Austromoine was a 3rd-century bishop of Clermont, often referred to as the apostle of Auvergne. According to the writings of Gregory of Tours, he was one of seven bishops sent from Rome to Gaul by Pope Fabian around 250 AD to spread the Gospel. During his mission, he is credited with converting local figures such as the senator Cassius and the priest Victorinus. He eventually faced martyrdom by beheading in the region of Clermont-Ferrand.
