The form of this temple was almost identical with that at Aricia. The interior of the cella was twenty-seven feet wide and forty-five feet long. It had columns of the Doric order in front and at the sides, but none at the back. The walls of the chamber at the back were here, as at Aricia, prolonged on each side, so as to close the side porticoes at the back. The surrounding area was about fifty-four feet in breadth at the sides, but in front a space of only eight feet was left open, in consequence of the position of the theatre, which abutted closely upon the temple. On the eastern side of the cella are traces of the rooms where the priests in charge of the temple lived. The shape of the forum can only be partially made out. From the plan published in the ‘Monumenti Gabinoborghesiani,’ it appears that it was a rectangular quadrilateral space, traversed by the Via Prænestina at the southern end, and that it was surrounded with a portico of Doric columns except at the end along which the Via Prænestina was carried. It was believed at the time when the excavations were made that the Curia and Augusteum could be distinguished among the surrounding buildings, but this seems now to be very doubtful. In the centre stood the statue of Titus Flavius Ælianus, the patron of the borough town. The pedestal of this statue with its inscription was found in situ in 1792. “The stone of Gabii quarried near the lake and the product of its extinct volcano, is used in many of the Roman buildings and especially in the building called the tabularium at the head of the Forum Romanum. It is a hard species of peperino, of a brownish-grey colour, which when exposed to the air becomes paler than the common peperino of Albano. It resists the action of fire, and is a compound of volcanic ashes mixed with small fragments of black, brown, and reddish lava, scales of mica, and bits of Apennine limestone.”[147] The city of Gabii lost its independence soon after the beginning of the Republican era of Rome. It was restored as a colony of veterans by Sylla, but sank into obscurity, and became almost proverbial for its desolate condition in the Augustan era. It afterwards recovered its prosperity in some degree by means of the celebrity of its cold baths, and in the time of Hadrian was patronised by the Emperor, who built an aqueduct and a Curia Ælia there. The inscriptions found on the spot belong chiefly to the Antonine era, and the busts of Severus and Geta also found there show that in the first part of the third century Gabii was still a flourishing borough town.
