I say, then, that the years of the beatific incarnation of the Son of God had reached the tale of one thousand three hundred and forty-eight, when in the illustrious city of Florence, the fairest of all the cities of Italy, there made its appearance that deadly pestilence, which, whether disseminated by the influence of the celestial bodies, or sent upon us mortals by God in His just wrath by way of retribution for our iniquities, had had its origin some years before in the East, whence, after destroying an innumerable multitude of living beings, it had propagated itself without respite from place to place, and so, calamitously, had spread into the West.

As consecrated ground there was not in extent sufficient to provide tombs for the vast multitude of corpses which day and night, and almost every hour, were brought in eager haste to the churches for interment, least of all, if ancient custom were to be observed and a separate resting-place assigned to each, they dug, for each graveyard, as soon as it was full, a huge trench, in which they laid the corpses as they arrived by hundreds at a time, piling them up as merchandise is stowed in the hold of a ship, tier upon tier, each covered with a little earth, until the trench would hold no more. But I spare to rehearse with minute particularity each of the woes that came upon our city, and say in brief, that, harsh as was the tenor of her fortunes, the surrounding country knew no mitigation; for there--not to speak of the castles, each, as it were, a little city in itself--in sequestered village, or on the open champaign, by the wayside, on the farm, in the homestead, the poor hapless husbandmen and their families, forlorn of physicians' care or servants' tendance, perished day and night alike, not as men, but rather as beasts.
