No city in the ancient world was more thoroughly mythologized than Rome. Other cities had foundation stories and patron deities. Rome had an entire theological system built around the proposition that the city itself was sacred — chosen by the gods, protected by divine power, and destined for permanent greatness. The Latin phrase Roma Aeterna, the Eternal City, was not a boast. It was a religious claim, and the Romans defended it with the full apparatus of state religion.
To understand Roman mythology is to understand Rome as a sacred place. The gods did not simply exist in Rome — they were implicated in its founding, embedded in its geography, resident in its temples, and responsible for its survival. The city and its religion were inseparable in a way that had no parallel in the ancient world.
The Foundation
Rome’s mythological origin was double — and the doubling was deliberate. The city had two foundation stories that operated simultaneously and served different purposes.
The first story was the myth of Aeneas, the Trojan prince who fled the burning city of Troy carrying his father Anchises on his back and the household gods of Troy in his arms. Aeneas traveled west to Italy under the direction of the gods, specifically Jupiter, who had decreed that the Trojan bloodline would eventually produce a people greater than Troy itself. After years of wandering and warfare, Aeneas settled in Latium, married the daughter of the local king, and established the line that would eventually produce Romulus. This story, told most fully in Virgil’s Aeneid, connected Rome to the great mythological tradition of the Greek world and gave Rome a divine pedigree extending back to Venus herself — Aeneas was her son, which made the Julian dynasty, which claimed descent from Aeneas, literally divine.
The second story was the myth of Romulus and Remus, the twin sons of Mars and the Vestal Rhea Silvia, abandoned at birth, suckled by a she-wolf on the slopes of the Palatine Hill, raised by a shepherd, and eventually restored to power before Romulus killed his brother and founded the city on April 21, 753 BCE. This story was more specifically Roman — it had no Greek equivalent, it explained the city’s name, and it grounded Rome’s origin in the specific landscape of the Tiber valley rather than in the broad mythological geography of the Mediterranean. The she-wolf became Rome’s most enduring symbol. The date of April 21st became the dies natalis Urbis, the birthday of the city, celebrated annually.
The two stories were not in competition. Roman writers held them simultaneously, treating Aeneas’s arrival in Italy and Romulus’s founding of the city as two stages of a single divine plan, separated by several generations but unified by Jupiter’s will.
Sacred Geography
Rome’s physical landscape was not neutral terrain. Every significant feature of the city had mythological and religious meaning, and the Romans read their city the way other cultures read sacred texts.
The Capitoline Hill was the religious center of Rome and the seat of the Capitoline Triad — Jupiter, Juno, and Minerva — whose great temple dominated the hill’s southern summit. The Capitoline was where triumphs ended, where the victorious general ascended to offer his laurel wreath to Jupiter, where the Senate met in times of crisis, and where Rome’s sacred geese had once saved the city by cackling at a night attack by the Gauls in 390 BCE. The geese were maintained at state expense ever after, their descendants living on the Capitoline in perpetual gratitude.
The Palatine Hill, directly across the Forum from the Capitoline, was where Romulus had founded the city. The hut of Romulus — a thatched structure maintained and repaired by the Roman state throughout the Republic and Empire as an act of religious piety — stood on the Palatine into the imperial period. When it burned, it was rebuilt to exactly the same specifications. The hill became the preferred residence of the emperors, which is why the word palace derives from Palatium.
The Forum Romanum, the valley between the Capitoline and Palatine, was the civic and religious heart of the city. The Temple of Vesta and the House of the Vestal Virgins stood at its eastern end, the eternal flame burning continuously. The Regia, residence of the Pontifex Maximus and repository of sacred objects, stood nearby. The Temple of Saturn contained the state treasury. The Rostra, the speaker’s platform, was decorated with the bronze rams — rostra — taken from enemy ships, a physical reminder that Rome’s public life took place in a landscape defined by military victory and divine favor.
The Tiber River bounded and defined the city. The Romans called it Pater Tiberinus, Father Tiber, and worshipped it as a divine presence. It was the river into which Romulus and Remus had been cast and from whose bank the she-wolf had retrieved them. The island in the Tiber — the Isola Tiberina — was sacred to Aesculapius, the god of healing, and housed a famous healing temple. The river’s crossing points were sacred, and the bridges that spanned it were under the care of the Pontifex Maximus — pontifex means bridge-builder, and the title’s original meaning was almost certainly religious rather than administrative.
