Mammon Mammon  - a fallen angel now ruling in Hell as one of the arch-demons and prince of the tempters.  In De Plancy, Dictionnaire Infernal, Mammon is certified as Hell's ambassador to England.  He is equated with Lucifer, Satan, Beelzebub, and even with Nebuchadnezzar.  Mammon is the demon of avarice. The medieval notion was that Mammon was a Syrian god.  Matthew 6:24 and Luke 16:13 speak of Mammon as a power hostile to God.  He is pictured in Barrett, The Magus, and mentioned in Paradise Lost I, 678-681:  "Mammon led them on/Mammon, the least erected Spirit that fell/from heav'n, e'n in heav'n his looks and thoughts were always Downward bent."
