Spatial tripartition

Varro grouped the gods broadly into three divisions of heaven, earth, and underworld:

• di superi, the gods above or heavenly gods, whose altars were designated as altaria.^[2]
• di terrestres, "terrestrial gods," whose altars were designated as arae.
• di inferi, the gods below, that is, the gods of the underworld, infernal or chthonic gods, whose altars were foci, fire pits or specially constructed hearths.

More common is a dualistic contrast between superi and inferi.

Triads

• Archaic Triad: Jupiter, Mars, Quirinus.
• Capitoline Triad: Jupiter, Juno, Minerva.^[3]
• Plebeian or Aventine Triad: Ceres, Liber, Libera, dating to 493 BC.^[4]

Groupings of twelve

Lectisternium of 217 BC

A lectisternium is a banquet for the gods, at which they appear as images seated on couches, as if present and participating. In describing the lectisternium of the Twelve Great gods in 217 BC, the Augustan historian Livy places the deities in gender-balanced pairs:^[5]

• Jupiter–Juno
• Neptune–Minerva
• Mars–Venus
• Apollo–Diana
• Vulcan–Vesta
• Mercury–Ceres

Divine male-female complements such as these, as well as the anthropomorphic influence of Greek mythology, contributed to a tendency in Latin literature to represent the gods as "married" couples or (as in the case of Venus and Mars) lovers.^{[citation needed]}

Di Flaminales

The three deities cultivated by the major flamens were:^[8]

• Jupiter
• Mars
• Quirinus

The twelve deities attended by the minor flamens were:

• Carmentis
• Ceres
• Falacer
• Flora
• Furrina
• Palatua
• Pomona
• Portunus
• Vulcan
• Volturnus
• two other deities whose names are not known^[9]

Di selecti

Varro^[10] gives a list of twenty principal gods of Roman religion:

Sabine gods

Varro, who was himself of Sabine origin, gives a list of Sabine gods who were adopted by the Romans:^[11]

Elsewhere, Varro claims Sol Indiges – who had a sacred grove at Lavinium – as Sabine but at the same time equates him with Apollo.^[13][14] Of those listed, he writes, "several names have their roots in both languages, as trees that grow on a property line creep into both fields. Saturn, for instance, can be said to have another origin here, and so too Diana."^[c]

Varro makes various claims for Sabine origins throughout his works, some more plausible than others, and his list should not be taken at face value.^[15] But the importance of the Sabines in the early cultural formation of Rome is evidenced, for instance, by the bride abduction of the Sabine women by Romulus's men, and in the Sabine ethnicity of Numa Pompilius, second king of Rome, to whom are attributed many of Rome's religious and legal institutions.^[16] Varro says that the altars to most of these gods were established at Rome by King Tatius as the result of a vow (votum).^[d]

Indigitamenta

The indigitamenta are deities known only or primarily as a name; they may be minor entities, or epithets of major gods. Lists of deities were kept by the College of Pontiffs to assure that the correct names were invoked for public prayers. The books of the Pontiffs are lost, known only through scattered passages in Latin literature. The most extensive lists are provided by the Church Fathers who sought systematically to debunk Roman religion while drawing on the theological works of Varro, also surviving only in quoted or referenced fragments. W.H. Roscher collated the standard modern list of indigitamenta,^[17] though other scholars may differ with him on some points.

Di indigetes and novensiles

The di indigetes were thought by Georg Wissowa to be Rome's indigenous deities, in contrast to the di novensides or novensiles, "newcomer gods". No ancient source, however, poses this dichotomy, which is not generally accepted among scholars of the 21st century. The meaning of the epithet indiges (singular) has no scholarly consensus, and noven may mean "nine" (novem) rather than "new".

Augustus and Augusta

Augustus, "the elevated or august one" (masculine form) is an honorific and title awarded to Octavian in recognition of his unique status, the extraordinary range of his powers, and the apparent divine approval of his principate. After his death and deification, the title was awarded to each of his successors. It also became a near ubiquitous title or honour for various minor local deities, including the Lares Augusti of local communities, and obscure provincial deities such as the North African Marazgu Augustus. This extension of an Imperial honorific to major and minor deities of Rome and her provinces is considered a ground-level feature of Imperial cult.

Augusta, the feminine form, is an honorific and title associated with the development and dissemination of Imperial cult as applied to Roman Empresses, whether living, deceased or deified as divae. The first Augusta was Livia, wife of Octavian, and the title is then shared by various state goddesses including Bona Dea, Ceres, Juno, Minerva, and Ops; by many minor or local goddesses; and by the female personifications of Imperial virtues such as Pax and Victoria.

Bonus and Bona

The epithet Bonus, "the Good," is used in Imperial ideology with abstract deities such as Bona Fortuna ("Good Fortune"), Bona Mens ("Good Thinking" or "Sound Mind"), and Bona Spes ("Valid Hope," perhaps to be translated as "Optimism"). During the Republic, the epithet may be most prominent with Bona Dea, "the Good Goddess" whose rites were celebrated by women. Bonus Eventus, "Good Outcome", was one of Varro's twelve agricultural deities, and later represented success in general.^[26]

Caelestis

From the middle Imperial period, the title Caelestis, "Heavenly" or "Celestial" is attached to several goddesses embodying aspects of a single, supreme Heavenly Goddess. ^{[citation needed]} The Dea Caelestis was identified with the constellation Virgo ("The Virgin"), who holds the divine balance of justice. In the Metamorphoses of Apuleius,^[27] the protagonist Lucius prays to the Hellenistic Egyptian goddess Isis as Regina Caeli, "Queen of Heaven", who is said to manifest also as Ceres, "the original nurturing parent"; Heavenly Venus (Venus Caelestis); the "sister of Phoebus", that is, Diana or Artemis as she is worshipped at Ephesus; or Proserpina as the triple goddess of the underworld. Juno Caelestis was the Romanised form of the Carthaginian Tanit.^[28]

Grammatically, the form Caelestis can also be a masculine word, but the equivalent function for a male deity is usually expressed through syncretization with Caelus, as in Caelus Aeternus Iuppiter, "Jupiter the Eternal Sky."

Invictus

Invictus ("Unconquered, Invincible") was in use as a divine epithet by the early 3rd century BC. In the Imperial period, it expressed the invincibility of deities embraced officially, such as Jupiter, Mars, Hercules, and Sol. On coins, calendars, and other inscriptions, Mercury, Saturn, Silvanus, Fons, Serapis, Sabazius, Apollo, and the Genius are also found as Invictus. Cicero considers it a normal epithet for Jupiter, in regard to whom it is probably a synonym for Omnipotens. It is also used in the Mithraic mysteries.^[30]

Mater and Pater

Mater ("Mother") was an honorific that respected a goddess's maternal authority and functions, and not necessarily "motherhood" per se. Early examples included Terra Mater (Mother Earth) and the Mater Larum (Mother of the Lares). Vesta, a goddess of chastity usually conceived of as a virgin, was honored as Mater. A goddess known as Stata Mater was a compital deity credited with preventing fires in the city.^[31]

From the middle Imperial era, the reigning Empress becomes Mater castrorum et senatus et patriae, the symbolic Mother of military camps, the senate, and the fatherland. The Gallic and Germanic cavalry (auxilia) of the Roman Imperial army regularly set up altars to the "Mothers of the Field" (Campestres, from campus, "field," with the title Matres or Matronae).^[32] See also Magna Mater (Great Mother) following.

Gods were called Pater ("Father") to signify their preeminence and paternal care, and the filial respect owed to them. Pater was found as an epithet of Dis, Jupiter, Mars, and Liber, among others.
