as a Lamen, etc.
Pseudomonarchia daemonum – Johann Wier (1583) (quoted)
Marchosias is a great marquesse, he sheweth himselfe in the shape of a cruell shee woolfe, with a griphens wings, with a serpents taile, and spetting I cannot tell what out of his mouth. When he is in a mans shape, he is an excellent fighter, he answereth all questions trulie, he is faithfull in all the conjurors businesse, he was of the order of dominations, under him are thirtie legions: he hopeth after 1200 yeares to returne to the seventh throne, but he is deceived in that hope.
Dictionnaire Infernal – Collin de Plancy (1863) (paraphrased)
A great marquis of hell who commands 30 legions, Marchocias appears as a she-wolf with griffin wings and a serpent’s tail, and spit flames. In human form, Marchocias appears as a grand soldier. He obeys exorcists and the domination of angels.
