Aredius, also Yrieix, Abbé d'Attanum and Arède d'Atane, was chancellor to Theudebert I, king of Austrasia, and later Abbot of Attane. He founded the monastery of Attane, which was renamed after his death Saint-Yrieix in his honour. The town at the site became known as Saint-Yrieix-la-Perche. Several other French communes are also called Saint-Yrieix after him.
