Rome copied Carthage plank by plank, then erased it (146 BCE)

Before: a republic that could not sail

When Rome and Carthage went to war in 264 BCE, the two powers were not two versions of the same thing. Carthage was a Phoenician maritime civilisation more than five centuries old, whose wealth came from ships, harbours, and a trading network that ran from the Levant to the Atlantic coast of Iberia. Rome was a land power that had never fought a war at sea. Its strength was a citizen infantry drawn from the farms of central Italy, and its horizon, until that decade, ended at the Italian coastline. The collision that followed would make Rome the master of the western Mediterranean — but it did so by forcing Rome to become, in three specific respects, a copy of the enemy it was destroying.

To feel what changed, you have to see the Republic as it was before it borrowed. The Rome of the early third century BCE had no war fleet worth the name, no overseas province, no systematic science of agriculture written in Latin, and no plantation economy running on chattel slaves at industrial scale. Each of those things would arrive, and each would arrive through Carthage.

The city that Rome would erase

It is worth being concrete about what Carthage was, because the record ends with its destruction, and the scale of the loss is part of the cost. Founded as a colony of Tyre around 814 BCE, Carthage had outlived its Phoenician mother-cities to become the dominant commercial power of the western Mediterranean. Its double harbour — a rectangular commercial basin opening into a circular military port, the cothon, ringed with ship-sheds for hundreds of warships — was an engineering marvel that Greek and Roman visitors described with awe. Behind the walls rose the citadel of Byrsa; around the city spread some of the most productive farmland in the ancient world, the Cap Bon peninsula and the Bagradas valley, worked on a scale Rome had never seen ⁸.

Carthaginian power rested on things Rome lacked. It rested on seamanship: the Carthaginians built and crewed the largest war fleets of the age, and their explorers, if the tradition of Hanno's voyage is trusted, had coasted West Africa. It rested on commerce: a web of treaties, ports, and staple-trades in silver, tin, and agricultural produce. And it rested on a scientific agriculture that had no Latin equivalent. When Rome finally looked closely at Carthage, it did not find a barbarian rival. It found a civilisation that already possessed the three capacities Rome most needed — and would take.

The two states even made war differently, and the difference matters for what follows. Carthage was a mercantile oligarchy that fought largely with hired armies — Libyan infantry, Numidian horsemen, Iberian and Gallic and Balearic mercenaries — commanded by its own aristocrats but manned by paid outsiders, while its citizens crewed the fleet and ran the trade. Rome fought with its own citizens, drafted by the census, an army that was also the people. This is why the naval channel of the transmission cut so deep: Carthage's advantage lay precisely in the maritime domain where Rome had no tradition at all, and closing that gap meant not refining an existing Roman skill but manufacturing one from nothing, on a captured template, in a matter of weeks ¹¹.

A land power on a borrowed sea

The relationship began not as rivalry but as subordination. The earliest treaty between the two states, which the Greek historian Polybius copied from the bronze tablets preserved in the Roman treasury, dates to 509 BCE — the first year of the Republic ¹. Its terms are those of a junior partner accepting a senior power's rules. Roman ships were forbidden to sail beyond the "Fair Promontory" north of Carthage; the Carthaginians reserved Libya and Sardinia to themselves and admitted Romans to their Sicilian markets only under supervision. A second treaty, around 348 BCE, tightened the restrictions further, and a third followed ¹⁷.

For two centuries Rome accepted this maritime order because it had no means to challenge it. When the Republic needed ships, it requisitioned them from the Greek coastal cities of southern Italy — the socii navales, the "naval allies" — because it had no navy of its own. Roman power was legionary and terrestrial: the maniple, the citizen levy, the road and the marching camp. The idea that Rome might contest control of the sea itself was, before 260 BCE, simply outside the categories available to the Roman state. Polybius, looking back, is explicit that the Romans came to naval war as absolute beginners, "not having even a notion" of how a quinquereme was built ¹.

The citizen's farm

Roman agriculture, in the same period, was organised around a moral and military ideal: the citizen-soldier who worked his own small plot and left the plough to serve in the legions. The story of Cincinnatus — summoned from his tiny farm to save the Republic, then returning to it once the crisis had passed — was the fable the Romans told about themselves. Landholding and citizenship were bound together: the census that ranked a man's property also fixed his place in the legion, and the small proprietors, the assidui, were the backbone of the army. To be landless was to be proletarius, counted only for the children one produced.

