#Augustus
- Acta est fabula — A famous Latin aphorism literally translated as 'The play has been acted' or 'The story is finished'. In ancient Roman theater, this structural phrase was pronounced at the end of performances to announce to the audience that the play was over and that they could leave. Existentially, the expression is used metaphorically to mark the end of an important stage, the definitive failure of a plan, or the end of life (historically attributed as the last words of Emperor Augustus).
- Actium — The historical name of a promontory located in northwestern ancient Greece, at the entrance of the Ambracian Gulf, universally famous for the decisive naval battle of 31 BC. This structural geopolitical event marked the defeat of the fleet of Mark Antony and Cleopatra by Octavian, leading to the end of the Roman Republic and the establishment of the Roman Empire.
- Ancyra — The ancient Greco-Roman name of the current city of Ankara, the capital of the Republic of Turkey. Located in the historical region of Galatia in central Anatolia, the city was a highly strategic commercial, military, and administrative hub within the Roman and Byzantine Empires, famous in historiography for the Monumentum Ancyranum, the temple preserving Emperor Augustus's official autobiography.
- Augustal — Relating to the Emperor Augustus or dedicated to his imperial cult in Ancient Rome. As a noun, it designates a member of the Roman priestly college (Sodales Augustales) composed of wealthy freedmen, tasked with celebrating and maintaining the religious honors of deified emperors.
- Augustulus — The pejorative nickname (meaning 'Little Augustus') given to Romulus Augustus, the last emperor of the Western Roman Empire (475–476). Deposed as a teenager by the Germanic chieftain Odoacer after ruling for only ten months, his fall symbolically marks the end of antiquity.
- Augustus — An honorific title with sacred meaning granted by the Roman Senate in 27 BC to Gaius Julius Caesar Octavianus, the first emperor of the Roman Empire. Subsequently, the term became his official name and the supreme title borne by all imperial monarchs.
