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, War, Famine, and Death.
Revelation 6 tells of a book or scroll in God's right hand that is sealed with seven seals. The Lamb of God/Lion of Judah opens the first four of the seven seals, which summons four beings that ride out on white, red, black, and pale horses. All of the horsemen save for Death are portrayed as being human in appearance.
