Religion in ancient Rome in the context of Regifugium

The Middle East, or the Near East, was one of the cradles of civilization: after the Neolithic Revolution and the adoption of agriculture, many of the world's oldest cultures and civilizations were created there. Since ancient times, the Middle East has had several lingua franca: Akkadian, Hebrew, Aramaic, Greek, and Arabic. The Sumerians, around the 5th millennium BC, were among the first to develop a civilization. By 3150 BC, Egyptian civilization unified under its first pharaoh. Mesopotamia hosted powerful empires, notably Assyria which lasted for 1,500 years. For centuries after the 7th century BC, the region was dominated by Persian powers like the Achaemenid Empire.

In the 1st century BC, the Roman Republic conquered most of the region, and its successor, the Roman Empire, that ruled from the 6th to 15th centuries AD referred to as the Byzantine Empire, grew significantly more. Roman pagan religions were replaced by Christianity in the 4th century AD. From the 3rd to 7th centuries, Rome ruled alongside the Sasanian Empire. From the 7th century, Islam spread rapidly, expanding Arab identity in the region. The Seljuk dynasty displaced Arab dominance in the 11th century, followed by the Mongol Empire in the 13th century.

The Roman deities most widely known today are those the Romans identified with Greek counterparts, integrating Greek myths, iconography, and sometimes religious practices into Roman culture, including Latin literature, Roman art, and religious life as it was experienced throughout the Roman Empire. Many of the Romans' own gods remain obscure, known only by name and sometimes function, through inscriptions and texts that are often fragmentary. This is particularly true of those gods belonging to the archaic religion of the Romans dating back to the era of kings, the so-called "religion of Numa", which was perpetuated or revived over the centuries. Some archaic deities have Italic or Etruscan counterparts, as identified both by ancient sources and by modern scholars. Throughout the Empire, the deities of peoples in the provinces were given new theological interpretations in light of functions or attributes they shared with Roman deities.

A survey of theological groups as constructed by the Romans themselves is followed by an extensive alphabetical list concluding with examples of common epithets shared by multiple divinities.

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.

An augur was a priest and official in the classical Roman world. His main role was the practice of augury, the interpretation of the will of the gods by studying events he observed within a predetermined sacred space (templum). The templum corresponded to the heavenly space above. The augur's decisions were based on what he personally saw or heard from within the templum; they included thunder, lightning and any accidental signs such as falling objects, but in particular, birdsigns; whether the birds he saw flew in groups or alone, what noises they made as they flew, the direction of flight, what kind of birds they were, how many there were, or how they fed. This practice was known as "taking the auspices". As circumstance did not always favour the convenient appearance of wild birds or weather phenomena, domesticated chickens kept for the purpose were sometimes released into the templum, where their behaviour, particularly how they fed, could be studied by the augur.

The augural ceremony and function of the augur was central to any major undertaking in Roman society – public or private – including matters of war, commerce, and religion. Augurs sought the divine will regarding any proposed course of action which might affect Rome's pax, fortuna, and salus (peace, good fortune, and well-being).

Venus (/ˈviːnəs/; Classical Latin: [ˈwɛnʊs]) is a Roman goddess whose functions encompass love, beauty, desire, sex, fertility, prosperity, and victory. In Roman mythology, she was the ancestor of the Roman people through her son, Aeneas, who survived the fall of Troy and fled to Italy. Julius Caesar claimed her as his ancestor. Venus was central to many religious festivals, and was revered in Roman religion under numerous cult titles.

The Romans adapted the myths and iconography of her Greek counterpart Aphrodite for Roman art and Latin literature. In the later classical tradition of the West, Venus became one of the most widely referenced deities of Greco-Roman mythology as the embodiment of love and sexuality. As such, she is usually depicted nude.

