Constantine the Great is said to have received his famous Vision of the Cross.
Constantine the Great’s Vision of the Cross is a famous episode that reportedly occurred in 312 CE, just before the decisive Battle of the Milvian Bridge. According to historical accounts, Constantine I, who would later become the first Christian emperor of Rome, experienced a vision or dream in which he saw a symbol of the cross along with a message. This vision played a crucial role in his conversion to Christianity and influenced his support for the religion throughout the Roman Empire.
The Vision of the Cross
There are two main accounts of Constantine’s vision, provided by two early Christian writers: Lactantius and Eusebius of Caesarea.
Lactantius’s Account:
Lactantius, an early Christian author, recorded a version of the vision in his work, On the Deaths of the Persecutors, written a few years after the event:
Dream Before the Battle: According to Lactantius, Constantine had a dream on the night before the Battle of the Milvian Bridge. In this dream, he was instructed to paint the Chi-Rho symbol (?) on his soldiers’ shields. This symbol, formed by the superimposed Greek letters ? (Chi) and ? (Rho), represents the first two letters of “Christ” (???????) in Greek.
In hoc signo vinces: Lactantius wrote that Constantine received a message in his dream: “In hoc signo vinces” (“In this sign, you will conquer”). This phrase indicated that victory in battle would come through the protection of the Christian God if Constantine adopted this symbol.
Eusebius’s Account:
Eusebius of Caesarea, a bishop and historian, provided a more elaborate version of the vision in his Life of Constantine, which was written later and based on Constantine’s own account of the event:
Daytime Vision of the Cross: Eusebius claimed that Constantine saw a vision in the sky while marching with his army. This vision appeared in broad daylight, with a cross of light appearing above the sun, accompanied by the words “?? ????? ????” (Greek for “In this sign, conquer”).
Interpretation of the Vision: Constantine was reportedly puzzled by this sight, and he sought further guidance. Later that night, he had a dream in which Christ appeared to him, explaining the significance of the cross symbol and instructing him to use it as a protective sign in battle.
Labarum Standard: Following this vision, Constantine ordered the creation of a military standard known as the Labarum, featuring the Chi-Rho symbol. This symbol became associated with Constantine’s army and, eventually, with Christianity itself as a military and spiritual emblem.