What Rome did not have was a body of agricultural knowledge organised as a science. Marcus Porcius Cato's De Agri Cultura, written around 160 BCE, is the earliest surviving work of Latin prose on farming, and it is a rough, practical handbook — a jumble of recipes, rituals, contracts, and rules of thumb, not a system. There was no Latin agronomy comparable to the theorised literature that already existed in the Greek world and, as Rome would discover, in Carthage. Slavery existed in Roman Italy, but the great slave-worked estate — the plantation run for market profit by a resident overseer and a gang of purchased human beings — was not yet the dominant form of rural production. The land was still, in ideal and largely in fact, a landscape of citizen smallholders.

No word for a province

Before 241 BCE, Rome had no overseas territory at all, and therefore no machinery for governing or taxing land across the sea. The Latin word provincia did not originally mean a place. It meant a task — the sphere of responsibility assigned to a magistrate holding imperium. Rome had conquered much of Italy, but it had absorbed those conquests through a patchwork of alliances, colonies, and grants of citizenship, binding defeated peoples into the Roman military system rather than draining them through a bureaucracy.

The apparatus that would later define Roman imperialism — a fixed provincial territory, a resident governor, an annual tax assessed and collected by contract, a flow of grain and silver back to the capital — did not exist because the problem it solved did not yet exist. Rome had never held a rich, populous, agriculturally productive land at a distance and had to decide how to extract from it. The first time it faced that problem was in Sicily, in 241 BCE, and the answer it reached for was not one it invented. It was an answer that Carthage and the Greek tyrants of Sicily had already written, and that Rome simply kept.

The transmission: copying the enemy

The transmission from Carthage to Rome is not a story of gentle diffusion across a contact zone. It runs through three channels — naval technology, provincial administration, and agricultural science — and in each channel Rome took what it needed by force, by reverse-engineering, or by the deliberate salvage of a defeated culture's knowledge. The mechanism is conquest, and the record's spine is the irony that follows: Carthage's most durable gifts to the world were extracted from it by the power that annihilated it.

The ship on the beach

The clearest single episode is naval. In the opening years of the First Punic War, Rome realised it could not defeat a sea power with an army alone, and resolved to do something it had never done: build a battle fleet from nothing. Polybius records what happened next, and the story is almost too neat to be true — except that Polybius, writing a century later with access to Roman records and Carthaginian survivors, evidently believed it, and no better account survives.

Early in the war a Carthaginian warship, a quinquereme, ran aground and fell into Roman hands. The Romans had no experience building such vessels; the quinquereme was a Carthaginian and Hellenistic design, not an Italian one. So, in Polybius's account, they used the captured ship as their template and copied it, timber by timber. "Had this not occurred," he writes, "they would have been entirely prevented from carrying out their design by lack of practical knowledge" ¹. From that single grounded hull the Republic laid down a fleet of a hundred quinqueremes and twenty triremes — and Polybius insists the whole programme, from the felling of the standing timber to the launch, took only about sixty days.

They still had no rowers who had ever pulled an oar in formation. Polybius describes the improvised solution with an engineer's admiration:

While the ships were on the stocks, the Romans seated their future oarsmen on rowing-benches set up on dry land, arranged exactly as they would sit aboard, and drilled them in the stroke — teaching men the rhythm of the oar before they had ever touched water ¹. It was a crash course in a maritime skill that Carthage had accumulated over centuries, compressed into weeks. The improvisation was audacious and, in the long run, costly: Roman crews remained poor seamen for a generation, and the Republic lost enormous fleets — perhaps a hundred thousand men in the storms of 255 and 253 BCE — to weather its inexperienced captains could not read. Rome learned the sea, but it paid tuition in drowned men ¹⁴.

The raven

Even copied ships could not make Roman crews the equals of Carthaginian seamanship, so Rome changed the terms of the contest. Roman engineers fitted their new vessels with the corvus — the "raven" — a hinged boarding-bridge roughly eleven metres long with a heavy iron spike beneath its far end. When a Carthaginian ship closed in, the bridge dropped, the spike bit into the enemy deck, and Roman legionaries stormed across. The device converted a naval battle into an infantry engagement, which was the one kind of fighting Rome already knew how to win.

