LUCIUS JUNIUS MODERATUS, a celebrated Roman writer on agriculture, was a native of Cadiz, and lived under the emperor Claudius. He composed his works about the year 42 of our era. These consist of a treatise on agriculture, entitled De Re Rustica, and another De Arboribus. The treatise De Re Rustica is divided into twelve books, of which the tenth is in verse; that De Arboribus is ordinarily printed along with the former, in which case it forms a thirteenth or supplemental book. The first edition is that of Jenson, Venice, 1472, folio, very rare, under the title Rei Rusticae Authores varii, Cato, Varro, Columella, Palladius Rutilius; the second, that published at the same place in 1482, folio; the third, that of Bologna, with explanations and commentaries by Be-roaldus, 1494, folio. But the most complete and accurate edition is that of Gesner, entitled Rei Rusticae Scriptores veteres Latini, cum notis variorum, et ex novo Matth. Gesneri recensione, Leipzig, 1735, two vols. in 4to. The two works of Columella were printed separately, at Strasbourg in 1543, 8vo; at Lyons in 1548, 8vo; and at Bologna, with interpretations by Bio, in 1520, folio. They have been translated into the German, the Italian, and the French.
