BARONTIUS and DESIDERIUS (Saints) (May 25) Hermits. (8th century) Saint Barontius was a married French nobleman of Berri, who, together with his son, leaving the Court of King Thierry II, retired into the Abbey of Saint Cyran near Nevers. He afterwards migrated into Italy and took up the life of a hermit in the hill country near Pistoja in Tuscany. He was joined by Saint Desiderius and others. He died in A.D. 700, or a year or two later.
