The city was razed to the ground (the famous salt is a later myth; ancient sources say nothing about it), and translators were immediately sent in to sort through the surviving books of the defeated enemy. This is a story about how knowledge outlives those who created it.
146 BC — a date remembered for the scale of the destruction. The Third Punic War ended as Cato the Elder had, in fact, intended it to end: Carthage ceased to exist. The city burned, according to various accounts, for as long as seventeen days. Those inhabitants not killed in the assault were sold into slavery. The territory was declared the province of Africa. Rome gained the fertile lands of what is now Tunisia, control of trade routes and — far less obviously — access to the intellectual legacy of Phoenician-Punic civilization.
Among the spoils — or, more precisely, among what the Roman Senate considered worth preserving — was an agricultural treatise by a certain Mago. We know almost nothing about the author himself: neither his exact dates, nor his office, nor whether he was a working landowner or an armchair compiler. His name was Punic, fairly common in Carthage; Carthaginian history has no shortage of generals and suffetes bearing it. But this Mago became famous for something else: he wrote, in Punic, a treatise on agriculture running to 28 books (some sources say 32, and that discrepancy itself says something about just how unreliable our information is).
The Senate’s decision to translate the treatise is a fact attested by Pliny the Elder in his Natural History. The decision looks paradoxical in the context of what Romans usually did with the cultural inheritance of conquered peoples. The Senate distributed the libraries of Carthaginian aristocrats among allied Numidian petty kings — a gesture more political than cultural. Out of all Carthage’s literary wealth, one work was deliberately saved. One — but precisely the one that taught people how to cultivate the land properly.
The Latin translation was entrusted to Decimus Junius Silanus, a man about whom we know even less than we do about Mago himself. His name points to membership in the Junii — an ancient and sprawling Roman family. Silanus knew Punic, a skill that was uncommon in Rome in the mid-2nd century BC but not exotic: commercial ties with Carthage had lasted for centuries, and the Punic Wars had produced an entire stratum of people who dealt with Punic speakers as translators, diplomats, and spies.
What fascinates me is the sheer scale of the task. Twenty-eight books is no pamphlet. Punic, related to Phoenician and Hebrew, was written in a consonantal script, without vowels; translating it into Latin also demanded subject-matter expertise. Silanus had to understand what Mago was writing about — otherwise the agricultural terminology would have turned into nonsense. We do not know whether he worked alone or with a group of assistants, how many years the translation took, or how freely he handled the original. Not a single line of this Latin translation has come down to us directly — only reflections in the mirrors of later writers.
Alongside the Latin translation, a Greek adaptation emerged. Cassius Dionysius of Utica — a Greek from the city of Utica, near the ruins of Carthage — recast Mago’s legacy in Greek: of the 20 books of his Georgics, by Columella’s count, only eight retell Mago himself. The work was dedicated to the praetor Sextilius around 89–88 BC. Later, Diophanes of Nicaea abridged this version even further, to 6 books. Each stage of adaptation was a filter: something was added from the Greek agricultural tradition, something was lost, the emphasis shifted. When we read “Mago said,” we are really reading a quotation from a quotation from a translation of a translation.
Despite all these layers of mediation, the fragments of the treatise scattered through the works of Varro, Columella, Pliny, and the later compiler Gargilius Martialis make it possible to sketch at least an approximate map of the subjects that occupied the Carthaginian agronomist.
One of Mago’s best-known pieces of advice — preserved precisely because it struck Roman writers — is addressed to someone who has bought a country estate: sell your town house. The logic is hard and pragmatic: whoever lives in the city does not tend the land properly. An estate needs an owner who walks it on his own feet, not someone who manages through intermediaries. Columella quotes this advice with clear approval — for a Roman of the 1st century AD, absentee landownership was a painfully current problem.
Viticulture held a prominent place in the treatise. Mago described techniques for planting and tending vines and — especially valuable — left a recipe for passum, a sweet wine made from partially dried grapes. The method involved drying the clusters in the sun to a certain point, then fermenting must with a high sugar concentration. This kind of wine was well known throughout the Mediterranean, and it is impossible to claim that Mago invented it — but his description proved detailed and authoritative enough for Roman authors to cite it centuries later.
Olive trees were another major subject. North Africa remains one of the key olive-growing regions to this day, and in Punic times Carthaginian territory was famed for its oil. Mago apparently offered recommendations on selecting soils for olives, as well as on planting and pruning times. He also wrote about horticulture in a broader sense — fruit trees, grain crops, and legumes — though the surviving fragments here are exceedingly sparse.
Animal husbandry was extensively covered in the treatise: oxen, mules, horses, and questions of livestock health. Beekeeping, too, fell within its scope. And finally, estate management as a system — assigning work by season, organizing labor, dealing with workers. In essence, Mago described agriculture as an integrated enterprise.
Here we need the kind of honesty that popular retellings of this story often lack. The temptation is great: to declare Mago the father of all Roman agronomy, to say that Rome “stole” Punic technologies and built its agricultural might upon them. A handsome scheme — but it does not stand up to scrutiny.
