The seventeenth-century Benedictine scholar Jean Mabillon accepted the traditional founding of Fleury as by Leodebaldus, abbot of St-Aignan (Orléans) about 640, in the existing Gallo-Roman villa of Floriacum, in the Vallis Aurea, the "Golden Valley". This was the spot selected by the Abbot of St-Aignan for his Benedictine foundation. Rigomarus was its first abbot.
