The Pillars were as high as the Isles or Wings were broad, and these Isles or Wings had a third part of the great Vault in the middle. There was likewise a Second rank of Pillars upon the Wings, which made high Galleries, and these Second rank of Pillars were placed upon a _Pedestal_ in the form of a Partition, high enough to hinder those that were in the high Galleries from being seen by those that were below. At the End of every _Basilica_, there was a high and great Hall called _Chalcidiques_, which were joyned one to another by high Galleries: they served the Spectators while Justice was distributed. The _Theaters_ were composed of three parts, _viz._ The Steps or Degrees, which were instead of Seats for the Spectators: they were disposed in a Semi-circle, and they closed a void space in the middle and at the bottom of the whole _Theater_, which was called the _Orchestra_. [Sidenote: _Lib. 5. Chap. 6._] The _Orchestra_ was made in the _Graecian Theatre_, to Dance the Ballets. The Senators were placed in that of the _Romans_, because the Ballets were Danced upon the Scene. [Sidenote: _Lib. 5. Chap. 6._] [Sidenote: _Lib. 5. Chap. 6._] Above and quite round the Steps or Degrees was a _Portico_ of Pillars, the Steps being separated by divers _Palliers_ or Landing and Resting places which went round, and by streight passages which went ascending from one _Palliere_ or Landing place to another; so that the ways which led from the second _Palliere_ to the third, parted betwixt those of the first, and ended betwixt those of the third. The Steps or Degrees were 14 or 15 Inches high, and from 28 to 30 broad. Under the Degrees, above every _Palliere_, there were in the great _Theaters_ 13 _Chambers_, in which were Vessels of Brass, set to several Tunes, or Tones; which by their Echo augmented the Voice of the Players. The Scene or Stage, was composed of the _Pulpit_, the _Proscenium_ and the _Parascenium_. The _Pulpit_ was the place where the Actors played: it was raised not above five Foot at the most above the _Orchestra_, or _Pit_. The _Proscenium_ was the Front of the Stage, which was adorned with Pillars of several sorts one above another. These Orders were so proportioned, that the second was a fourth part lesser than the first. The third diminishing according to the same Proportion. The Front had three Gates, that in the middle which was the greatest was called the _Royal Gate_, the two others were called the _Gates of Strangers_. [Sidenote: _Lib. 5._] These three Gates were closed with Machines, made in a Triangle, and composed of three Fronts or Faces well Painted, to represent Buildings in Perspective; they served for the changing of the Scenes, when these Machines were turned. And the Paintings represented three sorts of Buildings, which made three sorts of Scenes, _viz._ The _Tragick_ by _Magnificent Pallaces_, the _Comick_ by _Private Houses_, the _Satyrical_ (_i. e._ the _Pastoral_) by _Fields_ and _Groves_.
