From the Latin name Sebastianus
which meant "from Sebaste". Sebaste was the name a town in Asia Minor, its name deriving from Greek σεβαστος (sebastos)
"venerable" (a translation of Latin Augustus
, the title of the Roman emperors). Saint
Sebastian was a 3rd-century Roman soldier martyred by arrows after it was discovered he was a Christian. Due to the saint's popularity, the name came into general use in medieval Europe, especially in Spain and France. It was also borne by a 16th-century king of Portugal who died in a crusade against Morocco.
