what is the origin of the name sebastian
Sebastian (name) Sebastian is a given name. It comes from the Latin name Sebastianus meaning "from Sebastia", which was the ancient Greek name (Σεβάστεια) of the city now known as Sivas, located in the central portion of what is now Turkey.[1][2] The name of the city is derived from the Greek word σεβαστός (sebastos), "venerable",[3] which comes from σέβας (sebas), "awe, reverence, dread",[4] in turn from the verb σέβομαι (sebomai), "feel awe, scruple, be ashamed".[5] Sebastos was the Greek translation of the title Augustus, which was used for Roman emperors. Sebastian became a widely used name because it was the name of Saint Sebastian, a third-century Christian martyr.
