De agri cultūra or De re rustica (‘on agriculture’), treatise by M. Porcius Cato the Censor, the oldest piece of Latin prose of some length to survive. It is a concise, practical handbook, dealing with the cultivation for profit, in Latium and Campania, of vines, olives, and fruit, and with cattle-breeding. Cato discusses the purchase of a farm; the duties of owner, overseer, housekeeper, and slaves; the tilling of the soil; the care of livestock; and a few minor matters, such as a prescription for treating a sick ox, recipes for curing hams and making cheese-cakes, and religious and superstitious formulas. It is written in a curt, abrupt style, without much organization of material, but it was widely read and quoted from in ancient times.
