Thus have we made the tour of the Seven Hills, commencing at the Aventine on the extreme right, and proceeding in a semicircular line over the low swellings which lie in their peaceful covering of flower and weed, onward to the Quirinal, which rises, with its glittering casements, on the extreme left. They hold in their arms, as it were, modern Rome, with the Tiber, like a golden belt, tying in the city, and bounding the Campus Martius, on which it is seated. On the west of the Tiber are other two hills, which, though not of the seven, are worth mentioning. The first is the JANICULUM, with the _Trastevere_ at its base. The inhabitants of this district pride themselves on their pure Roman blood, and look down upon the rest of the inhabitants as a mixed race; and certainly, if ferocious looks and continual frays can make good their claim, they must be held as a colony of the olden time, which, nestling in this nook of Rome, have escaped the intermixtures and revolutions of eighteen centuries. It has been remarked that there is a striking resemblance between their faces and those of the ancient Romans, as graven on the arch of Titus. They are the nearest neighbours of the Pope, whose own hill, the VATICAN, rises a little to the north of them. On the Vatican mount stood anciently the circus of Nero; and here many of the early Christians, amid unutterable torments, yielded up their lives. On the spot where they died have arisen the church of St Peter and the palace of the Vatican,--now but another name for whatever is formidable to the liberties of the world.
