The Roman author Rutillius Taurus Aemilianus Palladius (Palladii Rutilii Tauri) lived in the 4th or 5th century, but little is known about his life. He farmed and owned estates in Italy and Sardinia. Palladius wrote the 15-volume work "De re rustica" (On Agriculture). The works of Varro (116-27 BC), Pliny the Elder (23-79 AD) and especially Columella (1st half of 1st century) are used as sources. The first book is a general introduction to agriculture, the last two contain instructions on veterinary medicine and grafting. The remaining twelve books describe the necessary agricultural work, one volume for each month. In these, almost all crops are treated, with the vine being treated most extensively. Among other things, he also describes the production of the honey wine Mulsum. Palladius' work had great importance beyond the Middle Ages until the Renaissance. He is cited by Albertus Magnus (1200-1280), as well as the wine authors Petrus de Crescentiis (1230-1320) and Johann Rasch (1540-1612). See also under Ancient Grape Varieties and Antique Wines.
