The Four Horsemen of the Apocalypse are figures in the Book of Revelation in the New Testament of the Bible, a piece of apocalypse literature attributed to John of Patmos, and generally regarded as dating from about AD 95. Similar allusions are contained in the Old Testament books of Ezekiel and Zechariah, written centuries prior. Though the text only provides a name for the fourth horseman, subsequent commentary often identifies them as personifications of Conquest (Zelus), War (Ares), Famine (Limos/Fames), and Death (Mors/Thanatos).
