PETRONACE of MONTECASSINO. - Died at Montecassino on 6 May 750. At the behest of Gregorio II, he was abbot of that same monastery, to which he came as a pilgrim from his native Brescia and which he rebuilt and reorganized, with the help of some Benedictine brethren from Rome and others from S. Vincenzo al Volturno, in 718.
Among his most illustrious disciples were the Frankish king Carlomanno (748) and the Lombard king Rachis (749). The very founder of the abbey of Fulda, Stazio di Baviera, wished to spend a year of spiritual perfection under P.; P. also had the consolation of seeing among his devotees the very successor of the ancient destroyer of the monastery, Gisulfo II, duke of Benevento, who came to the now celebrated abbey to repair the harm done by his ancestor Zotone in 589.
