The Four Horsemen: Steed of War
Wikipedia wrote:When He broke the second seal, I heard the second living creature saying, “Come.” And another, a red horse, went out; and to him who sat on it, it was granted to take peace from the earth, and that men would slay one another; and a great sword was given to him...
The rider of the second horse is often taken to represent War (he is often pictured holding a sword upwards as though ready for battle) or mass slaughter. His horse's color is red (πυρρός, from πῦρ, fire); and in some translations, the colour is specifically a "fiery" red. The color red, as well as the rider's possession of a great sword, suggests blood that is to be spilled. The sword held upward by the second horseman may represent war or a declaration of war, as seen in heraldry. In military symbolism swords held upward, especially crossed swords held upward, signify war and entering into battle