The corvus made its debut at Mylae in 260 BCE, off the north coast of Sicily, where the consul Gaius Duilius destroyed or captured some fifty Carthaginian ships in Rome's first naval victory. Rome commemorated it by erecting a columna rostrata — a column decorated with the bronze rams of the captured ships — in the Forum, and Duilius was granted a lifelong honour of being escorted home by torchlight and flute. Within a few years a power that had never fought at sea was winning fleet actions against the greatest naval civilisation of the western Mediterranean, using its enemy's own hull design turned to its own tactical strengths. The transmission was not abstract. It was a Carthaginian ship, copied, with a Roman idea bolted to the bow ¹⁴.

The scale of what Rome had built escalated quickly. At Cape Ecnomus in 256 BCE, off southern Sicily, Roman and Carthaginian fleets met in what may have been the largest naval battle in history by the number of men engaged — perhaps three hundred thousand rowers and marines across some seven hundred ships — and Rome won it, then carried the war into Africa itself. The invasion under the consul Marcus Atilius Regulus reached the walls of Carthage before it was shattered; Regulus was captured, and the African expedition ended in disaster. Rome had learned to reach across the sea and strike at the enemy's home, and it had learned that lesson, in barely a decade, from ships copied off a beach. The apprenticeship was brutal and expensive, but it was decisive ¹³.

Sicily, and the machine of a province

The First Punic War ended in 241 BCE with Carthage's cession of Sicily. Rome now held, for the first time, a rich overseas land — and had to decide how to govern it. The instrument it adopted, the Lex Hieronica, was not a Roman invention. It was the taxation system of Hieron II of Syracuse, itself overlapping with the older Carthaginian practice of taxing western Sicily, taken over more or less intact ⁷. Its central provision was the decuma: a tithe of one-tenth of the grain harvest, assessed each year against declared acreage and collected through licensed contractors under sealed, published rules.

Rome kept the system because it worked. A century and a half later, prosecuting the rapacious governor Gaius Verres, Cicero treats the Lex Hieronica as the settled and admired framework of Sicilian taxation — a carefully drawn law, efficient and, in principle, fair to the cultivator, whose abuse by Verres was precisely what made his conduct criminal ⁶. Sicily became the granary that fed the city of Rome, and the fiscal architecture first assembled there — a fixed provincial territory, an annual tithe on production, and collection farmed out to private syndicates of publicani — became the template for provincial administration across the empire that followed. Rome's first province was, in its very machinery, an inheritance from the peoples it had conquered.

The one book they kept

The third channel is the strangest, because it happened after Carthage was already dead. When Roman troops took the city in 146 BCE and the Senate ordered it razed, the libraries of Carthage — the accumulated written memory of a civilisation more than six centuries old — were handed over to the allied Numidian kings of Africa and effectively lost. With one exception. Pliny the Elder records the decision with unusual precision:

The Senate, having given Carthage's libraries away to the princes of Africa, resolved that one work alone should be translated into Latin: the twenty-eight books on agriculture written in Punic by a Carthaginian named Mago ². The task was entrusted to men who knew the Carthaginian language, and the senator Decimus Junius Silanus was commissioned to produce the Latin version at public expense. A parallel Greek adaptation was made by Cassius Dionysius of Utica — twenty books — and later condensed by Diophanes of Nicaea into six. Of an entire literature, Rome chose to preserve exactly one book, a farming manual, because it was useful.

The choice is so pointed that it has been read as an act of translation-as-conquest: the victor absorbs the defeated culture's most practical knowledge into its own language while consigning the rest to oblivion. Mago's books covered the whole of estate agriculture — the siting and planting of vineyards and orchards, the selection and care of oxen and horses, the management of bees, the making of wine and raisins, the duties of the overseer, the running of the great farm as a productive enterprise. It was, in Jacques Heurgon's phrase, une véritable Bible agronomique — a veritable agronomic bible — for an Italian rural economy then shifting from smallholding to latifundia, and Rome made it Latin ⁹.

Why a farming manual, of all the books Carthage held? Because it answered a Roman need. Rome in 146 BCE was awash in conquered land and captured people, and the great estate worked by slaves for market sale was becoming the central economic institution of Italy. A comprehensive, systematic guide to running exactly that kind of enterprise — written by the people who had perfected it on the fertile land around Carthage — was worth more to the Senate than all the histories and hymns of Punic civilisation combined. The decree to translate Mago is one of the clearest windows in the ancient record onto what a conquering power actually values in the culture it destroys: not its memory, not its gods, not its poetry, but its methods.

