THE HOUSE OF AUGUSTUS (18).

"He resided in a small house formerly belonging to Hortensius. This was destroyed by fire, and rebuilt by contributions of the public" (Suetonius). The palace was destroyed by fire, under Titus, A.D. 72; the ruins were filled in by Domitian in the second year of his reign, and upon the top he built his celebrated palace. The remains of the Palace of Augustus—not now accessible, being under the convent—were explored and partly excavated some years ago.

From the Palace of Domitian (17) we can descend into some of the small chambers, the vault of one being adorned with a fresco representing Victory.

THE GELOTIANA (32),

mentioned by Suetonius as the place from which Caligula viewed the games in the Circus Maximus, is supposed to have been a house occupied by the guard and servants of the palace. Its ruin consists of chambers at the base of the hill, under the convent. It was here that the skit of the Crucifixion, now in the Museum of the Collegio Romano, was found. (See [page 160] .) The walls are still covered with names, &c., scratched by the soldiers.

THE HOUSE OF TIBERIUS (3).

We learn from Suetonius and Tacitus that it was situated on the western side of the Palatine, overlooking and communicating with the Velabrum. The remains consist of vast halls and substructions, and a row of arches supposed to have been the guard's quarters. This palace has yet to be excavated.

THE PALACE OF CALIGULA AND HADRIAN (2).

"Having continued part of the Palatine as far as the Forum, he converted the Temple of Castor and Pollux into the vestibule of his house." "He built a bridge over the temple of the deified Augustus, by which he joined the Palatine to the Capitol" (Suetonius). He connected his palace with that of Tiberius by means of porticoes. The remains consist of a suite of rooms, portions built over the Clivus Victoriæ, chambers with fresco and stucco decorations, and mosaic pavements, also a portion of the beautiful marble balustrade of the solarium. Suetonius tells us that this palace was destroyed by fire; in fact, most of the remains show the construction of Hadrian, who must have rebuilt it and used it as his palace.

The remains of this palace have been recently uncovered at the northern side of the Palatine. It appears that the palace was built in a series of terraces against the Palatine Hill, the construction showing work of Caligula, Trajan, and Septimius Severus. There are some chambers which were warmed with hot air in terra-cotta pipes, and containing fragments of statuary on the lowest level excavated. Then, on the terrace above, there is an arcade paved with blocks of silex, and on one side shops. A flight of travertine steps conducts to some small chambers above, with mosaic pavements and frescoes, which were built by Hadrian against a wall of Caligula having frescoes on yellow and white grounds. The side walls and vaults are decorated with frescoes of the time of Hadrian.
