Scythian Christian soldier who distinguished himself against the barbarian invaders of the Roman empire, and gained the notice of Decius. However, he refused to sacrifice to the pagan god Artemis, and so was tortured and executed. Some versions of his story include angelic visions and messages received in dreams, but his being a soldier and martyr is all we really know.