What changed and what was replaced

Each of the three transmissions reshaped Rome, and each displaced something that had been there before. The Republic that emerged from the Punic Wars was a naval and imperial power with a scientific agronomy and a plantation economy — and it had become that power by absorbing the operating system of the culture it destroyed, while the culture itself was deleted.

A republic learns to rule the sea

The most visible change was strategic. Before 260 BCE Rome was a land state that borrowed ships; after the Punic Wars it was the dominant naval power of the western Mediterranean, then of the whole basin. The fleet that began as a copy of a grounded Carthaginian hull became a permanent instrument of Roman power — the guarantor of the grain routes that fed the capital, the means by which armies reached Greece, Africa, and Iberia. In 67 BCE, Pompey would sweep the Cilician pirates from the sea in a single season, and the Mediterranean the Romans called Mare Nostrum, "Our Sea," became a Roman lake patrolled by fleets whose distant ancestor was a wreck on a Sicilian beach.

The strategic category that had not existed in the Roman mind before 264 BCE — sea power as an object of the state — was permanent thereafter. It is a striking measure of the transmission that Rome, having learned naval war from Carthage in order to destroy it, would go on to depend on the sea for its survival: on the African and Egyptian grain that sailed to Ostia, on the naval lanes that held the empire together. The apprentice outlived the master and inherited its element.

The province as a machine

The Sicilian settlement of 241 BCE created something even more consequential than a fleet: a reusable method for turning conquered land into revenue. The components, first bolted together in Sicily, hardened into the standard architecture of Roman rule:

• A defined provincial territory with fixed borders, distinct from the city-state alliances of Italy.
• A resident governor holding imperium, sent out annually from Rome to command and to judge.
• An annual tithe (decuma) assessed on agricultural production, plus requisitioned and purchased grain.
• Collection contracted out to private syndicates of publicani, who advanced the sum to the treasury and recouped it — with profit — from the provincials.
• A flow of grain, silver, and enslaved people back to Italy that increasingly financed the politics and armies of the late Republic.

This machine was exported wherever Rome conquered: to Sardinia and Corsica within a decade, to the two Spanish provinces, to Africa itself, to Macedonia and Asia, to Gaul. Its efficiency was also its cruelty. Tax-farming gave the publicani a direct incentive to extract more than the law allowed, and provincial governorships became notorious engines of private enrichment — the abuse Cicero prosecuted in the person of Verres was the system working as designed, not failing. The provincial model that made Rome rich began as a Sicilian-Carthaginian inheritance and became the fiscal skeleton of an empire that would outlast the Republic by five centuries.

The system also fed back into Roman politics with corrosive force. When the wealthy province of Asia was organised in 123 BCE, Gaius Gracchus placed its lucrative tax contracts in the hands of the publicani and the courts that judged provincial governors in the hands of their class — knitting the machinery of extraction into the factional war at the centre of the Republic. The revenues that the province-machine pumped back to Italy financed the armies, the grain doles, and the electoral bribery of the late Republic; provincial plunder became a currency of domestic power. What had begun in 241 BCE as a way to tax a single island had become, within a century, one of the engines driving Rome toward civil war. The inheritance from Carthage was not only a set of tools but a set of appetites.

Mago's ghost in the Latin field

Mago's translated manual did something subtler and longer-lasting. It became the root authority of the entire Roman agronomic tradition. Varro, writing his Res Rusticae in 37 BCE, sets Mago at the head of the fifty-odd foreign authorities he lists. Columella, in the most systematic Latin work on farming ever written, calls Mago "the father of husbandry" and quotes his advice directly — including the famous maxim that a man who buys an estate should sell his town house, so that he loves the country and not the city ³⁴. Pliny the Elder mines him repeatedly across the Natural History; the later writer Gargilius Martialis cites him still. Through these Latin authors, a Carthaginian's lost book shaped how the Roman world thought about land for the better part of five centuries ²⁹.

But Mago's manual was not neutral technical advice. It described, and Rome adopted, a particular model of agricultural production: the large estate worked by slave labour under professional management for market sale. This was the plantation logic, and in Roman Italy it found its fullest expression in the latifundium — the vast slave-run estate that spread across the peninsula and the provinces in the last two centuries BCE. The Carthaginian science of intensive, market-oriented, slave-powered agriculture did not merely inform Roman farming; it helped industrialise Roman chattel slavery, supplying the intellectual framework for turning captured human beings into an agricultural workforce on a scale the earlier Republic had never known ¹⁵.

