It hangs from a chain in a museum case in Hannover, small and bronze and entirely matter-of-fact about what it is. A winged phallus with bird legs, the feet fitted with tiny rings that once held bells. The wings spread to either side. The whole object was designed to move — to hang in a doorway or above a cradle, to swing in a draft, to catch the light and ring softly when the air shifted. This is a fascinum, the primary Roman protective object against the evil eye, and it was as ordinary a household item in imperial Rome as a smoke detector is today: unremarkable in its presence, urgently necessary in its function, noticed only when it was absent.

At Millesgården, the sculptor Carl Milles’s studio and museum on the island of Lidingö outside Stockholm, a copy of the Capitoline Wolf stands in the open air, green with patina, the two infants nursing beneath the she-wolf’s belly on a red granite plinth. Ivy climbs the wall behind it. A stone face — a garden ornament — watches from the wall above. The composition is so familiar as to have become almost invisible through repetition: the wolf alert, ears pricked, facing left with a wariness that has not relaxed in two thousand years of bronze casting; the twins below, pudgy and insistent, entirely unconcerned with the predator feeding them. The image is Rome’s founding symbol, its most exported icon, the picture that appeared on Roman coins in the second century BC and on Italian government documents in the twenty-first century AD. It has been in continuous circulation as a symbol of Roman identity for over two millennia, which is not an achievement many images can claim.

The bronze is perhaps eight centimeters tall and has been in Hannover’s Museum August Kestner for longer than most living people can account for. It shows a Thracian gladiator — the Thraex type, one of the most popular and most recognizable in the Roman arena — in full equipment: the curved sica sword, the small rectangular shield, the elaborate crested helmet with its full-face visor, the greaves protecting both legs. The label reads simply Gladiator, sog. Thraex, Roman Imperial period, first century AD. It sits on a glass shelf among other Roman bronzes, modest in scale, extraordinary in specificity. Whoever made this knew exactly what a Thraex carried and wore. They made this figure because there was a market for it. That market is itself part of the story.

A museum case in Berlin’s Altes Museum holds a collection of Roman domestic bronzes from Rome and Pompeii, first through fourth century AD, under a label that states its subject with admirable directness: Luxury in the Roman house. The contents repay attention. Two griffins — mythological hybrids of eagle and lion, rendered with precise musculature — served as the decorative supports of a folding table, their bodies forming the legs, their wings providing the lateral bracing. A satyr and nymph group, extravagantly detailed, formed the foot of a large bronze vessel. Small bronze ducks and swans — the fulcra — decorated the scroll-ends of couches and dining beds, the curved terminals that distinguished a proper Roman reclining couch from mere functional furniture. Two portrait busts on red marble pedestals completed the ensemble. None of this was structural. All of it was mandatory, in the sense that a wealthy Roman household without this level of decorative investment was announcing, inadvertently, that its owner could not afford it.

The bronze is Roman, from the Albani Collection, and it sits now in the Louvre’s antiquities hall on a plinth of dark marble, moving through nothing. The lion has one paw resting on a sphere — the globe, the world, the totality of things worth possessing — and the posture is neither aggressive nor relaxed. It is the posture of ownership. The sphere is already subdued. The question of whether anything else needs subduing remains open. This is not a lion that has just won. This is a lion that expects to win.

Edward Poynter’s Cave of the Storm Nymphs, his Israel in Egypt, and his Lesbia, along with the Roman paintings of his contemporaries John William Waterhouse and Edward John Poynter, belong to a specific Victorian sub-genre that might be called moral archaeology: the use of meticulously researched ancient settings to explore contemporary anxieties about gender, sexuality, empire, and the relationship between civilization and decadence. These paintings are not straightforwardly about Rome or Egypt or Greece. They are about Victorian England, using the distance of antiquity as a frame that permitted the examination of subjects that contemporaneity made difficult.

Frederic Leighton, Lord Leighton, President of the Royal Academy from 1878 until his death in 1896, was the dominant figure in British academic painting in the second half of the nineteenth century, and his engagement with classical antiquity — primarily Greek and Roman — was the defining subject of his career. Unlike Alma-Tadema, whose classical paintings were organized around the reconstruction of material culture, or Poynter, whose Romans served moral arguments, Leighton’s classicism was organized around a single overriding concern: beauty as an end in itself, the human figure in relation to drapery and landscape, the moment of formal perfection that painting could capture and sustain.

