The four years that elapsed between his return to his convent and his election to the Popedom (or to speak more justly the bishopric of Rome) were years of trouble. In addition to the constant danger of invasion, the misery, even when that was escaped, of the tales brought to Rome by the fugitives who took refuge there from all the surrounding country, in every aggravation of poverty and wretchedness, and the efforts that had to be made for their succour--a great inundation of the Tiber, familiar yet terrible disaster from which Rome has not even now been able to secure herself, took place towards the end of the period, followed by a terrible pestilence, its natural result. Gregory was expounding the prophet Ezekiel in one of the Roman churches at the time of this visitation: but as the plague increased his sorrowful soul could not bear any bondage of words or thoughts apart from the awful needs of the moment, and closing the book, he poured forth his heart to the awed and trembling people, exhorting all to repent, and to fling themselves upon God's mercy that the pestilence might be stayed. In all such terrible emergencies it is the impulse of human nature to take refuge in something that can be done, and the impulse is no doubt itself of use to relieve the crushing weight of despair, whatever may be the form it takes.

PAUL.] We clean and scrub and whitewash in our day, and believe in these ways of arresting the demons; but in old Rome the call for help was more impressive at least, and probably braced the souls of the sufferers as even whitewash could not do. The manner in which Gregory essayed to turn the terrible tide was by a direct appeal to Heaven. He organised a great simultaneous procession from all the quarters of Rome to meet at "the Church of the Virgin"--we are not informed which--in one great united outcry to God for mercy. The septiform litany, as it was called, was chanted through the desolate streets by gradually approaching lines, the men married and unmarried, the priests and monks each approaching in a separate band; while proceeding from other churches came the women in all their subdivisions, the wives, the widows, the maidens, the dedicated virgins, Ancillæ Dei, each line converging towards the centre, each followed no doubt from windows within which the dying lay with tears and echoes of prayers. Many great sights there have been in old Rome, but few could have been more melancholy or impressive than this. We hear of no miraculous picture, no saintly idol as in later ceremonials, but only the seven processions with their long-drawn monotones of penitence, the men by themselves, the women by themselves, the widows in their mourning, the veiled nuns, the younger generation, boys and girls, most precious of all. That Gregory should have had the gift to see, or believe that he saw, a shining angel upon
