time were monasteries, generally surrounded by strong walls, capable of affording protection to a powerful community, and in which the humble and poor could find refuge in time of trouble. These establishments, and the mediæval fortresses and towers built into the midst of the ruins, occupied with many wild spaces between, where the luxuriant herbage buried fallen pillars and broken foundations, the wastes of desolation which filled up half the area of the town. The population seems to have clustered about the eastern end of the city; all the life of which one reads, except an occasional tumult around St. Peter's and north of St. Angelo, seems to have passed on the slopes or under the shadow of the Aventine and Coelian hills, from thence to the Latin gate, and the Pope's palace there, the centre of government and state--and on the hill of the Capitol, where still the people gathered when there was a motive for a popular assembly. The ordinary populace must have swarmed in whatsoever half-ruined barracks of old palaces, or squalid huts of new erection hanging on to their skirts, might be attainable in these quarters, clustering together for warmth and safety, while the rest of the city lay waste, sprinkled with ruins and desolate paths, with great houses here and there in which the strangely mixed race bearing the names, often self-appropriated, of ancient Roman patrician families, lived and robbed and made petty war, and besieged each other within their strong walls. One of these fortified houses or towers, built at or on the bridge of St. Angelo--in which the noble owner sat like a spider, drawing in flies to his web, taking toll of every stranger who entered Rome by that way--belonged to a certain Cencio[3] or Cencius of the family of Tusculum, the son of the Præfect of Rome. The Præfect, unlike his family, was one of the most devoted adherents of the Popes; he is, indeed, in the curious glimpse afforded to us by history, one of the most singular figures that occur in that crowded foreground. A mediæval noble and high official, he was at the same time a lay-preacher, delighted to exercise his gift when the more legitimate sermon failed from any cause, and only too proud, it would appear, of hearing his own voice in the pulpit. That his son should be of a very different disposition was perhaps not to be wondered at. Cencius was as turbulent as his father was pious; but he must have been a soldier of some note, as he held the post of Captain of St. Angelo, and in that capacity had maintained during a long siege the anti-pope Cadalous, or Honorius II., from whom, brigand as he was, he exacted a heavy ransom before permitting the unfortunate and too ambitious prelate to steal away like a thief in the night when his chance was evidently over. Cencius would seem to have lost his post in St. Angelo, but he maintained his robber's tower on the other end of the bridge, and was one of the most dangerous and turbulent of these internal enemies of Rome.
