In Christian mythology, God has a scroll. A certain “lamb” opens the scroll, which contains seven symbolic seals. Upon opening each seal, the lamb releases the wrath of God in the form of four symbolically attired beasts who arrive atop four symbolically colored horses. The myth is an instructive affair foretelling the Last Judgment by way of an apocalypse (Greek for “lifting the veil” on something hidden from the rest of mankind).
The first horse is white, and his rider holds a bow and wears a victor’s crown. He is associated with, among other things, military conquest.
The second horse is fiery red, his rider holds a large sword and he’s all about violence and war.
The third horse is black, and his rider holds a pair of scales which represents the way bread would have been weighed back in the day and he symbolizes famine.
The fourth and final horse is pale green. His rider isn’t carrying anything, but he’s followed by Hades and is named “Death”.
In this legend, these nasty creatures in their symbolic form foretell the havoc that is to be wrecked upon mankind. While it has been the daunting task of Christian scholars to speculate and debate their return, we may consider ourselves lucky that these galloping meanies have chosen an antiquated, and relatively slow mode of transportation.
