Constantine's victory was seen by Christians not only as a military victory, but as a victory of Christ over those who would persecute the new faith. After this point, we begin to see in Christian art the Greek letters "IC" (Jesus) "XC" (Christ) "" ("is victorious, conquers") added to depictions of the cross. The meaning is that, through the cross, Jesus Christ is victorious over sin and death. It was an ancient custom for emblems of victory to be placed in temples. Thus, after the legalization of Christianity, banners began to be placed in Christian churches.