The smallholder undone

Here the transmission turned against the Republic's own foundations. The citizen-soldier's farm — the smallholding that had been the moral and military basis of the Roman state — could not compete with the latifundium. As Roman conquests poured hundreds of thousands of captured slaves into Italy and the plantation model spread, small farmers were bought out, forced out, or ruined by the long overseas military service the wars demanded, and the land consolidated into great estates worked by the enslaved. The displaced flowed into Rome as a landless urban poor. The historian Appian, looking back, saw this consolidation of land into slave-worked estates as the root cause of the Republic's coming convulsions ⁵.

The human meaning of that displacement was not lost on contemporaries. Tiberius Gracchus, according to Plutarch, told the Roman crowd that the wild beasts of Italy had their dens and holes to lie down in, while the men who fought and died for Italy wandered homeless with their wives and children, owning nothing but the air and the light — masters of the world, the tribune said, who had not one clod of earth to call their own. The soldiers who had conquered the Mediterranean returned to find their farms swallowed by the slave-worked estates their own conquests had made possible. The plantation had eaten the smallholder who had built the army that made the plantation ¹⁶.

This was the crisis the brothers Tiberius and Gaius Gracchus tried and failed to solve with land reform in 133 and 121 BCE. Both were killed — Tiberius clubbed to death by senators, Gaius driven to suicide — and their deaths opened the century of civil war that ended the Republic. The plantation economy that helped destroy the smallholder-citizen was, in part, a Carthaginian import: the very system Mago had systematised, realised on Italian soil at the expense of the class that had made Rome. The mosaic of the great estate of a lord named Julius, laid in Roman Africa on the land Carthage once farmed, is the picture of what won — the seasons of labour, the produce carried to the master and mistress, the estate as an entire world.

What the cost was

The transmission from Carthage to Rome has, at its centre, a bill that can be stated with unusual precision, because the ancient sources counted. It was paid in 146 BCE, and it was paid by a city.

The figs on the Senate floor

The Third Punic War was not a response to a Carthaginian threat. Carthage, stripped of its empire and its fleet after the Second Punic War, had become a prosperous trading city and a military nonentity, bound by treaty and hemmed in by the Numidian king Masinissa. Its prosperity was itself the provocation. The censor Cato the Elder, who had served on an embassy to Carthage around 152 BCE and seen its recovered wealth at first hand, took to ending every speech in the Senate — on any subject — with the same demand: Carthago delenda est, "Carthage must be destroyed." He is said to have shaken fresh Carthaginian figs from the folds of his toga onto the Senate floor, telling the senators that the land which grew such fruit lay only three days' sail away. The war he agitated for was launched in 149 BCE on manufactured pretexts, and its declared object was annihilation ¹⁰¹².

Carthage, ordered by Rome to abandon its city and move inland, chose instead to fight. What followed was not a battle but a slow strangulation: a three-year siege in which the Carthaginians, having surrendered their weapons in a failed bid for peace, forged new ones from the metal of their own city and their women cut their hair for bowstrings. It is one of the ancient world's set-pieces of doomed resistance, and it makes the ending harder, not easier, to read ¹¹¹³.

Eight days in 146

The end came in the spring of 146 BCE under the command of Scipio Aemilianus. Roman troops breached the walls and fought their way inward through six days of street combat, house to house and roof to roof, up the narrow streets toward the citadel of Byrsa; the last defenders and refugees held out in the temple of Eshmun and burned with it rather than surrender. The specifics are the point:

• The city had held, before the war, on the order of several hundred thousand people; ancient figures of 700,000 are certainly inflated, but the population was vast.
• The dead across the final assault ran into the tens of thousands at least; Appian's figure of great slaughter is exaggerated in detail but describes a massacre.
• Roughly fifty thousand survivors — the sources give about 50,000 to 55,000, including some 25,000 women — were sold into slavery ⁵.
• The city was systematically demolished over many days, its harbour wrecked, its site formally cursed, and its territory annexed as the Roman province of Africa, administered from Utica. (The often-repeated detail that Rome sowed the ground with salt is a modern invention, absent from every ancient source — the erasure needed no such embellishment.)

