The New International Encyclopædia…
“ A Benedictine monastery, at one time among the richest and most famous of Italy, situated not far from Rome. It was founded in the middle of the sixth century by Saint Laurence, Bishop of Spoleto, and soon reached a position of importance, receiving endowments from the Lombard and Carolingian rulers and from the popes. The monks were driven out by the Saracen invaders in the closing years of the ninth century, and it lay desolate for fifty years. ”
