A nobleman of Berry,[2] he studied at Tours and then joined the royal court of Clothaire II.
[2] His father, count of Bourges (and later bishop of Tours), wanted Sigiramnus to marry the daughter of a nobleman.
[2] He refused to gain high position in the secular world, and after his father died, he gave away his goods and money to the poor; he was locked away as a lunatic for this.
[2][3] According to one account, as they crossed the diocese of Tours, he insisting on working in the fields with the serfs after he was “seized with compassion at the peasants covered with dust and sweat.”[3] When Sigiramnus returned to France, he founded two monasteries with land given to him by Clothaire in the diocese of Bourges: Saint-Pierre de Longoret (Longoretum, Lonrey) and Méobecq (Millepecus), in the forest of Brenne region of the Berry province.
[3] Sigiramnus’ relics were kept at the abbey of Saint-Cyran until 1860, when Eugénie de Montijo, Empress consort of the French, encased them in a reliquary and gave it to the church of Saint-Michel-en-Brenne.