Roman naming conventions are among the more counterintuitive aspects of the culture for modern readers, and the confusion they generate is not merely academic. Understanding Roman names is understanding something important about Roman identity, social structure, and the relationship between the individual and the family — a relationship that was organized very differently from the modern Western model.

The classical Roman name for a male citizen of the Republic consisted of three parts: the praenomen, the nomen, and the cognomen. The praenomen was the personal name — the equivalent of a first name — but it was used almost exclusively within the family. Romans did not address each other by praenomen in public contexts. There were very few praenomina in use — approximately eighteen were common, and many families used only two or three across generations — which meant that they were not functionally distinctive at any scale beyond the household. The praenomen was abbreviated in writing: Gaius became C., Marcus became M., Lucius became L. (confusingly, since Gaius was abbreviated C rather than G, a legacy of archaic Latin spelling).

Latin is not a dead language. The claim that it died with Rome is one of the more misleading things said about either Latin or Rome, and correcting it requires understanding what actually happened to the language after the Western Empire’s political structures dissolved in the fifth century. Latin did not die. It evolved, as all living languages do, into forms that its classical speakers would have had difficulty understanding. The languages that evolved from it — Italian, French, Spanish, Portuguese, Romanian, Catalan, Galician, Occitan, and several others — are Latin, in the same sense that modern English is Old English: substantially transformed, but continuous. They did not replace Latin; they are Latin, moving through time.

Mithras had no mythology that anyone has found. The god who attracted devotees across the Roman Empire for three centuries, whose cult spread particularly among soldiers and merchants, whose underground temples — mithraea — have been excavated from Britain to the Euphrates, left no sacred texts, no founding narrative, no theology explained in its own terms. What we know about the Mithraic mysteries we know from the material record, from hostile Christian commentary, and from scholarly inference — a body of evidence that has produced sustained academic disagreement and no consensus on the most basic questions. Where did the cult come from? What did the central image mean? What happened in the ceremonies? The answers remain genuinely uncertain.

In 8 AD, Augustus exiled Ovid to Tomis on the Black Sea — modern Constanța in Romania, the edge of the civilized world as Rome understood it — for reasons he described cryptically as a poem and a mistake. The poem was the Ars Amatoria, a didactic work on the art of seduction published nearly a decade earlier, which Augustus had apparently decided was a contribution to the moral looseness he had spent his reign trying to suppress. The mistake is unknown and has generated scholarly speculation for two thousand years. Ovid spent the remaining ten years of his life on the Black Sea shore writing poems of exile — the Tristia and the Epistulae ex Ponto — that constitute the most sustained literary response to political persecution in antiquity, and he died without recovering the imperial favor he spent those years petitioning for.

The augurs were among the most important religious officials in Rome, and their function was specific: they observed and interpreted signs — auspices — that indicated whether the gods approved of a proposed action. Before a general led his army into battle, before a magistrate held a public assembly, before a colony was founded or a treaty ratified, the auspices were taken. A favorable sign meant the action could proceed. An unfavorable sign meant it could not — at least not on that day, in that form. The political implications of this system were considerable, and the Romans who operated it were not naive about the opportunities it created.

Romans played games everywhere. Game boards scratched into the steps of the Colosseum, carved into the pavements of the Roman Forum, incised into the floors of military barracks from Hadrian’s Wall to the Syrian desert — the physical evidence for Roman gaming culture is distributed across every context where Romans spent time waiting, resting, or socializing. The games themselves ranged from dice games requiring no equipment beyond three cubes of bone or ivory to board games of genuine strategic complexity, and they were played by everyone: soldiers, merchants, slaves, emperors. Claudius was reportedly so devoted to dice games that he designed a special board for playing in his carriage. Augustus played board games regularly. The imperial dignity was not considered incompatible with sitting across a game board from someone.

The Romans buried their dead outside the city. This was law and custom simultaneously — the Twelve Tables prohibited burial within the city limits, and the prohibition was observed with sufficient consistency that the great roads leading out of Rome were lined with tombs for kilometers. The Via Appia’s funerary landscape, stretching from the Porta Capena south through the Alban hills, was among the most concentrated assemblages of monuments to the dead in the ancient world, ranging from the elaborate mausolea of senatorial families to the simple markers of freed slaves and soldiers. Death organized itself along the roads the living traveled, which meant that Romans moved through the presence of their dead every time they left the city.

