The auditorium, unlike the rest of the building, was subjected to very little alteration in later times. The parts of it which are still preserved remain in much the same state as in the age of Lycurgus. The various successive changes in the style of the dramatic performances, while they led to corresponding changes in the orchestra and the stage-buildings, had naturally no effect upon the structure of the auditorium. A few innovations were introduced in the Roman period, mostly for the purpose of increasing the comfort of the more distinguished spectators. We have seen that in the old theatre the only person provided with a canopy was the priest of Dionysus. The same luxury was now extended to all the people in the front benches. An awning was erected on wooden posts to protect them from the sun. Three lines of holes for the reception of the posts may still be traced in the stone-work, one in front of the thrones, one behind, and one in the second row of ordinary seats. It seems that about this date there was an increase in the number of people for whom seats of honour were required. The front row of the ordinary benches was removed, in the way already described, to supply the necessary space. Single marble thrones were also set up here and there in the rows further back. Another change, which involved some disfigurement of the building, was made about the same time. A large stone basis, approached by steps, was erected in front of the sixth vertical passage, thus closing the approach to that passage, and also necessitating the removal of four of the marble thrones, which were placed elsewhere. The basis was probably intended as a sort of royal box, and held a special throne reserved for people of imperial rank. A similar basis was also erected, probably for the same purpose, behind the seat of the priest of Dionysus. § 5. _The Orchestra._
