Biography
Ursus is an Italian saint of the 6th century. His feast day is February 1 (June 17 in some areas). The collegiate church of Saint Ursus in Aosta was built by and dedicated to him.

Said to have been of Irish origin, he evangelized the region of Digne. An opponent of Arianism, he served as archdeacon to (in Italian, San Giocondo; in French, Saint Joconde), bishop of Aosta. When Plocean, an Arian, became bishop of Aosta, Ursus and several other canons left the cathedral of Aosta and established themselves at the present site of the collegiate church of Saint Ursus.
