The ancient agrarian writers (or agronomists) wrote manuals on the practice of farming. Though often categorized as technical literature, the principal surviving examples – Cato's
De agri cultura
, Varro's
Res rusticae,
and Columella's
De re rustica
– all demonstrate literary self‐conscious, and in Varro and Columella this is highly developed. The genre was always highly moralizing, and concerned at least as much with elite self‐fashioning as providing practical guidance to agriculturalists. But it does provide important insights into the economics and technological practices of ancient farming.