The end had its named figures. The Carthaginian commander Hasdrubal, who had sworn to die in the ruins, came out and threw himself on Scipio's mercy; his wife, according to Appian, denounced him from the roof of the burning temple of Eshmun as a traitor and a coward, killed their two children before his eyes, and threw them and then herself into the flames rather than be led in a Roman triumph. Whatever the embellishments of the tradition, the scene fixes the register of the ending: a city that chose immolation over surrender, and a conqueror who wept as he won ⁵.

Polybius, who stood beside Scipio as the city burned, recorded that the Roman commander wept and quoted Homer's lines on the fall of Troy — "A day will come when sacred Troy shall perish" — foreseeing, he said, that Rome too would one day fall. The historian Ben Kiernan, surveying the record from the vantage of modern genocide studies, has called the destruction of Carthage "the first genocide" ¹². Whatever the exactness of that contested label, the intent was extermination and the result was the erasure of a civilisation.

A library given away, a manual kept

The cultural cost is legible in a single decision. Carthage had a literature — histories, treaties, periploi and sailing-directions, religious and legal texts, the records of a maritime civilisation six centuries deep. When the city fell, that literature was handed to the Numidian kings and vanished from history; almost nothing of Punic writing survives today beyond inscriptions, a scattering of quotations, and the fragments of a single translated farming manual. The one book the Senate chose to keep was Mago's, because Rome had estates to run ⁸¹⁰.

That is the record's hardest fact. The knowledge that survived did so not because Rome valued Carthage, but because Rome valued what Carthage knew about extracting wealth from land and sea. The naval design, the tax machine, the agronomy: Rome took the tools and destroyed the toolmaker. A civilisation was annihilated, and the fragments of it that outlived the annihilation did so in the hands, and in the service, of the power that had done the killing. When we read Columella on the care of a vineyard, we are reading, at several removes, a dead man from a burned city.

The bill, paid forward

The cost did not stop in 146 BCE. The plantation-slavery model that Mago had systematised and Rome industrialised generated its own downstream violence. The great slave estates of Sicily — the same island where Rome had first learned to run a province — erupted in the First and Second Servile Wars (135-132 and 104-100 BCE), risings of tens of thousands of enslaved agricultural workers that Rome put down with mass crucifixions. The largest slave revolt of all, led by Spartacus in 73-71 BCE, ended with six thousand captives crucified at intervals along the Appian Way from Capua to Rome. The plantation logic carried into Latin through a translated Carthaginian manual helped produce both the estates and the revolts, and the terror used to suppress them ⁵.

The deeper echo runs further still. The model of the market-oriented, slave-worked agricultural estate, transmitted and scaled by Rome, is one of the ancestors of the plantation systems that would reappear, transformed, in the medieval Mediterranean and eventually across the Atlantic world. To trace that lineage is not to collapse two thousand years into a single line — the Atlantic plantation was its own monstrous invention, with its own racial ideology — but the idea that land is best worked by owned human beings, organised for profit under management, has one of its most influential early codifications in the one Carthaginian book the Roman Senate decided was worth keeping.

What makes the transmission weigh so heavily in the long run is how durable each channel proved. The navy Rome improvised from a wreck became a permanent arm of the state and held the Mediterranean for the better part of seven hundred years. The provincial machine first assembled in Sicily governed and taxed a territory that would eventually stretch from Britain to Mesopotamia, and its basic logic — a defined territory, a resident governor, an assessed tax, a flow of revenue to the centre — outlived Rome to become part of the deep grammar of European statecraft. And Mago's agronomy remained a living authority in the Latin West until the collapse of ancient book-culture, cited and recited long after the language he wrote in had ceased to be spoken anywhere on earth. Carthage lost everything — its city, its people, its books, its gods, its very name as a living civilisation — and yet the practical core of what it knew was folded into the institutions of the power that destroyed it and carried forward for millennia. That is the paradox the record exists to hold: annihilation and inheritance, in the same act ⁹.

Rome's transformation into a Mediterranean empire was, to a striking degree, a programme of copying its greatest rival: its ships, its provincial machine, its agricultural science. The transmission was real, and its consequences run through the whole of Roman and European history. But the mechanism was conquest, and the consummation was erasure. Carthage taught Rome how to rule the sea, tax a province, and farm an estate — and every part of that teaching was extracted from a city that Rome, having learned what it needed, ground into the ground.
