Origin of the baby name Sebastian

Sebastian comes from the Latin Sebastiānus, originally a geographical name meaning "from Sebaste," an ancient city in Asia Minor (modern-day Sivas in Turkey). The city's name derived from the Ancient Greek Σεβαστός, which was itself a direct translation of the Roman title Augustus, meaning "venerable" or "worthy of reverence." The name's global spread owes much to Saint Sebastian, a third-century Roman soldier martyr whose story was widely celebrated across medieval Europe.
