Marchosias

right|250px|thumb|Marchosias appears as a fire-spitting Chimera (mythology)|chimeric wolf with the wings of a griffon and the tail of a serpent. In demonology, Marchosias is a great and mighty Marquis of Hell, commanding thirty legions of demons. In the Ars Goetia, the first book of The Lesser Key of Solomon (17th century), he is depicted as a wolf with griffin wings and a serpent's tail, spewing fire from his mouth. At the request of the magician, he may take the form of a man. He is a strong fighter, gives true answers to all questions, and is very faithful to the magician in following his commands. Before his fall, he belonged to the angelic order of Dominations (or Dominions), and when he was bound by Solomon, he told him that after 1,200 years, he hoped to return to Heaven ("unto the Seventh Throne").

In the Pseudomonarchia Daemonum (1577) of Johann Weyer, the demon is called Marchocias, and his description is much the same as that given in the Goetia except that his gender when appearing as a wolf is female ("a cruel she-wolf") and spewing forth "I cannot tell what" from his mouth. He likewise hopes to eventually return to the Seventh Throne, but is "deceived in that hope."
