Sestertius in the context of "IMPERATOR"

Pietas (Classical Latin: [ˈpiɛtaːs]), translated variously as "duty", "religiosity" or "religious behavior", "loyalty", "devotion", or "filial piety" (English "piety" derives from the Latin), was one of the chief virtues among the ancient Romans. It was the distinguishing virtue of the founding hero Aeneas, who is often given the adjectival epithet pius ("religious") throughout Virgil's epic Aeneid. The sacred nature of pietas was embodied by the divine personification Pietas, a goddess often pictured on Roman coins. The Greek equivalent is eusebeia (εὐσέβεια).

Cicero defined pietas as the virtue "which admonishes us to do our duty to our country or our parents or other blood relations." The man who possessed pietas "performed all his duties towards the deity and his fellow human beings fully and in every respect," as the 19th-century classical scholar Georg Wissowa described it. Cicero suggests people should have awareness of their own honor and must always attempt to raise the honor of others with dignified praise. Furthermore, praise, admiration, and honored actions must be beyond all one's own desires, and actions and words must be chosen with respect to friends, colleagues, family, or blood relations. Cicero describes youth in the pursuit of honour: “How they yearn for praise! What labours will they not undertake to stand fast among their peers! How will they remember those who have shown them kindness and how eager to repay it!”

The title of imperator (/ˌɪmpəˈrɑːtər/ im-pə-RAH-tər) originally meant the rough equivalent of commander under the Roman Republic. Later, it became a part of the titulature of the Roman Emperors as their praenomen. The Roman emperors generally based their authority on multiple titles and positions, rather than preferring any single title. Nevertheless, imperator was used relatively consistently as an element of a Roman ruler's title throughout the Principate and the later Roman Empire. It was abbreviated to "IMP" in inscriptions. The word derives from the stem of the verb imperare, meaning 'to order, to command'. The English word emperor derives from imperator via Old French: Empereür.

The aureus (pl. aurei, 'golden') was the main gold coin of ancient Rome from the 1st century BC to the early 4th century AD, when it was replaced by the solidus. This type of coin was sporadically issued during the Republic and standardized during the Empire, originally valued at 25 silver denarii and 100 sestertii. It was about the same size as the denarius, but heavier than the denarius since gold is denser than silver.

Nummus (pl. nummi) is a Latin word for various coins that was borrowed from Doric Greek noummos (νοῦμμος; Classical Greek: νόμος, nómos). Originally referring to a specific style of coin used in Greek-speaking Southern Italy, the term nummus came to be used by the Late Republic for all coins generally and particularly as a synonym for the sestertius, then the standard unit of Roman accounting, and then in Late Antiquity as the formal name of the follis. It was used in this general sense in Early Modern English but is most commonly employed by modern numismatists as a catchall term for various low-value copper coins issued by the Roman and Byzantine empires during Late Antiquity.

Forms of the term nummus also appear in various scientific names and in medical jargon for coin-shaped species, structures, and disorders.

Legio V Macedonica (the Fifth Macedonian Legion) was a Roman legion. It was established in 43 BC by consul Gaius Vibius Pansa Caetronianus and Gaius Julius Caesar Octavianus (later known as the Emperor Augustus). and based in the Balkan provinces of Macedonia, Moesia and Dacia. In the Notitia Dignitatum records from beginning of the fifth century, the legion was still stationed in Dacia, with detachments stationed in the east and Egypt.

The last known evidence shows the legion, or detachments from it, stationed in Egypt in the seventh century one or two years before the Islamic conquest of Egypt. It is often assumed that the legion fought in this war and was destroyed, although it is uncertain whether detachments or the whole legion were in Egypt, and there is no further evidence of the legion's eventual fate.

In ancient Roman religion, Annona (Latin annōna “corn, grain; means of subsistence”, from annus "year") is the divine personification of the grain supply to the city of Rome. She is closely connected to the goddess Ceres, with whom she is often depicted in art.

Annona, often as Annona Augusti, was a creation of Imperial religious propaganda, manifested in iconography and cult practice. She is presented as a theophany of the emperor's power to care for his people through the provision of grain. Annona thus lacked narrative mythology or a tradition of devotion in the Roman Republic, but once established as part of Imperial cult, she was the recipient of dedications and votive offerings from private individuals motivated by gratitude or the seeking of favor.

Legio XIII Gemina, in English the 13th "Twin" Legion was a legion of the Republican, and later Imperial, Roman Army. It was one of Julius Caesar's key units in Gaul and in the civil war, and was the legion with which he crossed the Rubicon in January, perhaps on 10 January, in 49 BC. The legion appears to have still been in existence in the 5th century AD. Its symbol was the lion.
