pertain to Three principal Members, which are
_Pillars_, _Piedements_, _Chambranles_; the _Pillars_ taken Generically,
and as opposite to _Piedements_, and _Chambranles_ or _Door-Cases_, have
Three parts, _viz._ The _Pedestal_, the _Pillar_, and the _Ornaments_.
Every one of these Parts is likewise divided into Three other Parts, for
the _Pedestal_ is composed of the _Basis_, its _Die_ and its _Cornish_;
the _Pillar_ Comprehends its _Base_, _Shaft_ and _Capital_. The
_Ornaments_ consist in the _Architrave_, _Frise_, and _Corniche_.

The _Piedement_ or _Fronton_, has likewise Three Parts, _viz._ The
_Tympan_, the _Corniches_, and the _Acroteres_. The _Chambranle_ or
_Door-Case_ is composed of two _Pieds-droits_, or _Piers_, and the
_Lintel_ which also supports a _Frise_, which has likewise its
_Cornich_.

The Disposition, Form, and different Proportions of all the Parts make
two things, to which all that is Beautiful in Building hath a Relation,
which is _Gender_ and _Order_.

_Gender_ depends of the Proportion, which is between the thickness of
the _Pillars_ and the space betwixt them.

_Order_, doth likewise depend in part upon the Proportion which is
between the thickness of the _Pillars_, and their height; but we must
likewise joyn to this Proportion many other things that appertain to the
principal Parts of the _Pillars_, and other Parts which accompany it,
such as are the _Gates_, the _Chambranles_, or _Door-Cases_; and other
things which are different in different _Orders_.

_Of the Five sorts of Fabricks_.

There are Five sorts of Fabricks; The First is called _Pycnostyle_, viz.
where the Pillars are very close one to another, in such a Proportion
that there is but from one Pillar to another, the space of a Diameter
and half of the Pillar. See the _Fig._ AA. _Tab._ 2.

The Second is called _Systile_, viz. where the Pillars seem to be joyned
together, are notwithstanding a little more distant one from another
than in the _Pycnostile_; for the intercolumniation is two Diameters of
the Pillars.

[Sidenote: _Lib. 2. Chap. 3._]

The Defect that is observ'd in the _Systile_ as well as in the
_Pycnostile_ is, that the Entrance of the Fabricks which are placed in
that distance are very narrow: So that _Vitruvius_ remarks that the
Ladies as they walk to the Temple hand in hand, were forced when they
came thither to quit one another, because they could not go two a Breast
between the Pillars. See t