The Gods Who Protected Rome
Rome’s relationship with its gods was not simply one of worship. It was a formal alliance — a pax deorum, a peace with the gods — maintained through correct ritual observance and expected to deliver divine protection in return. The gods who protected Rome most directly were integrated into the physical and institutional fabric of the city.
Jupiter Optimus Maximus — Jupiter the Best and Greatest — was Rome’s supreme protector, resident on the Capitoline and the recipient of the great triumphal offerings that concluded Rome’s military victories. His cult on the Capitoline was the center of Roman state religion. Oaths were sworn by Jupiter. Treaties were made in his name. The consuls offered to him at the beginning of each year.
Juno was Rome’s protector in a more specific sense — she was the goddess whose geese had saved the Capitoline, and her aspect as Juno Moneta (the Warner) gave her temple on the Capitoline an additional significance: the Roman mint was located in her precinct, which is why moneta eventually became the word for money.
Mars was Rome’s founding deity in a different sense — not the protector of the city but the father of its founder. The Campus Martius, the Field of Mars, was the open ground outside the city walls where the Roman army trained and mustered. It was sacred to him, and his temples and altars stood there rather than within the city proper, because the army was required to lay down its weapons before entering Rome.
Vesta was perhaps the most intimately connected deity to Rome’s survival. Her eternal flame in the Forum — tended continuously by the Vestal Virgins, never allowed to go out — was not merely a ritual symbol. The Romans believed that if the flame died, Rome would die with it. On the rare occasions when the flame was accidentally extinguished, it was treated as a national emergency. The Vestals were among the most powerful religious figures in Rome, their persons sacrosanct, their intercession capable of saving condemned men, their presence required at all major state ceremonies.
The Name of Rome
The Romans had a secret. Rome’s true name — its divine name, the name that connected the city to the gods who protected it — was kept hidden. Ancient sources report that revealing it was a capital offense. The orator and scholar Varro wrote that the sacred name existed but refused to record it, on the grounds that doing so could expose Rome to enemies who might use the name in hostile ritual.
The goddess Angerona, whose festival was celebrated on December 21st, was associated with this secret. Her statue showed her with a finger pressed to bound lips — the gesture of enforced silence. Some ancient writers connected her specifically to the hidden name of Rome, the nomen arcanum that was never to be spoken.
Whether the hidden name was a genuine ancient tradition or a later mythological elaboration is impossible to determine from the surviving evidence. But the tradition itself reveals something important: the Romans understood their city’s relationship with the divine as something that could be disrupted, that required protection, that was not automatically guaranteed. Rome was sacred, but sacredness was fragile.
Roma Aeterna
The concept of Rome as eternal — Roma Aeterna — developed gradually but became one of the central claims of Roman religious and political thought. Jupiter, in the Aeneid, tells Venus that he has granted Rome imperium sine fine, empire without end. This was not merely poetry. Augustus, who commissioned the Aeneid, was articulating a theology of Roman permanence that would shape Roman self-understanding for centuries.
The Eternal City was not eternal because it was well-built or well-governed, though Romans believed it was both. It was eternal because the gods had decreed it. Jupiter had promised. The pax deorum would hold as long as Rome maintained the correct religious observances. This made Roman religion a matter of civic survival — not personal piety but collective insurance against divine withdrawal.
When Rome was sacked by the Visigoths in 410 CE, the theological shock was enormous. Augustine of Hippo wrote The City of God partly in response — a systematic argument that the Eternal City was not Rome but the heavenly Jerusalem, and that the fall of Rome did not represent a failure of divine protection but a necessary correction of Roman hubris. The argument required a book of twenty-two volumes because the claim it was rebutting — that Rome was under permanent divine protection — was deeply embedded in both Roman religion and Roman identity.
Rome in the Roman World
What distinguished Rome from every other ancient city was the completeness with which mythology and geography, religion and politics, divine plan and human history had been woven together into a single fabric. The city was not a backdrop for Roman mythology. It was its subject.
The gods were not simply worshipped in Rome. They were present in it — on the Capitoline, in the Forum, in the sacred groves, in the eternal flame, in the she-wolf’s descendants. Rome was a religious object as much as a political one, and the Romans’ extraordinary capacity for religious organization, ritual precision, and institutional continuity was in large part a response to that belief. If the gods had chosen this city, the very least its citizens could do was maintain it properly.
