Saint Maximus († 250) was a Christian saint who was martyred by the emperor Decius for refusing to venerate busts of the deified emperors. He was tortured on the rack and by being beaten with rods, but because he would not recant, Optimus ordered him lapidated. On May 4, 250, Maximus was led outside the city walls and stoned to death. His feast day in the Roman Catholic Church is April 30.
