Christian mythology: the Four Horsemen of the Apocalypse
When the time of the Last Judgement comes, four riders of the divine Apocalypse shall be summoned and the Earth will tremble beneath the hooves of their mighty horses. Pestilence will come riding on his white horse, purefying the mortal flesh of all sin with his scorching breath. War will be perched atop his fiery charger, laying siege to all mortal armies, drawing blood and cries for mercy. Famine will thunder to the scene of carnage on his black steed, weighing all of the sins, creating a great hunger for absolution. And in the end, on his pale horse, Death will silently march on after the performance of his brothers has reached its end. The Grim Reaper will collect the dead and their tears, and replace them with hope. This shall spell the beginning of a new dawn.
Now I watched when the Lamb opened one of the seven seals, and I heard one of the four living creatures say with a voice like thunder, “Come!” And I looked, and behold, a white horse! And its rider had a bow, and a crown was given to him, and he came out conquering, and to conquer. (Revelation 6: 1-3)
