St. Alexander Sauli was the apostle of Corsica and bishop. At an early age he entered the Barnabite Congregation, and became a teacher at the University of Pavia and superior general of the congregation. In 1571, he was appointed by Pope St. Pius V to Aleria on the island of Corsica. Taking three companions, they rebuilt churches, founded seminaries and colleges, and stood off the pirate raids in the area. He became the bishop of Pavia, serving only a year before his death. St. Alexander was a noted miracle worker and the spiritual adviser to St. Charles Borromeo and Cardinal Sfondrato, who became Pope Gregory XIV.
