The most famous medieval agricultural treatise, and, apart from the Bartholomaeus Anglicus's De proprietatibus rerum, the earliest non-classical work to deal with agriculture and viticulture. The author, a successful Bolognese attorney, retired to his estate in 1299 where he wrote this agricultural handbook, finished in 1305. The survival of 91 medieval Latin codices of Ruralia commoda confirm its wide distribution in the period before print. Nine Latin editions and three editions in German appeared in print before 1500.
