Miles Gloriosus (literally, “braggart-soldier”, in Latin) is a stock character of a boastful soldier from the comic theatre of ancient Rome, and variations on this character have appeared in drama and fiction ever since.[2] The character derives from the alazṓn or “braggart” of the Greek Old Comedy (e.g. Aristophanes).
