Roman Religion
Religio Romana; the cult of the Roman state
c.750 BCE – c.400 CE · Classical Mediterranean · Revived / Reconstructed · Italy and the Roman empire
III. THE AXIAL AGE — c.900 – 200 BCE
How many
Extinct as a state cult; small modern reconstructionist groups (Nova Roma and others).
Who began it
No founder. Tradition credited Numa Pompilius, the legendary second king, with organising the priesthoods and calendar.
What it is for
To keep the pax deorum — the peace of the gods, a contractual state of good relations on which Rome's success depended. Religion was a department of government, not a matter of private conviction.
What it worships
The Capitoline Triad: Jupiter, Juno, Minerva. Mars, hugely important as father of Romulus. Vesta, whose hearth-fire the Vestal Virgins kept alight. Janus, Saturn, Venus, Quirinus. Household gods: the lares and penates, and the genius of the paterfamilias. Abstractions personified and given temples: Fides, Concordia, Victoria, Fortuna. From Augustus, the deified emperors.
What it holds
Roman religion is contractual and legalistic. Do ut des. Vows (vota) are formal offers: if you grant this, I will build that. Prayer formulae were recited with exact wording, and an error voided the rite and required the whole thing to be repeated. The Romans were famously willing to import gods, including by evocatio, formally inviting an enemy city's patron deity to defect to Rome before besieging it. What they punished was not wrong belief but superstitio — excessive, foreign or unauthorised practice that disturbed public order.
What it does
Animal sacrifice with strict procedure. Augury — reading the flight of birds — and haruspicy, liver-reading inherited from the Etruscans. The Sibylline Books consulted in emergencies. Priesthoods as political offices: pontifices, augurs, flamines, the Vestals, and the pontifex maximus, a title Julius Caesar held and which the popes later took over. Festivals: Saturnalia, Lupercalia, Parentalia. Triumphs. From 29 BCE, the imperial cult, which was the empire's real loyalty test.
After death
Vague, and Romans were relaxed about it. The dead become manes, collective ancestral spirits, fed at the Parentalia and Lemuria. Educated Romans were often frankly sceptical — Cicero and Pliny the Elder both write dismissively of survival, and Caesar could argue in the Senate that death ends everything without scandal. Elysium and Tartarus were literary furniture borrowed from the Greeks. The mystery religions — Isis, Mithras, Cybele, and eventually Christianity — succeeded in Rome precisely because they offered a definite and better answer where the state cult offered none.
Its texts
No scripture. Ritual manuals and priestly records (libri pontificales, Acta), the Sibylline Books, Ovid's Fasti on the festival calendar, Varro's lost antiquities, Virgil's Aeneid as a national religious epic.
Its branches
State cult; household cult; imperial cult; the imported mystery cults of Isis, Cybele and Mithras.
Of note
Rome persecuted Christians not for believing the wrong thing but for refusing to perform the civic rite. In a religion of orthopraxy, refusal to act is the only real heresy.
Its timeline
- c.753 BCE Traditional founding of Rome.
- c.700–673 BCE Numa's reforms, as tradition has it.
- 390 BCE Gauls sack Rome; the failure is blamed on neglected ritual.
- 205 BCE The Magna Mater is imported from Anatolia on Sibylline advice during the war with Hannibal.
- 186 BCE The Senate violently suppresses the Bacchanalia — thousands executed. The template for later persecutions.
- 44 BCE Julius Caesar deified after death.
- 29 BCE onward Augustus restores temples and priesthoods and establishes the imperial cult.
- 64 CE Nero's persecution of Christians after the fire.
- 249–251, 303–311 CE Empire-wide persecutions under Decius and Diocletian, both organised around a requirement to sacrifice.
- 313 CE Edict of Milan legalises Christianity.
- 380 CE Edict of Thessalonica makes Nicene Christianity the state religion.
- 382 CE The Altar of Victory removed from the Senate house; Symmachus appeals for tolerance and Ambrose defeats him.
- 394 CE Theodosius bans public pagan rites; the Vestal fire is extinguished.
