Saint Ubald (Ubaldo) of Gubbio (†1160) was a medieval bishop of Gubbio, in Umbria, today venerated as a saint by the Catholic Church. Numerous miracles were attributed to him during his life and after his death. Pope Celestine III canonized him in 1192. His power, as we read in the Office for his feast, is chiefly manifested over the evil spirits, and the faithful are instructed to have recourse to him "contra omnes diabolicas nequitias" (against all the devil's assaults). He is the Holy Patron of Gubbio, Italy; against demonic possession; migraine, neuralgia, sick children; autistics; and people with obsessive-compulsive disorder. His feast is commemorated on May 16th.
