Subsequently Theodosius portrayed himself on his coins holding the "labarum". This standard is called a "labarum". Some argue this might be a folk etymology applied to the Latin "labarum". Beyond its derivation from Latin "labarum", the etymology of the word is unclear. Constantine's standard was known as the Labarum. This richly ornamented standard was called "labarum". As for the labarum itself, there is little evidence for its use before 317. Another one of these symbols was a labarum piercing a dragon, a serpent. It was displayed on the "labarum" military standard used by Constantine I in AD 312. The labarum is still used today by the Orthodox Church in the Sunday service.
