Imperial cult (ancient Rome)

Augustus (plural Augusti; /ɔːˈɡʌstəs/ aw-GUST-əs, Classical Latin: [au̯ˈɡʊstʊs]; "majestic", "great" or "venerable") was the main title of the Roman emperors during Antiquity. It was given as both name and title to Gaius Julius Caesar Octavianus (often referred to simply as Augustus) in 27 BC, marking his accession as Rome's first emperor. On his death, it became an official title of his successor, and was so used by all emperors thereafter. The feminine form Augusta was used for Roman empresses and other female members of the imperial family. The masculine and feminine forms originated in the time of the Roman Republic, in connection with things considered divine or sacred in traditional Roman religion. Their use as titles for major and minor Roman deities of the Empire associated the imperial system and family with traditional Roman virtues and the divine will and may be considered a feature of the Roman imperial cult.

In Rome's Greek-speaking provinces, "Augustus" was translated as Sebastos (Σεβαστός), or Hellenised as Augoustos (Αὔγουστος); these titles continued to be used in the Byzantine Empire until the Fall of Constantinople in 1453, although they gradually lost their imperial exclusivity in favour of Basileus and Autokrator.

Ludi (Latin for "games"; plural of ludus) were public games held for the benefit and entertainment of the Roman people (populus Romanus). Ludi were held in conjunction with, or sometimes as the major feature of, Roman religious festivals, and were also presented as part of the cult of state.

The earliest ludi were horse races in the circus (ludi circenses). Animal exhibitions with mock hunts (venationes) and theatrical performances (ludi scaenici) also became part of the festivals. Because some of these entertainments are not competitive "games", ludi may also be translated more generally as "shows".

In ancient Roman religion, Concordia (means "concord" or "harmony" in Latin) is the goddess who embodies agreement in marriage and society. Her Greek equivalent is usually regarded as Harmonia, with musical harmony a metaphor for an ideal of social concord or entente in the political discourse of the Republican era. She was thus often associated with Pax ("Peace") in representing a stable society. As such, she is more closely related to the Greek concept of homonoia (likemindedness), which was also represented by a goddess.

Concordia Augusta was cultivated in the context of Imperial cult. Dedicatory inscriptions to her, on behalf of emperors and members of the imperial family, were common.

Ancient Roman temples were among the most important buildings in Roman culture, and some of the richest buildings in Roman architecture, though only a few survive in any sort of complete state. Today they remain "the most obvious symbol of Roman architecture". Their construction and maintenance was a major part of ancient Roman religion, and all towns of any importance had at least one main temple, as well as smaller shrines. The main room (cella) housed the cult image of the deity to whom the temple was dedicated, and often a table for supplementary offerings or libations and a small altar for incense. Behind the cella was a room, or rooms, used by temple attendants for storage of equipment and offerings. The ordinary worshiper rarely entered the cella, and most public ceremonies were performed outside of the cella where the sacrificial altar was located, on the portico, with a crowd gathered in the temple precinct.

The most common architectural plan had a rectangular temple raised on a high podium, with a clear front with a portico at the top of steps, and a triangular pediment above columns. The sides and rear of the building had much less architectural emphasis, and typically no entrances. There were also circular plans, generally with columns all round, and outside Italy there were many compromises with traditional local styles. The Roman form of temple developed initially from Etruscan temples, themselves influenced by the Greeks, with subsequent heavy direct influence from Greece.

Deus (Classical Latin: [ˈd̪e.ʊs], Ecclesiastical Latin: [ˈd̪ɛː.us]) is the Latin word for 'god' or 'deity'.Latin deus and dīvus ('divine') are in turn descended from Proto-Indo-European *deiwos, 'celestial' or 'shining', from the same root as *Dyēus, the reconstructed chief god of the Proto-Indo-European pantheon.

In Classical Latin, deus ("dea" in the feminine) was a general noun referring to a deity, while in technical usage a divus or diva was a figure who had become divine, such as a divinized emperor. In Late Latin, Deus came to be used mostly for the Christian God. It was inherited by the Romance languages in Galician and Portuguese Deus, Catalan and Sardinian Déu, French and Occitan Dieu, Friulian and Sicilian Diu, Italian Dio, Spanish Dios and (for the Jewish God) Ladino דייו/דיו Dio/Dyo, etc., and by the Celtic languages in Welsh Duw, and Irish and Scottish Gaelic Dia.

In ancient Roman religion, the rex sacrorum ("king of the sacred things", also sometimes rex sacrificulus) was a senatorial priesthood reserved for patricians. Although in the historical era, the pontifex maximus was the head of Roman state religion, Festus says that in the ranking of the highest Roman priests (ordo sacerdotum), the rex sacrorum was of highest prestige, followed by the flamines maiores (Flamen Dialis, Flamen Martialis, Flamen Quirinalis) and the pontifex maximus. The rex sacrorum was based in the Regia.
