Dionysus was the god of the grape harvest, winemaking and wine, of ritual madness and ecstasy in Greek mythology. His name - now thought to be verified as being a theonym - in Linear B tablets as di-wo-nu-so (KH Gq 5 inscription), shows that he may have been worshipped as early as c. 1500–1100 BCE by Mycenean Greeks; other traces of the Dionysian-type cult have been found in ancient Minoan Crete.
The Four-Horsemen of the Apocalypse are described in the last book of the New Testament of the Bible, called the Book of Revelation. The chapter tells of a book or scroll in God’s right hand that is sealed with seven seals. The Lamb of God, or Lion of Judah (Jesus Christ), opens the first four of the seven seals, which summons four beings that ride out on white, red, black, and pale horses. The four riders are often seen as symbolizing Conquest or Pestilence, War, Famine, and 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.
One reading ties the four horsemen to the history of the Roman Empire. That is, they are a symbolic prophecy of the subsequent history of the empire.
