Decimius Magnus Ausonius was a prominent Gallo-Roman poet and rhetorician from Burdigala in the 4th century AD. He served as a tutor to the future emperor Gratian, which elevated him to high positions within the Western Roman Empire, including the praetorian prefecture and consulship. His literary works are diverse, encompassing epigrams, elegies, and occasional verses that provide valuable insight into the life and culture of late antiquity. His most famous poem, the Mosella, is a descriptive work celebrating the Moselle River and its surrounding landscape.
