Issuing from this palace we may descend to the Ponte Sisto, the ancient Janiculensis, but the present edifice is I believe entirely modern. On the other side is the fountain of this name. The water guggles from a hole in a wall forming the back of an arched recess, into a vase just below, over the edges of which it runs, and falls into the basin at bottom. The architecture is not bad, but the principal fall ought to have been first. A few steps farther on, is the Church of the Santissima Trinità, famous for a picture of the Trinity by Guido. If the head of the Deity had been intended for that of Moses, it would be universally acknowledged sublime, but the attempt to represent this subject, must always produce disappointment or disgust. Near this is the Monte di Pietà, a public establishment for lending money on pledges, and resembling perhaps in some degree our savings banks. We return again over the bridge, and ascending by the mills supplied from the Fontana Paolina, go to the botanic garden, which contains but few plants.[3] It occupies a situation just above the fountain, which indeed pours forth a river. There are three equal arches discharging as many equal streams of water, and two smaller ones, with only a spout in each. An enormous attic rises above these arches, to receive the inscription, and the whole is crowned with a sort of pediment ornament, much like that at the Fontana Felice, somewhat larger, and considerably worse. The whole merit of the thing consists in the great abundance of water; but it is said not to be good. I do not know precisely whether it is brought from the lake of Bracciano, or from springs in that neighbourhood. It is clear and bright, and supplies fountains and turns mills, to which purpose it is almost exclusively applied, as well as any water could do. A short walk conducts us to the Church of San Pietro in Montorio, rising on an advancing point of the Janiculum, and commanding a glorious view, including almost all the objects of antiquity in Rome which can possibly be comprised in any general view; and nearly all the modern city, with its domes and palaces; the Tiber; the seven hills, or rather six, for the eye cannot hence distinguish the Viminal, three of which are covered with gardens and vineyards; Monte Testaccio; great part of the walls, and the country beyond them; Monte Albano; and the Apennines. The church itself has two orders in front, each presenting a single pilaster at each angle of the building. The lower includes a large and handsome doorway, the upper a single circular window. The simplicity of this disposition renders it superior to most of the church fronts in Rome. It was built about 1500, at the expense of Isabella of Spain, wife of Ferdinand the Fourth.
