Orientius was a fifth-century Christian Latin poet and archbishop who lived in the regions of Urgell and Auch. Born around 302, he is believed to have undergone a conversion following a sinful youth. As an experienced pastor, he composed religious literature during a period when Gaul faced significant devastation from barbarian invasions. He is identified as the bishop of Augusta Ausciorum, who served as an ambassador for King Theodoric I to Roman generals in 439.