Neptune (Latin: Neptūnus [nɛpˈtuːnʊs]) is the god of freshwater and the sea in the Roman religion. He is the counterpart of the Greek god Poseidon. In the Greek-inspired tradition, he is a brother of Jupiter and Pluto, with whom he presides over the realms of heaven, the earthly world (including the underworld), and the seas. Salacia is his wife.

Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions. He was likely associated with freshwater springs before the sea; his festival, Neptunalia, took place on July 23, during the peak of summer when water was scarcest. Like Poseidon, he was also worshipped by the Romans as a god of horses, Neptunus equestris, who was also a patron of horse-racing.

In ancient Greek religion and mythology, Artemis (/ˈɑːrtɪmɪs/; Ancient Greek: Ἄρτεμις) is the goddess of the hunt, the wilderness, wild animals, transitions, nature, vegetation, childbirth, care of children, and chastity. In later times, she was identified with Selene, the personification of the Moon. She was often said to roam the forests and mountains, attended by her entourage of nymphs. The goddess Diana is her Roman equivalent.

In Greek tradition, Artemis is the daughter of Zeus and Leto, and twin sister of Apollo. In most accounts, the twins are the products of an extramarital liaison. For this, Zeus's wife Hera forbade Leto from giving birth anywhere on solid land. Only the island of Delos gave refuge to Leto, allowing her to give birth to her children. In one account, Artemis is born first and then proceeds to assist Leto in the birth of the second twin, Apollo.

In government and politics, inauguration is the process of swearing a person into office and thus making that person the incumbent. Such an inauguration commonly occurs through a formal ceremony or special event, which may also include an inaugural address by the new official.

The word inauguration stems from the Latin augur, which refers to the rituals of ancient Roman priests seeking to interpret if it was the will of the gods for a public official to be deemed worthy to assume office.

Hades (/ˈheɪdiːz/; Ancient Greek: ᾍδης, romanized: Hā́idēs, Attic Greek: [háːi̯dεːs], later [háːdeːs]), in the ancient Greek religion and mythology, is the god of the dead and riches and the King of the underworld, with which his name became synonymous. Hades was the eldest son of Cronus and Rhea, although this also made him the last son to be regurgitated by his father. He and his brothers, Zeus and Poseidon, defeated, overthrew, and replaced their father's generation of gods, the Titans, and claimed joint sovereignty over the cosmos. Hades received the underworld, Zeus the sky, and Poseidon the sea, with the solid earth, which was long the domain of Gaia, available to all three concurrently. In artistic depictions, Hades is typically portrayed holding a bidentand wearing his helm with Cerberus, the three-headed guard-dog of the underworld, standing at his side.

Roman-era mythographers eventually equated the Etruscan god Aita,and the Roman gods Dis Pater and Orcus, with Hades, and merged all these figures into Pluto, a Latinisation of Plouton (Ancient Greek: Πλούτων, romanized: Ploútōn), itself a euphemistic title (meaning "the rich one") often given to Hades.

The Capitoline Triad was a group of three deities who were worshipped in ancient Roman religion in an elaborate temple on Rome's Capitoline Hill (Latin Capitolium). It comprised Jupiter, Juno and Minerva. The triad held a central place in the public religion of Rome.

Juno (English: /ˈdʒuːnoʊ/ JOO-noh; Latin: Iūnō [ˈjuːnoː]) is a goddess in the ancient Roman religion, the protector and special counsellor of the state. She equates to Hera, queen of the gods in Greek mythology and a goddess of love and marriage. A daughter of Saturn and Ops, she is the sister and wife of Jupiter and the mother of Mars, Vulcan, Bellona, Lucina and Juventas. Like Hera, her sacred animal is the peacock. Her Etruscan counterpart is Uni, and she was said to also watch over the women of Rome. As the patron goddess of Rome and the Roman Empire, Juno was called Regina ("Queen") and is a member of the Capitoline Triad (Juno Capitolina), centered on the Capitoline Hill in Rome, with also includes Jupiter, and Minerva, goddess of wisdom.

