The Roman poet and politician Decimus Magnus Ausonius (310-395) was born in Burdigala (Bordeaux) in Rome to a wealthy family. He was the tutor of the later Roman Emperor Gratian (359-383), who later appointed him consul in Augusta Treverorum (today's Trier), the Roman administrative capital of Gaul. It was here that the Romans established viticulture. Ausonius owned a vineyard of about 1,100 acres in Lucaniacus on the Garonne in what is now the Saint-Émilion area. It is possible that the Château Ausone named after him is located there today or, according to more recent findings, perhaps the Château La Gaffelière, which also claims this place. He also wrote a detailed description of the wines of the Gironde. He also praised the wines from the Burgundian Mâconnais.
