Sigiramnus

"Sigirannus” is also the name of a 7th-century abbot of St. Cales in the department of Sarthe. Sigiramnus (also Sigirannus and similar spellings; ; died 655 AD), also known as Saint Cyran, was an abbot and confessor of the 7th century. A nobleman of Berry, he studied at Tours and then joined the royal court of Clothaire II.

Refusing to marry, Sigiramnus took holy orders at the church of St. Martin at Tours in 625 AD, serving as archdeacon at Tours.

Longoret was later renamed Saint-Michel-en-Brenne after him. He served as abbot of Longoret until his death in 655 AD.

Veneration A life of Sigiramnus was written in the ninth or tenth centuries; the author of this Life claims to have compiled it from an earlier text.

The monastery of Saint-Cyran was dissolved in 1712. Jean du Vergier de Hauranne (1581–1643), known as the Abbé of Saint-Cyran, took his title from this monastery.

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.