Roman education was not a system. There was no state curriculum, no network of public schools funded by the central government, no standard examination or qualification. What existed instead was a market: families who could pay hired teachers, sent children to private schools, or employed educated slaves as tutors, while families who could not afford these options relied on whatever the local community provided, which was often very little. The result was predictably unequal and surprisingly effective at its stated purpose — producing an elite capable of governing an empire — while being largely irrelevant to the majority of the population who needed agricultural or craft skills that formal education did not provide.

Roman medicine was Greek medicine operating in Latin. The systematic approach to understanding the body that the Romans inherited and developed had been established by Greek physicians — Hippocrates in the fifth century BC, whose school produced the first sustained attempt to explain disease through natural causes rather than divine intervention; Herophilus and Erasistratus in the third century BC, who performed human dissection at Alexandria and advanced anatomical knowledge beyond anything previously achieved. By the time Rome had absorbed the Greek world, Greek physicians were practicing in Roman cities, Greek medical texts were being translated and adapted, and the leading medical authority of the imperial period — Galen of Pergamon — wrote in Greek while practicing in Rome as physician to the emperors Marcus Aurelius, Commodus, and Septimius Severus.

The Roman tavern — the caupona or taberna — was the social space of the working poor and the urban transient, serving wine, hot food, and a place to sit to the vast majority of Rome’s population who had neither the household space for entertaining nor the social standing for the formal dinner party. It was also, in the view of the Roman elite who wrote most of the surviving literature, a place of moral danger: noisy, crowded, frequented by the wrong people, associated with cheap wine, dice games, prostitution, and the general dissolution of Roman values that the upper classes perpetually feared was eroding the foundations of society. The complaints were consistent across centuries and the taverns thrived regardless, which is usually a reliable indicator of genuine social function.

The Roman theater had Greek ancestors and Roman ambitions, which meant it was grander, more permanent, and more politically charged than the tradition it inherited. Greek theaters were cut into hillsides; Roman theaters were freestanding structures built anywhere the politics and patronage required, carrying their own support in the massive substructures that allowed them to be erected on flat ground without natural topography to exploit. The technical capacity to build a freestanding theater — requiring vaulted concrete substructure at a scale that Hellenistic builders had not attempted — was itself a statement about Roman engineering ambition, and the theaters that survive from across the empire, from Orange in France to Aspendos in Turkey, demonstrate that the ambition was fulfilled consistently.

The unconquered sun — Sol Invictus — was the dominant religious force in the Roman Empire during the decades immediately before Christianity became the state religion, and the competition between them was closer than the outcome suggests. Aurelian, who reunified the empire after the chaos of the third century and who is one of the more underrated figures in Roman imperial history, established Sol Invictus as the supreme deity of the Roman state in 274 AD, built a spectacular temple in Rome, and created a new priesthood — the pontifices Solis — to administer its cult. For roughly forty years, the sun god was in a position of official supremacy that Christianity would not achieve until the reign of Theodosius nearly a century later.

In 186 BC, the Roman Senate issued the senatus consultum de Bacchanalibus — the decree concerning the Bacchic rites — one of the most extensive surviving Roman legal documents and the record of what the Roman state did when it decided that a religious movement had gotten out of hand. The decree restricted the Bacchic associations throughout Italy, required their leaders to present themselves for investigation, set numerical limits on how many people could participate in the rites, and prohibited Bacchic priests from holding funds or conducting initiations without specific Senate authorization. Thousands of people were prosecuted; the sources describe executions in numbers that suggest a systematic repression rather than individual criminal cases. The Bacchanalia, as the Roman sources describe it, was the first large-scale persecution of a religious movement in Roman history.

Isis arrived in Rome over official objections. The Roman Senate banned her worship multiple times in the first century BC — in 58, 53, 50, and 48 BC, with varying degrees of enforcement — ordering her altars demolished and her images removed from the city. The bans failed because the cult’s appeal was stronger than the official resistance, and by the first century AD the goddess who had been repeatedly expelled was being worshipped in temples funded by emperors. Caligula built her a major temple in the Campus Martius. Vespasian and Titus celebrated their triumph over Judaea in her temple precinct. Commodus appeared in her processions in priestly dress. Whatever the Senate of the Republic had thought about Egyptian divinities, the Empire had reached different conclusions.

