The book of what we call ancient history was closed: the Middle Age was beginning. Gregory was peculiarly adapted to impress the world at this stage of transition. His father, Gordianus, had been a wealthy patrician, with large estates in Sicily and a fine mansion on the Cælian hill. De Rossi would make him a descendant of the great family of the Anicii, but the deduction is strained. Gregory's mother was a saint. He inherited vigour and administrative ability, and was reared in the most pious and most credulous spirit of the time. He was put to letters, and we are told that he excelled all others in every branch of culture. Let us say, from his works, that--probably using the writings of the Latin fathers as models--he learned to write a Latin which Jerome would almost have pronounced barbarous, but which people of the sixth century would think excellent, at times elegant. There was very little culture left in Rome in Gregory's days.[78] About the time when Gregory came into the world (540), Cassiodorus was quitting it to found a monastic community on his estate, and he had the happy idea of rescuing some elements of Roman culture from the deluge; though to him culture meant Donatus and Martianus Capella rather than the classics. He succeeded, too, in engaging the industry of the Benedictine monks, to some extent, in copying manuscripts. Culture was, happily, not suffered to die. In Rome, however, it sank very low, and, for centuries, the Latin of the Papal clerks or the Popes is generally atrocious. Gregory, in 573, was Prefect of Rome when it was beset by the Lombards. The desolation which ensued may have finally convinced him that the end of the world approached: a belief which occurs repeatedly in his letters and sermons. In the following year, he sold his possessions, built six monasteries in Sicily, converted his Roman mansion into the monastery of St. Andrew, and, after giving the rest of his fortune to the poor, began a life of stern asceticism and meditation on the Scriptures. One day he saw some Anglo-Saxon slaves in the market, and he set off to convert these fair, blue-eyed islanders to the faith. But Pope Benedict recalled him and found an outlet for his great energy in secretarial duties at the Lateran.
