In 312 AD Roman Emperor Constantine the Great, experienced a vision of the Chi Rho in the sky accompanied by the Latin phrase In hoc signo vinces ("In this sign, you will conquer") prior to the Battle of the Milvian Bridge. After winning the battle, he placed the symbol—also known as the Labarum—on his military standards and his soldiers' shields
