Agriculture in ancient Rome


Roman agriculture describes the farming practices of ancient Rome, during a period of over 1000 years. From humble beginnings, the Roman Republic and the Roman Empire expanded to rule much of Europe, northern Africa, and the Middle East and thus comprised many agricultural environments of which the Mediterranean climate of dry, hot summers and cool, rainy winters was the most common. Within the Mediterranean area, a triad of crops were most important: grains, olives, and grapes.
The great majority of the people ruled by Rome were engaged in agriculture. From the beginning of small, largely self-sufficient landowners, rural society became dominated by latifundium, large estates owned by the wealthy and utilizing mostly slave labor. The growth in the urban population, especially of the city of Rome, required the development of commercial markets and long-distance trade in agricultural products, especially grain, to supply the people in the cities with food.

Background

The main texts of the Greco-Roman agricultural tradition are mostly from the Roman agronomists: Cato the Elder's De agri cultura, Columella's De re rustica, Marcus Terentius Varro and Palladius. Attributed to Mago the Carthaginian, the agricultural treatise Rusticatio, originally written in Punic and later translated into Greek and Latin, is now lost. Scholars speculate whether this text may have been an early source for agricultural traditions in the Near East and Classical world.

The "delightful" life

Agriculture in ancient Rome was not only a necessity but was idealized as a way of life. Cicero considered farming the best of all Roman occupations. In his treatise On Duties, he declared that "of all the occupations by which gain is secured, none is better than agriculture, none more profitable, none more delightful, none more becoming to a free man." When one of his clients was derided in court for preferring a rural lifestyle, Cicero defended country life as "the teacher of economy, of industry, and of justice". Cato, Columella, Varro and Palladius wrote handbooks on farming practice.
In his treatise De agricultura, Cato wrote that the best farms contained a vineyard, followed by an irrigated garden, willow plantation, olive orchard, meadow, grain land, forest trees, vineyard trained on trees, and lastly acorn woodlands. Though Rome relied on resources from its many provinces acquired through conquest and warfare, wealthy Romans developed the land in Italy to produce a variety of crops. "The people living in the city of Rome constituted a huge market for the purchase of food produced on Italian farms."
Land ownership was a dominant factor in distinguishing the aristocracy from the common person, and the more land a Roman owned, the more important he would be in the city. Soldiers were often rewarded with land from the commander they served. Though farms depended on slave labor, free men and citizens were hired at farms to oversee the slaves and ensure that the farms ran smoothly.

Crops

Grains

Staple crops in early Rome were millet, and emmer and spelt which are species of wheat. According to the Roman scholar Varro, common wheat and durum wheat were introduced to Italy as crops about 450 BC. Durum wheat became the preferred grain of urban Romans, because it could be baked into leavened bread and was easier to grow in the Mediterranean region than common wheat. Grains, especially baked into bread, were the staple of the Roman diet, providing 70 to 80 percent of the calories in an average diet. Barley was also grown extensively, dominating grain production in Greece and on poorer soils where it was more productive than wheat. Wheat was the preferred grain, but barley was widely eaten and also important as animal feed.
In De re rustica Columella wrote that emmer was more resistant to moisture than wheat. According to Columella four types of emmer were cultivated, including one variety that he calls Clusian. Cato wrote that if sowing grain in humid or dewy soils was unavoidable, they should be sown alongside turnips, panic grass, millet and rapeseed.
Despite listing panicum and millet among the legumes Columella says they should be considered grain crops "for in many countries the peasants subsist on food made from them".

Legumes

Of legumes, Columella lists some that are preferred for cultivation: lentils, peas, lupinus, beans, cowpeas, and chickpeas.
He writes the following about lupinus:
...it requires the least labor, costs least, and of all crops that are sown is most beneficial to the land. For it affords an excellent fertilizer for worn out vineyards and ploughlands; it flourishes even in exhausted soil; and it endures age when laid away in the granary. When softened by boiling it is good fodder for cattle during the winter; in the case of humans, too, it serves to warn off famine if years of crop failures come upon them.

