The second great reconstruction of the stage-buildings took place in the reign of Nero, after a lapse of perhaps two hundred years. The whole of this part of the theatre was then adapted to the Roman fashion. An elaborate architectural façade, consisting of columns and entablatures, was erected at the back of the stage, the old Lycurgean wall _n_ being used as a foundation. A portion of the frieze from this façade is still in existence, and contains the dedication to Nero which has already been referred to.[388] Two of the columns are also preserved in part. Behind the columns and frieze a wall was erected, according to the Roman custom; and at the same time new side-wings were built, slightly diminishing the length of the whole structure. The foundations of these erections are marked _p_ in the plan. In Roman theatres, as we have seen, the stage projected much further forward than in the Greek. It was also reduced in height to five feet, so that the spectators in the orchestra might be able to see over the top. A stage of this type was doubtless erected in the Athenian theatre at the time of these reconstructions, though it has now entirely disappeared. But part of it seems to have been used for the existing stage, that of Phaedrus, by which it was replaced in the third century A.D. This stage, which is four feet three inches high, is adorned in front with a bas-relief. The bas-relief has obviously been constructed out of old materials, and has been much cut about, and curtailed several inches in height, before being placed in its present situation. It seems clear that it was intended originally for the Neronian stage, which must therefore have been about five feet high. The position of the front-wall in the Neronian stage cannot be determined from the ruins, but was probably much the same as in the stage of Phaedrus (_h-h_). One peculiarity of the Neronian reconstruction is the fact that the old Greek side-wings, with their rows of columns, were allowed to remain. But how they harmonized with the new Roman wings and columns it is difficult to conjecture.[389]