First, Mago’s treatise was not the only source of agricultural knowledge in the ancient world. The Greek tradition of agricultural writing existed long before the fall of Carthage. Hesiod was already writing about farm work in the 8th–7th centuries BC. Greek authors — Theophrastus, the disciples of the Peripatetic school — produced an extensive body of botanical and agronomic texts. The Romans also had practical experience of their own: Italy was not a tabula rasa waiting for Punic revelation.
Second, we cannot verify how accurate Roman authors’ quotations from Mago are. Columella and Pliny, when citing him, may have attributed to him material that came from the Greek adaptations of Cassius Dionysius or Diophanes. They may have altered his recommendations, adapting them to Italian conditions. The difference between “Mago wrote” and “Mago wrote something that, after two translations and a hundred years of retelling, turned into this” is fundamental.
Third, the Senate’s decision to commission a translation, for all its symbolic power, does not mean Roman agriculture before 146 BC was primitive. Cato the Elder — the very man who demanded Carthage’s destruction — wrote his treatise De agri cultura roughly fifteen years before Carthage fell. Cato drew on Italian experience and Greek sources. Rome was already an agrarian power; Mago’s work supplemented existing knowledge rather than creating it from scratch.
What we can state with certainty is this: the Roman Senate considered Mago’s treatise valuable enough to commission a state translation. That is a fact. Roman agronomists cited Mago as an authority for several centuries. That is also a fact. But between “an authoritative source” and “the only source” lies a distance that should not be shortened for the sake of a prettier narrative.
It seems to me that the most interesting thing in this story is the very act of translation (strictly speaking, we know the contents of the treatise only in fragments).
Rome fought three wars with Carthage over more than a hundred years. Hannibal stood at the gates of Rome. The Punic Wars were an existential conflict: not a border skirmish, but a struggle over who would dominate the western Mediterranean. Hatred for Carthage ran so deep that the formula “Ceterum censeo Carthaginem esse delendam” became a symbol of implacability. And then — the city is destroyed, its population exterminated or enslaved, its land cursed. Yet some time after this, that same Senate which sanctioned the destruction orders a careful translation of a Carthaginian book on how to plant olive trees properly.
This was not humanism, nor was it love of knowledge in any elevated sense. It was pragmatism — cold, calculating pragmatism. Rome had acquired vast territories in North Africa, and those territories had to be exploited. Who knew better how to grow grain and olives in African soil than those who had done it for centuries? The Carthaginians were gone — but their knowledge could work for their new masters. In this context, Mago’s book was not a monument to a defeated culture, but a manual for exploiting seized property.
And yet — even if the motive was purely utilitarian — the result was broader than the intention. Mago’s treatise entered the Roman agricultural tradition. Fragments of Punic knowledge, translated into Latin, retold in Greek, quoted by Pliny and Columella, survived into medieval compilations. The author has long been dead, his city is ruins, his language forgotten, and yet the recipe for passum is still being read.
Ancient agronomy did not develop in isolated national containers. It was, roughly speaking, a joint project of several civilizations that nevertheless regularly went to war with one another.
The Phoenicians who founded Carthage brought with them from the Levant their experience in viticulture and olive cultivation. On African soil, that experience was transformed, enriched through contact with local Libyan and Berber practices. Mago — if he truly was a systematizer rather than merely a compiler — gathered this knowledge into a text. Greeks living in Sicily and southern Italy exchanged not only sword blows with the Carthaginians for centuries, but grape varieties as well. Cassius Dionysius, a Greek from Punic Utica, was a living embodiment of this entanglement: a man with a Greek name, living in a Carthaginian city, translating a Punic text into Greek and dedicating it to a Roman praetor.
Varro, in his treatise De re rustica (37 BC), lists the authors he considers his predecessors: among them are Greeks and Mago the Carthaginian. Varro saw no contradiction in learning from an enemy. Columella, writing under Nero, goes further still: he calls Mago “the father of agricultural science” — a phrase that certainly exaggerates, but reflects genuine respect for the Punic tradition two centuries after Carthage’s destruction.
Knowledge moved through the Mediterranean most often as booty. Rome absorbed Greek philosophy along with Greek enslaved teachers. Rome absorbed Carthaginian agronomy along with Carthaginian land. The mechanism of transmission was harsh, sometimes cruel — but it worked. Mago’s text passed through the hands of a Latin translator, a Greek adapter, two or three generations of Roman writers quoting it, and became something impossible to attribute to any one culture alone.
The last direct references to Mago appear in Gargilius Martialis in the 3rd century AD — four hundred years after the translation. Then those texts, too, began to crumble away. Of twenty-eight books, all that remain are scattered quotations, retellings of retellings, shadows of shadows. But the fact itself — that the victorious Senate commissioned a translation of the defeated people’s book — survived, and it says, perhaps, more about Rome than any triumphal relief.
