"which draws its precious water from a source far beyond the walls, whence it flows hitherward through old subterranean aqueducts, and sparkles forth as pure as the virgin who first led Agrippa to its well-spring by her father's door. It is a great palace front, with niches and many bas-reliefs, out of which looks Agrippa's legendary virgin and several of the allegoric sisterhood; while at its base appears Neptune with his floundering steeds, and Tritons blowing their horns, and other artificial fantasies. At the foot of the palatial façade is strewn, with careful art and ordered irregularity, a broad and broken heap of massive rock. Over the central precipice the water falls in a semicircular cascade; and from a hundred crevices, on all sides, snowy jets gush up and streams spout out of the mouths and nostrils of stone monsters; while other rivulets that had run wild come leaping from one rude step to another, over stones that are mossy and ferns planted by nature. Finally, the water, tumbling, sparkling, and dashing, with never-ceasing murmur, pours itself into a great marble-brimmed reservoir. The tradition is, that by taking a parting draught, and throwing a sou in, the traveller will return to Rome, whatever obstacles seem to beset his path." Such is Hawthorne's description of this beautiful fountain. _Turn to the right_, Via Muratte, the first on the left, Via della Vergine, brings us into the Piazza SS. Apostoli. _On the right_ is the Balestra Palace, where Prince Charlie died in 1788. _On the left is_ THE CHURCH OF THE APOSTLES (SS. Apostoli). Several fragments are built into the portico, the most interesting of which is the bas-relief of the eagle which once decorated Cæsar's Forum. The church has been entirely redecorated, and is now reopened. In the course of the alterations, in 1873, the bodies of SS. Philip and James the Less were found enclosed in a marble sarcophagus. A new extensive crypt, decorated after the style of the catacombs, has been made to receive these remains. The heart of Maria Clementina Sobieski is preserved here. _Just beyond is_ THE COLONNA PALACE. _Open Tuesday, Thursday, Saturday, from 11 till 3. Entry, 17 Via Archi della Pilotta._ The pictures have the names of the artists on them.
