Saint Cizy de Rieux

Cizy, or Saint Cizy of Rieux (8th or 9th century), a member of the family of the Dukes of Burgundy, was a soldier of Charlemagne (possibly under the command of Saint Vidian) and a native of Besançon. He was taken prisoner by Muslims arriving from Spain. He refused to abjure his Christian faith or embrace the religion of Muhammad and was martyred at the foot of the city of Angonia (modern-day Martres-Tolosane), near Rieux-Volvestre in Haute-Garonne, of which he is the patron saint. He is a Christian saint whose feast day is August 16. The Cathedral of Rieux preserves a reliquary containing a tooth set in a silver cylinder.
