Altigianus and Hilarinus were monks of the French Burgundian monastery of Saint-Seine founded two centuries earlier by Saint Sequanus. The Moors who had invaded Spain in the early eighth century spread their conquest for a time into parts of France, and penetrated the country all the way to the Burgundian city of Autun. Their advance was not halted until 732, when the Frankish ruler Charles Martel defeated them between Poitiers and Tours. It was about this time that Altigianus and Hilarinus were slain with the sword by the Moors at or close to the Saint-Seine monastery, not far from Autun.
