Columella

Lucius Junius Moderatus Columella was a Roman writer on agriculture, born in Gades, the modern Cádiz, in the province of Hispania Baetica. He lived in the first century AD, under the Empire, and wrote in Latin. His surviving work is the most complete account we have of Roman farming, and it remains a key source for the crops, techniques and rural life of his day.

Little is known about his personal life. He served in the army and, by most accounts, was a tribune in Syria around the year 35. He later settled in Italy, where he managed his own estates at Ardea, Carseoli and Alba in Latium, and tested in practice what he would later write about. An uncle, Marcus Columella, a farmer in Baetica who experimented with breeding sheep, may have sparked his interest in the subject.

His main work, De re rustica, runs to twelve books and is addressed to Publius Silvinus, a neighbour of one of Columella's farms. It covers everything from choosing land and organising an estate to vineyards, fruit trees, large and small livestock, poultry, beekeeping, gardens and the duties of the farm worker. Book ten is written in hexameter verse, as a reply to Virgil's Georgics, where the poet laments that he cannot write about gardening. Columella drew on earlier authors such as Cato the Elder and Varro, as well as Greek and Carthaginian sources, including the agronomist Mago. In his preface he complains that farming, so close to wisdom, has few students and fewer teachers. For him, working the land also carried traditional virtues of restraint, persistence and discipline.

The short De arboribus, on trees and shrubs, is usually attributed to him, although some scholars think it was a separate and possibly earlier text. He also wrote other works that are now lost, including pamphlets against astrology.

In antiquity his work circulated only modestly. A few authors cited it, and Palladius produced a shorter treatise based on it. The complete text resurfaced in monastery libraries in Switzerland and France around 1414 to 1418, and humanists took it up with enthusiasm. His ideas shaped Renaissance agronomy and influenced Spanish writers such as Gabriel Alonso de Herrera. Today he is remembered as the most thorough voice on Roman agriculture.
