'ARMAGEDDON, a name occurring in the Authorized Version of the English Bible in Rev. xvi. 16. The Revised Version has Harmagedon. The form is commonly regarded as the Greek equivalent of the Hebrew har megiddon, the mountain district of Megiddo. The writer is describing the place where the last decisive battle was to be fought at the Day of Judgment, and Harmagedon may have been chosen as the name because the district about Megiddo had been on several occasions the scene of great battles (cf. Judg. iv. 6 ff., v. r9). It has, however, been suggested in the Zeitschrift fiir die Alttestamentliche Wissenschaft, vii. 170 (1887), that the name is for har migdo, " his fruitful mountain" - the mountain land of Israel. Prof. Cheyne (Encyc. Bibl. s.v.) again, following suggestions of H. Gunkel, H. Zimmern and P. Jensen, compares the dragon of the Apocalypse with the Babylonian Tiamat, thinks that some myth is referred to, and finds the µay€Scov of ApµayEbwv in the divine name `YEVEAAcya5wv, a Babylonian god of the underworld. The name of the place where Tiamat was defeated by Nlarduk perhaps included that of a god of the underworld. (See Antichrist.) From the application of the word Armageddon to the great battle of the End of Time comes the use of the phrase "an Armageddon" to express any great slaughter or final conflict.
