of marble, jetting out waters; in the midst of these stands a Janus quadrifrons, that cast forth four girandolas, called from the resemblance (to a particular exhibition in fireworks so named) the Fontana di Spéccho (looking-glass). Near this is a place for tilting. Before the ascent of the Palace is the famous fountain of Leda, and not far from that, four sweet and delicious gardens. Descending thence are two pyramids of water, and in a grove of trees near it the fountains of Tethys, Esculapius, Arethusa, Pandora, Pomona, and Flora; then the prancing Pegasus, Bacchus, the Grot of Venus, the two Colosses of Melicerta and Sibylla Tiburtina, all of exquisite marble, copper, and other suitable adornments. The Cupids pouring out water are especially most rare, and the urns on which are placed the ten nymphs. The grots are richly paved with pietra-commessa, shells, coral, &c.

Towards Roma Triumphans, leads a long and spacious walk, full of fountains, under which is historised the whole Ovidian Metamorphosis, in rarely sculptured mezzo relievo. At the end of this, next the wall, is the city of Rome as it was in its beauty, of small models, representing that city, with its amphitheatres; naumachi, thermæ, temples, arches, aqueducts, streets, and other magnificences, with a little stream running through it for the Tiber, gushing out of an urn next the statue of the river. In another garden, is a noble aviary, the birds artificial, and singing till an owl appears, on which they suddenly change their notes. Near this is the fountain of dragons, casting out large streams of water with great noise. In another grotto, called Grotto di Natura, is an hydraulic organ; and, below this, are divers stews and fish-ponds, in one of which is the statue of Neptune in his chariot on a sea-horse, in another a Triton; and, lastly, a garden of simples. There are besides in the palace many rare statues and pictures, bedsteads richly inlaid, and sundry other precious moveables: the whole is said to have cost the best part of a million.

Having gratified our curiosity with these artificial miracles, and dined, we went to see the so famous natural precipice and cascade of the river Anio, rushing down from the mountains of Tivoli with that fury that, what with the mist it perpetually casts up by the breaking of the water against
