pit_ 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_.

The _Parascenium_ or _Postscenium_ was the hinder part of the _Theater_,
and the place whither the Actors retired and dressed themselves, and had
their Rehearsals, and where the Machines were kept. Near the _Theaters_,
were Publick Walks, in length a _Stadium_, which is about 90 _Perches_.
There were Trees planted, and round about it were double _Porticos_,
which were every one as broad as the Pillars on the out-side were high;
for those within were higher by a fifth part, than those without, and
they were likewise of a different _Order_; for those without were of the
_Dorick Order_, and those within of the _Ionick_ or _Corinthian_.

[Sidenote: _Lib. 5. Chap. 13._]

The Ancients built their _Ports_ in two manners; at those which were
_Natural_, they only made _Portico's_ round about with _Magazines_ and
_Towers_ at the Ends, for to shut the _Port_ with a Chain.

Those which were _Artificial_, were built three several ways: The first
was to make Partitions of Wood only, without emptying the Water which
was within the Partitions, and they cast into the Partitions, Stone and
Mortar made with _Pozzolana_, thrown in hand over head; for they were
certain that this Mortar wou'd grow dry in the bottom of the Water. The
second Way was by making Partitions with ordinary Clay, or fat Earth at
the bottom of the Sea, after the Water had been emptied out by Pumps.
The third Way was to build a Mole upon the Sea-C
