“I looked, and there was a white horse! Its rider had a bow…and he came out conquering and to conquer. When he opened the second seal…out came another horse, bright red; it’s rider was permitted to take peace from the earth, so that people would slaughter one another…I looked, and there was a black horse! It’s rider held a pair of scales in his hand…When he opened the fourth seal…I looked and there was a pale green horse! Its rider’s name was Death.”  - The Book of Revelations 6:1-8