Juno's own warlike aspect among the Romans is apparent in her attire. She was often shown armed and wearing a goatskin cloak. The traditional depiction of this warlike aspect was assimilated from the Greek goddess Athena, who bore a goatskin, or a goatskin shield, called the Aegis. Juno was also shown wearing a diadem.

In Roman religion, the genius (Latin: [ˈɡɛnɪ.ʊs]; pl.: genii) is the individual instance of a general divine nature that is present in every individual person, place, or thing. Much like a guardian angel, the genius would follow each man from the hour of his birth until the day he died. For women, it was the Juno spirit that would accompany each of them.

In ancient Rome, the Vestal Virgins or Vestals (Latin: Vestālēs, singular Vestālis [wɛsˈtaːlɪs]) were priestesses of Vesta, virgin goddess of Rome's sacred hearth and its flame.

The Vestals were unlike any other public priesthood. They were chosen before puberty from several suitable candidates, freed from any legal ties and obligations to their birth family, and enrolled in Vesta's priestly college of six priestesses. They were supervised by a senior vestal but chosen and governed by Rome's leading male priest, the pontifex maximus—in the Imperial era, this meant the emperor.

The Secular or Saecular Games (Ludi Saeculares) was an ancient Roman religious celebration involving sacrifices, theatrical performances, and public games (ludi). It was held irregularly in Rome for three days and nights to mark the ends of various eras (saecula) and to celebrate the beginning of the next. In particular, the Romans reckoned a saeculum as the longest possible length of human life, either 100 or 110 years in length; as such, it was used to mark various centennials, particularly anniversaries from the computed founding of Rome.

According to Roman mythology, the Secular Games began as the Tarentine Games (Ludi Tarentini) when a Sabine man called Valesius prayed for a cure for his children's illness and was supernaturally instructed to sacrifice on the Campus Martius to Dis Pater and Proserpina, deities of the underworld. Some ancient authors traced official celebrations of the Games as far back as 509 BC, but the only clearly attested celebrations under the Roman Republic took place in 249 and in the 140s BC. They involved sacrifices to the underworld gods over three consecutive nights. The Games were revived in 17 BC by Rome's first emperor Augustus, with the nocturnal sacrifices on the Campus Martius now transferred to the Moerae (fates), the Ilythiae (goddesses of childbirth), and Terra Mater ("Mother Earth"). The Games of 17 BC also introduced day-time sacrifices to Roman deities on the Capitoline and Palatine hills. Certain sacrifices were unusually specified to be performed by married women. Each sacrifice was followed by theatrical performances. Later emperors held celebrations in AD 88 and 204, after intervals of roughly 110 years. However, they were also held by Claudius in AD 47 to celebrate the 800th anniversary of Rome's foundation, which led to a second cycle of Games in 148 and 248. The Games were abandoned under later Christian emperors.

Vesta (Classical Latin: [ˈwɛs.ta]) is the virgin goddess of the hearth, home, and family in Roman religion. She was rarely depicted in human form, and was more often represented by the fire of her temple in the Forum Romanum. Entry to her temple was permitted only to her priestesses, the Vestal Virgins. Their virginity was deemed essential to Rome's survival; if found guilty of inchastity, they were buried or entombed alive. As Vesta was considered a guardian of the Roman people, her festival, the Vestalia (7–15 June), was regarded as one of the most important Roman holidays. During the Vestalia privileged matrons walked barefoot through the city to the temple, where they presented food-offerings. Such was Vesta's importance to Roman religion that following the rise of Christianity, hers was one of the last non-Christian cults still active, until it was forcibly disbanded by the Christian emperor Theodosius I in AD 391.

The myths depicting Vesta and her priestesses were few; the most notable of them were tales of miraculous impregnation of a virgin priestess by a phallus appearing in the flames of the sacred hearth — the manifestation of the goddess combined with a male supernatural being. In some Roman traditions, Rome's founders Romulus and Remus and the benevolent king Servius Tullius were conceived in this way. Vesta was among the Dii Consentes, twelve of the most honored gods in the Roman pantheon. She was the daughter of Saturn and Ops, and sister of Jupiter, Neptune, Pluto, Juno, and Ceres. Her Greek equivalent is Hestia.

