The Four Horsemen of the Apocalypse are described in the last book of the New Testament of the Bible, the Book of Revelation. It tells of a “scroll’ in God’s right hand that is sealed with seven seals”. The Lamb of God Judah (Jesus Christ) opens the first four of the seven seals, which summons forth four beings that ride out on white, red, black, and pale horses.
Some interpretations differ, the four riders are seen as symbolizing Pestilence, War, Famine & Death, respectively.
The Christian apocalyptic vision is that the four horsemen are to set a divine apocalypse upon the world as harbingers of the Last Judgment.
