Angelo Rocca is also known as Camers Camerinus from the Augustinian monastery at Camerino. He studied at Perugia, Rome and Venice. In 1577 he graduated as doctor in theology from Padua. After serving as superior-general of the Augustinian Monastery there from 1579, he become the head of the Vatican printing-office in 1585. In 1595 he was appointed sacristan in the papal chapel. In 1605 he was granted the office of titular Bishop of Tagaste in Numidia (the historic Augustinian diocese).
He was a researcher of history. He edited the printed version of the Vulgate Bible, (widely unknown before the printing press) and had it printed. During the editing he became accustomed with historic manuscripts stored in Vatican – some of them not readily accessible until modern times. He (incorrectly) credited St. Jerome with the invention of Glagolitic.
