Nec solum id vitium in aedificiis, sed etiam in muneribus, quae a magistratibus foro gladiatorum scaenicisque ludorum dantur, quibus nec mora neque expectatio conceditur, sed necessitas finito tempore perficere cogit, id est sedes spectaculorum velorumque inductiones sunt et ea omnia, quae scaenicis moribus per machinationem ad spectationis populo conparantur.
And this defect is found not only in building, but also in the public spectacles which are given by magistrates; whether of gladiators in the forum, or of plays with a theatrical setting. In these neither delay nor expectation is permitted, but necessity compels the performance to take place within a fixed time. There is the seating for the shows, and there are the awnings to be drawn, and all those other things which, in accordance with theatrical tradition, are provided for popular spectacles by means of machinery.
