John Righi was a 15th-century Italian Franciscan friar and priest who lived a life of asceticism. Born into a noble family in Fabriano around 1469, he joined the Order of Friars Minor in 1484. He later spent his later years as a hermit in Cupramontana, where he gained a reputation for preaching and healing the sick. His spiritual influence was significant, as his sermons encouraged many people to repent or return to the Catholic faith.
