Roman agriculture describes the farming practices of ancient Rome, during a period of over 1000 years. From humble beginnings, the Roman Republic (509 BC to 27 BC) and the Roman Empire (27 BC to 476 AD) 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 winter 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.
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.
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" (parsimonia, diligentia, iustitia).
