Saint Charles Borromeo is invoked as patron of bishops. Charles Borromeo was born on October 2, 1538, at the family castle of Arona on Lake Maggiore, the second son of Count Giberto Borromeo and Margherita de' Medici. After studies in canon and civil law at the University of Pavia, where he received his doctorate in 1559, his maternal uncle was elected Pope Pius IV in December of that year.
