PALLADIUS, Rutilius Taurus Aemilianus, a Roman writer on agriculture, probably flourished in the fourth century. The only record of his life and labours is a treatise, De Re Rustica, in fourteen books. The first book introduces the subject, the twelve next treat of the agricultural operations of the twelve months of the year, and the last describes in elegiac verse the art of grafting. The work rose to high repute in the middle ages. It appears to have been often transcribed; and it was nearly completely incorporated in the Speculum of Vincent of Beauvais. In modern times editions have appeared by Ernesti, in 1773; and by Schneider, in his Scriptores Rei Rusticae, 4 vols. 8vo, Leipzig, 1794. Among the various translations into different languages is the English version of T. Owen, 8vo, London, 1807.
