The first horseman, Pestilence, rides a white horse, and is associated with infectious disease. The rider represents the Antichrist, a false depiction of a prophet. The second, War, rides a [fiery] red horse, and is often pictured holding a sword like he’s ready for mass slaughter. He represents civil war more than one of conquest. The third, Famine, rides a black horse, carrying weighing scales. Authors interpret him as the “Lord as a Law-Giver” holding Scales of Justice. The horseman’s also symbolic of the wealthy and the destructive power of the class gap of a society. The final rider, Death, rides a pale horse, is followed by Hades, and carries a scythe, as a Grim Reaper should.
The Four Horsemen of the Apocalypse, by Dante Corvus.
