5th-century Gallic poet, diplomat, bishop, and Catholic saint
Gaius Sollius Modestus Apollinaris Sidonius, better known as Sidonius Apollinaris, was a poet, diplomat, and bishop. Born into the Gallo-Roman aristocracy, he was son-in-law of Emperor Avitus and was appointed Urban prefect of Rome by Emperor Anthemius in 468. In 469 he was appointed Bishop of Clermont and he led the defence of the city against attacks from the armies of Euric, King of the Visigoths, from 473 to 475. He regained his position as bishop, after the city's conquest, and retained it until his death in the 480s. He is venerated as a saint in the Catholic church, the Orthodox Church, and the True Orthodox Church, with his feast day on 21 August.
