Arsenio from Trigolo, born Giuseppe Antonio Migliavacca, was an Italian Catholic priest and member of the Order of Friars Minor Capuchin. Born in 1849, he initially served as a Jesuit before leaving the order due to various complications and personal difficulties. He later founded a congregation of nuns, though he was eventually forced to step away from that community following accusations. He ultimately found his vocation within the Franciscan tradition, serving as a preacher and confessor in Bergamo until his death in 1909.
