iedement_ must be equal to that below, excepting the last great
_Cymatium_, which ought not to be upon the _Cornice_ below the
_Piedement_, but it ought to go over the _Cornices_ which are sloping
upon the _Piedement_ or _Fronton_.

This great _Cymatium_ ought to have of height an 8th part more than the
_Crown_, or _Drip_, or _Larmier_.

In places where there are no _Piedements_, in the great _Cymatiums_ of
the _Cornices_, must be cut the Heads of Lions, at such a distance, that
there must be one directly upon every Pillar, and that the other answer
directly upon the great _Dalles_, that cover the House. These Heads of
Lions are pierced through to convey the Water which falls from the Roof
upon the _Cornice_: The Heads of the Lions which are not directly upon
the Pillars, ought not to be pierced, to the end the Water may flow with
the greater impetuosity through those which are directly upon the
Pillars, and that it may not fall between the Pillars upon those who are
to go into the _Portico's_.

The _Greeks_ in their great Buildings never put any _Dentels_ under the
_Modillons_, because the _Rafters_ could not be under the _Forces_, or
_Sheers_, and it is a great fault that That, which according to the true
Rules of Building ought to be placed above, should be placed under in
the Representation.

For this Reason, the Ancients never approved of _Modillons_ in the
_Piedements_, nor of _Dentels_, but only simple _Cornices_; for neither
the _Forces_, _Sheers_, nor the _Rafters_ can be represented in the
_Piedements_, out of which they cannot jet but only directly out of the
Eaves of the House upon which they lie sloping.

The _Acroteres_ are three _Pedestals_, which are upon the Corners and
Middle of the _Piedement_ to support Statues; those of the Corner ought
to be as high as the Middle of the _Tympan_; but the _Acrotere_ in the
middle ought to be higher by an 8th part than the other.

All the Members or Parts which shall be placed upon the Capitals of
Pillars, _viz. Architraves_, _Frises_, _Cornices_, _Tympans_, and
_Acroteres_, should encline forward the 12th part of their height.

There is likewise another General Rule; which is, that all the parts
that jet out, should have their Projecture equal to their Height.

_Of the_ Thuscan _Order._

It hath been said that all Buildings have three Parts, which may be
different according to the divers Order, _viz._ The _Pillars_, the
_Piedements_, and the
