The "Four Horsemen" is a symbolic representation from the Christian Bible, specifically in the Book of Revelation. They are often interpreted as figures that embody different aspects of human suffering and calamity. The four horsemen are traditionally named Conquest, War, Famine, and Death, each riding a different colored horse. Each horseman signifies a specific type of crisis. Conquest is often depicted on a white horse, representing victory and dominance. War rides a red horse, symbolizing conflict and bloodshed. Famine is associated with a black horse, indicating scarcity and hunger, while Death rides a pale horse, representing mortality and the end of life.
