Fabrizio (Augustino) Caracciolo was born in 1555 in Naples. As a young man he revealed himself as being readily disposed to learning as well as piety. He completed his studies by obtaining a degree in Law, and he decided at that young age to pursue an Ecclesiastical career. He became successful in his career and at that time he had titles and Ecclesial benefits of the Abbey in Marsico Vetere in Naples. He met Agostino Adorno and Saint Francis Caracciolo in 1587 in Naples and they began the founding of a new Religious Institute in the Church. It was him who provided the needs of the newly found Religious Order in its beginnings by his income as the Abbot of Saint Mary Major Church in Naples. After renouncing all his personal and family possessions, he made his Solemn Profession on the feast of Saint Bartholomew the Apostle, on August 25, 1596. It was on this occasion that he changed his name to Augustino in memory and in appreciation of his Co-Founder of the Institute. He died as a simple and humble religious on May 25, 1615 at age 60.
