Another portion of the Domus Aurea is still visible at the SETTE SALE, a large brick building lying in a vineyard to the left of the Via delle Sette Sale. The purpose of this was plainly to serve as a reservoir for water, and it is shown to have belonged to the Domus Aurea, and not to the Thermæ of Titus, by the correspondence of its position with the ground-plan of the former. It may have been afterwards used in connection with the Thermæ, and was possibly preserved with that view, while the rest of the palace was destroyed or buried. The peculiar construction of the interior, which is divided into nine compartments, communicating with each other by openings--not placed opposite to each other, but in a slanting direction across the building--is said to have been so arranged in order to prevent the heavy mass of water from bursting open the sides of the building. The group of the Laocöon was found near the Sette Sale, and it is supposed that the state-rooms of Titus may have contained that group of statues. [Sidenote: Thermæ or Baths of Titus.] Returning to the ruins of the Baths of Titus near the Coliseum it may be observed that these Thermæ were connected with the Coliseum by a portico, traces of which can still be seen on the north side of the amphitheatre. The arrangement of the building corresponded in some degree to that of the Baths of Caracalla, consisting apparently of a large square court surrounded by various offices and places for recreation, in the centre of which stood a vast mass of building containing the bath-rooms. The sides of this court were not parallel to any lines of building in the Domus Aurea, and, therefore, in order to form a level area many new substructions had to be erected. This is plainly the case with the theatre (A), which occupied the centre of the side towards the Coliseum. In order to raise this to the level of the rest of the area, the nine huge arched chambers, which are now a most conspicuous part of the ruins, were erected, and one of the courtyards of the Domus Aurea was filled, as we have seen, with parallel walls of brickwork. On each side of the theatre there were probably gymnasia, libraries, or ball courts (B B). The central building was occupied with the frigidarium and tepidarium, and the other usual adjuncts of a large Roman bath (C C C).
