According to their legend, their
relics were discovered in a
cave near Besançon in AD 370 by a military
tribune whose dog was chasing a
fox. The relics were enshrined by Bishop Anianus of Besançon in the 4th century AD. Ferreolus appears in a catalogue of the 17th century as a bishop of Besançon, but the
liturgy of Besançon has always remembered Ferreolus as a priest, and Ferrutio as a deacon. Ferreolus and Ferrutio, as patrons of Besançon, are considered to have appeared on the
city walls in times of danger. The two saints have been represented in
stained glass,
paintings, and
statues in many churches and chapels in the two dioceses of the
Franche-Comté:
Saint-Claude and
Besançon. The
Basilique Saint-Ferjeux is situated in the neighborhood of Saint-Ferjeux, Besançon. They are depicted on a French lantern slide dating from AD 1900. ==Butler's account==
