Latin modification of the name of Jesus; Hristos is used in Christian churches. The oldest Christogram consists of the letters Hi (X) and Ro (P). Constantine I and his army saw a shining stavros in the sky, with the words "In hoc signo vinces" written on it, this sign means that it will lead you to victory. Until this scene, Constantine I thought he would lose the next day's battle, but after placing this mark on his army's shields, they defeated an army twice the size of his own at the Bridge of Milvio.