In ancient Greek religion and mythology, Helios (/ˈhiːliəs, -ɒs/; Ancient Greek: Ἥλιος pronounced [hɛ̌ːlios], lit. 'Sun'; Homeric Greek: Ἠέλιος) is the god who personifies the Sun. His name is also Latinized as Helius, and he is often given the epithets Hyperion ("the one above") and Phaethon ("the shining"). Helios is often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol. The Roman Emperor Julian made Helios the central divinity of his short-lived revival of traditional Roman religious practices in the 4th century AD.

Helios figures prominently in several works of Greek mythology, poetry, and literature, in which he is often described as the son of the Titans Hyperion and Theia and brother of the goddesses Selene (the Moon) and Eos (the Dawn). Helios's most notable role in Greek mythology is the story of his mortal son Phaethon. In the Homeric epics, his most notable role is the one he plays in the Odyssey, where Odysseus's men despite his warnings impiously kill and eat Helios's sacred cattle that the god kept at Thrinacia, his sacred island. Once informed of their misdeed, Helios, in wrath, asks Zeus to punish those who wronged him, and Zeus, agreeing, strikes their ship with a thunderbolt, killing everyone except Odysseus himself, the only one who had not harmed the cattle and was allowed to live.

In ancient Roman religion, Roma was a female deity who personified the city of Rome and, more broadly, the Roman state. She was created and promoted to represent and propagate certain of Rome's ideas about itself, and to justify its rule. She was portrayed on coins, sculptures, architectural designs, and at official games and festivals. Images of Roma had elements in common with other goddesses, such as Rome's Minerva, her Greek equivalent Athena and various manifestations of Greek Tyche, who protected Greek city-states; among these, Roma stands dominant, over piled weapons that represent her conquests, and promising protection to the obedient. Her "Amazonian" iconography shows her "manly virtue" (virtus) as fierce mother of a warrior race, augmenting rather than replacing local goddesses. On some coinage of the Roman Imperial era, she is shown as a serene advisor, partner and protector of ruling emperors. In Rome, the Emperor Hadrian built and dedicated a gigantic temple to her as Roma Aeterna ("Eternal Rome"), and to Venus Felix ("Venus the Bringer of Good Fortune"), emphasising the sacred, universal and eternal nature of the empire.

Roma's official cult served to advance the propagandist message of Imperial Rome. In Roman art and coinage, she is usually depicted in military form, with helmet and weapons. In Rome's eastern provinces, she was often shown with mural crown or cornucopia, or both. Her image is rarely found in a commonplace or domestic context. Roma was probably favoured by Rome's high-status Imperial representatives abroad, rather than the Roman populace at large. She was depicted on silver cups, arches, and sculptures, including the base of the column of Antoninus Pius. She survived into the Christian period as a personification of the Roman state. Her depiction seated with a shield and spear later influenced that of Britannia, personification of Britain.

In ancient Roman religion Victoria was the deified personification of victory. She first appeared during the first Punic War, seemingly as a Romanised re-naming of Nike, the goddess of victory associated with Rome's Greek allies in the Greek mainland and in Magna Graecia. Thereafter she comes to symbolise Rome's eventual hegemony and right to rule. She is a deified abstraction, entitled to a cult. But unlike Nike, she has virtually no mythology of her own.

The vocabulary of ancient Roman religion was highly specialized. Its study affords important information about the religion, traditions and beliefs of the ancient Romans. This legacy is conspicuous in European cultural history in its influence on later juridical and religious vocabulary in Europe, particularly of the Christian Church. This glossary provides explanations of concepts as they were expressed in Latin pertaining to religious practices and beliefs, with links to articles on major topics such as priesthoods, forms of divination, and rituals.