Olives

The Romans grew olive trees in poor, rocky soils, and often in areas with sparse precipitation. The tree is sensitive to freezing temperatures and intolerant of the colder weather of northern Europe and high, cooler elevations. The olive was grown mostly near the Mediterranean Sea. The consumption of olive oil provided about 12 percent of the calories and about 80 percent of necessary fats in the diet of the average Roman.

Grapes

Viticulture was probably brought to southern Italy and Sicily by Greek colonists, but the Phoenicians of Carthage in northern Africa gave the Romans much of their knowledge of growing grapes and making wine. By 160 BC, the cultivation of grapes on large estates using slave labor was common in Italy and wine was becoming a universal drink in the Roman empire. To protect their wine industry, the Romans attempted to prohibit the cultivation of grapes outside Italy, but by the 1st century AD, provinces such as Spain and Gaul were exporting wine to Italy.

Fodder

Columella mentions turnips as important, high-yielding food crop, especially in Gaul where they were used as winter fodder for cattle. As other "fodder crops" he lists Medic clover, vetch, barley, cytisus, oats, chickpea and fenugreek. Of Medic clover, he says it improves the soil, fattens lean cattle and is a high-yielding fodder crop.
Cato the Elder wrote that leaves from poplar, elm and oak trees should be gathered in the Fall before they have dried completely and stored for use as fodder. Turnips, lupines and forage crops were to be sown after the rainy season.

Other crops

The Romans also grew artichoke, mustard, coriander, rocket, chives, leeks, celery, basil, parsnip, mint, rue, thyme "from overseas," beets, poppy, dill, asparagus, radish, cucumber, gourd, fennel, capers, onions, saffron, parsley, marjoram, cabbage, lettuce, cumin, garlic, figs, "Armenian apricots," plums, mulberries, peaches, and hemp.

Storage

describes how produce is stored and gives advice to prevent spoilage. Liquids produced for market like oil and wine were stored on the ground floor and grain was stored in lofts with hay and other fodder. He instructs that granaries be well ventilated, cool, with minimal humidity, to prolong freshness. He describes certain methods of construction to avoid buildings developing cracks that would give animals and weevils access to the grains.
Press rooms, he advised, should be warm receiving light from the south to prevent the oil from freezing, which makes oil spoil faster.

Land

Columella describes land as being classified into three types of terrain which he calls champaign, hills with a gradual but gentle rise, and wooded, verdant mountain highlands. Of soil, he says there are six qualities: fat or lean, loose or compact, moist or dry. The permutations of these qualities producing many varieties of soils. Columella quotes Vergil's comment that loose soil is "what we rival when we plough". Of the most preferred types of soil he says the best is fat and loose soil that is the least costly and most productive, then fat and dense which is productive though requiring more effort, and after these are the moist soils.

Religious Practices and Agricultural Deities

Agricultural success in ancient Rome was closely linked with religious observance. The Romans worshipped a pantheon of agricultural deities, including Ceres, the goddess of grain and fertility, and Saturn, the god of sowing and time. Festivals such as the Cerialia were held in honor of Ceres, and the Saturnalia celebrated agricultural bounty and social inversion. These events were marked by sacrifices, games, and communal feasting, symbolizing the Romans’ belief in divine favor as essential to successful farming.

Tools and Techniques

Roman farmers used a variety of tools, including the ard, sickles, and hoes. These tools were typically made of wood with iron tips. Innovations such as crop rotation and the use of organic fertilizers were employed to maintain soil health. In dry regions, farmers constructed irrigation ditches and cisterns to manage water resources efficiently.

Agricultural Economy and Trade

The Roman economy was largely agrarian, with wheat, barley, olives, and grapes being staple crops. Grain was especially crucial, with major supply centers in Sicily, Egypt, and North Africa. Olive oil and wine became major export goods, transported via Rome’s extensive road and maritime trade networks. These products were traded across the empire, facilitating both economic and cultural exchange.

Slavery and Agricultural Labor

Slave labor was integral to Roman agriculture, especially on latifundia, large estates owned by the elite. These estates relied on enslaved people for planting, harvesting, and processing crops. The use of forced labor enabled vast agricultural output but also contributed to increasing economic inequality and social unrest.
