St. Cajetan (1480-1547), who was born Gaetano da Thiene, was one of the earliest Italian Catholic reformers of the 16th century. He was a cofounder of the Clerks Regular, a religious order popularly known as the Theatines.
The Italian reformer St. Philip Neri (1515-1595) is known as the Apostle of Rome. With his distinctly joyous and personal manner, he was one of the influential figures of the Catholic Reformation. His special contribution was the creation of the Congregation of the Oratory.
