The work of Gregory in Rome, however, was not confined to liturgy and discipline. The tradition of parasitism at Rome was not dead, and, as there was now no _Præfectus Annonæ_ to distribute corn to the citizens, it fell to the Church to feed them; and the Romans were now augmented by destitute refugees from all parts. Gregory had to find food and clothing for masses of people, to make constant grants to their churches and to the monasteries, to meet a periodical famine, and to render what miserable aid the ignorance of the time afforded during the periodical pestilence. Occasionally he had even to control the movements of troops and the dispatch of supplies; at least, in his impatience of the apparent helplessness of the imperial government and his determination to hold Catholic towns against the Lombards, he undertook these and other secular functions. The control of the vast Papal income and expenditure might alone have sufficed to employ a vigorous man. In Sicily, there were immense estates belonging to the Papacy, and other "patrimonies," as they were called, were scattered over Italy and the islands, or lay as far away as Gaul, Dalmatia, Africa, and the East. Clerical agents usually managed these estates, but we find Gregory talking about their mules and mares and cornfields, and the wages and grievances of their slaves and serfs, as familiarly as if he had visited each of them. It has been estimated, rather precariously, that the Papacy already owned from 1400 to 1800 square miles of land, and drew from it an annual income of from £300,000 to £400,000. Not a domestic squabble seems to have happened in this enormous field but Gregory intervened, and his rigid sense of justice and general shrewdness of decision command respect. Then, there was the equally heavy task of distributing the income, for the episcopal establishment cost little, and nothing was hoarded. In sums of ten, twenty, or fifty gold pieces, in bales of clothing and galleys of corn, in altar-vessels and the ransom of captives, the stream percolated yearly throughout the Christian world, as far as the villages of Syria. Monks and nuns were especially favoured.
