The Aventine continued to be inhabited, and even populous, until the sixth century, from which period its prosperity began to decline. In the eleventh century it was occupied by the camp of Henry IV. of Germany, when he came in war against Gregory VII. In the thirteenth century Honorius III. made a final effort to re-establish its popularity; but with each succeeding generation it has become--partly owing to the ravages of malaria--more and more deserted, till now its sole inhabitants are monks, and the few ague-stricken contadini who look after the monastic vineyards. In wandering along its desolate lanes, hemmed in by hedges of elder, or by walls covered with parasitical plants, it is difficult to realize the time when it was so thickly populated; and except in the quantities of coloured marbles with which its fields and vineyards are strewn, there is nothing to remind one of the 16 ædiculæ, 64 baths, 25 granaries, 88 fountains, 130 of the larger houses called _domus_, and 2487 of the poorer houses called _insulæ_, which occupied this site. The present interest of the hill is almost wholly ecclesiastical, and centres around the story of St. Dominic, and the legends of the saints and martyrs connected with its different churches. * * * * * The best approach to the Aventine is behind the Church of Sta. Maria in Cosmedin, where the _Via Sta. Sabina_, once the Clivus Publicius (available for carriages), turns up the hill. A lane on the left leads to the Jewish burial-ground, used as a place of sepulture for the Ghetto for many centuries. A curious instance of the cupidity attributed to the Jewish race may be seen in the fact, that they have, for a remuneration of four baiocchi, habitually given leave to their neighbours to discharge the contents of a rubbish cart into their cemetery, a permission of which the Romans have so abundantly availed themselves, that the level of the soil has been raised by many yards, and whole sets of older monuments have been completely swallowed up, and new ones erected over their heads.
