The story
Sebastian begins with a place and an imperial title. The Latin Sebastianus meant a person from Sebaste, a city whose Greek name came from sebastos, venerable, the Greek equivalent of Augustus. Saint Sebastian gave the name its most enduring image. According to tradition, Roman soldiers shot him with arrows and left him for dead; he survived that first execution, returned to confront the emperor, and was killed later. Renaissance artists repeatedly painted the arrow scene, turning one episode into an icon of endurance. The name then moved into very different worlds. Johann Sebastian Bach placed it at the center of musical history, while Disney's Sebastian the crab brought wit, worry, and calypso to The Little Mermaid. Sebastián in Spanish and Sebastião in Portuguese keep their own accents and rhythms. Few names can travel from an ancient city to a cathedral, a concert hall, and an animated reef without feeling like a costume.
