Bust of Augustus, marble, Sime, Namurt. From the Wikipedia: Gaius Julius Caesar Augustus (23 September 63 BC – 19 August AD 14), was the first emperor of the Roman Empire, which he ruled alone from 31 BC until his death in AD 14. Born Gaius Octavius Thurinus, he was adopted by his great-uncle Gaius Julius Caesar in 44 BC, and between then and 31 BC was officially named Gaius Julius Caesar. In 27 BC the Senate awarded him the honorific Augustus ("the revered one"), and thus consequently he was Gaius Julius Caesar Augustus.[note 2] Because of the various names he bore, it is common to call him Octavius when referring to events between 63 and 44 BC, Octavian (or Octavianus) when referring to events between 44 and 27 BC, and Augustus when referring to events after 27 BC. In Greek sources, Augustus is known as Ὀκτάβιος (Octavius), Καῖσαρ (Caesar), Αὔγουστος (Augustus), or Σεβαστός (Sebastos), depending on context.
