He, who in the third century planted the faith with great zeal in Auvergne, and died a holy confessor, is also honoured on this day. His head is preserved in the abbey which bears his name at Issoire in Lower Auvergne; the rest of his relics chiefly in the abbey of Mauzac near Riom; and at Pierre-Encise or Saint Guoine in Aquitain. His name was famous in France in the eighth century, and is mentioned in the Roman Martyrology. See Saint Gregory of Tours. Mabillon has published the history of the translation of his relics to Mauzac.
