The honour of being the native place of the gens Julia gave it some artificial importance in the imperial times. Tiberius is mentioned by Tacitus as erecting a sacrarium of the Julian family and a statue of Augustus there, and founding Circensian games in honour of the gens Julia. Some inscriptions found on the spot show the town still existed in the 2nd century A.D. It is now occupied by plots of land laid out as gardens. The Villa of Clodius, Cicero’s enemy, appears to have been at or near the thirteenth milestone from Rome, close to the left side of the Appian Road, between Bovillæ and the modern Albano. It was raised on immense substructions, the arches of which were capable of concealing a thousand men, and Cicero declares that Clodius had not respected even the confines of the Temple of Jupiter Latiaris or the sacred groves of Alba.[136] The ruins which lie under Castel Gandolfo, on the left side of the road towards the Porta Romana of Albano, may have formed part of the substruction of which Cicero speaks. The estate of Clodius passed after his death, when the family of the Claudii Pulcri became extinct, into the hands of the Claudii Nerones, from whom Tiberius inherited it, and thus it became imperial property. [Sidenote: Villa of Pompey.] The Villa of Pompey was between that of Clodius and Aricia, and therefore occupied the site of the present town of Albano. Nibby thinks that the walls of reticulated work in the Villa Doria belonged to Pompey’s house, and that the great tomb, near the Roman gate of Albano was Pompey’s burial place. Plutarch states that Pompey was buried at his Alban villa. The tomb, with five truncated cones, usually called the Tomb of the Horatii and Curiatii, has also been called the Tomb of Pompey. It is more probably an imitation of the old Etruscan tombs executed at a later time. After the death of that great general, the estate became the property of Dolabella, and subsequently of Antony, who held it till the battle of Actium, when Augustus took possession of it. After the adoption of Tiberius, it was united with the Clodian grounds, and thus formed the nucleus of the Albanum Cæsarum. [Sidenote: Albanum Cæsarum.] Augustus and some of the early emperors found the Albanum a convenient halting-place on their journeys to the south, but it was in the time of Domitian that the place was extended so much as to contain a military camp, enormous reservoirs of water, thermæ, a theatre, an amphitheatre, and a circular temple. It is called Arx Albana by Juvenal, Tacitus and Martial.
