Dragon

Dragon - in Revelation 12:9, Satan is termed "the great dragon....that old serpent" who was "cast out into the earth," along with the angels who followed him.  In Psalms 91:13, "the saints shall trample the dragon under their fee."  Michael (St. Michael) is usually represented as the slayer of the dragon.  He is thus the forerunner of St. George.  In classical legend, the dragon guarded the golden apples in the garden of Hesperides.  In gnosticism, dragon is a term for the angel of dawn.  [Rf.