Rome was not original in its theology, and it did not pretend to be. The Romans were systematic borrowers of divine power, operating on the practical assumption that a god who worked was worth incorporating regardless of origin. The result was a pantheon that was Greek at its core, overlaid with indigenous Italian tradition, supplemented by imports from Egypt, Persia, and Syria, and eventually contested and replaced by a monotheism that originated in Judea. Roman religion was an accumulation, not a creation.

The Roman bath was not primarily about hygiene. That framing, which modern people find intuitive, misses what made the baths central to Roman urban life for centuries. The bath was a social institution — a place where Romans of different classes shared the same water, the same space, and the same several hours of the afternoon in an arrangement that had no precise equivalent before or since. It was the forum, the gym, the library, the barbershop, and the social club compressed into a single building and made available, often for free or for a nominal fee, to virtually everyone in the city.

The calendar you use today is a Roman calendar. The twelve months, the seven-day week borrowed from Near Eastern sources and transmitted through Rome, the numbering of the years from a fixed point that eventually became the Christian era — all of these are features of the system that Julius Caesar reformed in 46 BC and that the Catholic Church adjusted in 1582 with modifications so minor that most countries now use what is, in its essentials, the calendar Caesar commissioned. You wake up on a Tuesday in October because a Roman dictator in the first century BC decided to align the civil year with the solar year, and his solution was good enough to last two thousand years.

The Saturnalia began on December 17 and lasted, in its imperial development, for seven days. It was the most popular festival in the Roman calendar, the one that Roman writers mention most frequently as a cherished institution, and the one whose customs have attracted the most scholarly attention for their relationship to the Christmas traditions that eventually overlapped with and largely replaced them. For the duration of the Saturnalia, Roman social life was deliberately inverted: slaves were served dinner by their masters, social distinctions were relaxed, gambling was legally permitted, gift-giving was universal, and the general atmosphere of licensed excess provided a temporary release from the hierarchical rigidity that organized Roman life during the other fifty weeks of the year.

The Roman triumph — the procession through the city in which a victorious general displayed his captives and the spoils of conquest before depositing the latter in the treasury and offering thanks at the temple of Jupiter Capitolinus — was the most spectacular public ritual of the Roman world, and its visual representation has served as propaganda for European rulers from the Renaissance through the nineteenth century. The triumph’s logic — the hero returns, the enemy is displayed, the city is made to feel the extent of its power — was available for appropriation by any ruler who needed to communicate the same things, and the painters who rendered ancient triumphs for modern patrons understood they were serving both historical documentation and political argument simultaneously.

The Vestal Virgins were the most socially privileged women in Rome and, simultaneously, subject to a punishment for a specific transgression — unchastity — that no other Roman citizen faced: burial alive. The combination of exceptional status and exceptional vulnerability was not a paradox in the Roman religious framework but a logical consequence of what the Vestals were understood to represent. Their virginity was not a personal moral choice; it was a civic necessity. The sacred fire they tended in the Temple of Vesta was, in Roman religious understanding, the eternal flame of Rome itself, and its maintenance by women who were themselves unbreached vessels was what kept Rome’s divine favor intact. When a Vestal was unchaste, it was not a private transgression but a public catastrophe that had to be addressed with proportionate ritual severity.

Roman food is one of the most misrepresented topics in popular history. The standard image — wealthy Romans reclining at banquets, eating dormice and vomiting between courses to make room for more — is accurate for a narrow slice of Roman society at a specific moment in imperial history and almost entirely wrong for everyone else. Most Romans ate simply, cheaply, and without couches.

The staple of the Roman diet was grain. Bread and porridge — puls, a thick wheat or spelt mash — were the foundation of what the majority of the population ate every day. Grain was so central to Roman social stability that the state organized its supply directly: the annona, the grain dole, eventually provided free or subsidized grain to several hundred thousand residents of the city of Rome. This was not charity in the modern sense. It was political infrastructure. A city that could not feed its population was a city that would riot, and Rome had learned this lesson repeatedly.

Roman clothing was a system of social communication before it was a system of warmth or modesty. What a Roman wore told every observer who saw them something specific about their legal status, their social rank, their occupation, their marital status, and the occasion they were attending. The reading of clothing was automatic and precise in a society that had neither name tags nor business cards and that organized its social interactions around the rapid assessment of social position. Dress was not merely decorative; it was informational, and the information it carried was regulated by law and custom with a specificity that modern dress codes do not approach.
