Upon the death of his father, Aredius returned to the Limousin to care for his mother. Entrusting to her the management of his estates, he lived for a time as a hermit in a cave. He founded, between 564 and 572, the monastery of Attane on the land of his inherited estate, located on the rivers
Loue and Couchou in Haute-Vienne. He was the first abbot of the monastery, and the earliest monks were members of his own household. Gregory of Tours says that the house followed the rule of Saint
John Cassian and later incorporated some aspects of the rule of Saint
Basil of Caesarea. Later, other monks joined them. The site of the monastery was to give rise to the city of
Saint-Yrieix-la-Perche. Aredius divided his time between agricultural labor and study. He was known for his evangelical journeys throughout Gaul. He founded monasteries in Vigeois and Excideuil in Périgord and went on pilgrimages, always on foot. Every year he made a pilgrimage to Tours to celebrate the feast of Saint
Martin of Tours. He would also travel annually to the
Holy Cross Abbey in Poitiers to visit Queen
Radegund. He supported the cult of
Medardus of Soissons and probably built the church in his honour at Excideuil. Aredius built several churches in honour of saints whose relics he had collected. ==Hagiography and relics==
