meter of the Pillar; for as the
Proportion of an Edifice depends on the _Diameter_ of the
_Pillar_, so the greatness of the Modellians, their
number, and their space or distances, must have a just
Proportion or true Relation to the whole Fabrick.

_Module_ or _Model_ is a measure that is made use of to
regulate all the Proportion of the _Fabrick_: In the
_Dorick Order_ it's half the _Diameter_ of the Pillar; in
other Orders the Module is the whole _Diameter_.

_Monoptere_, from [Greek: monos] _solus_, and [Greek:
pteron] _ala_; is that which has but one Wing or Isle; it
was a sort of a round Temple, whose Roof was supported by
Pillars only.

_Mutuli_, from [Greek: mytilos], which signifies defect, as
being made thinner, and more abated above than below.
It's a sort of a Modellion in the Cornice of the _Dorick_

They made it with Ciment, which they put betwixt a Lay or

where the Players acted, and the Seats where the Spectators
sate. It was in this place where the Greek Comedians were
wont to dance.

_Order_, those Fabricks are said to be of different Orders,
when the Proportion which is between the thickness of the
_Pillars_ and their height, with all other things which are
required to this Proportion, are different.

_Ornaments_, _Vitruvius_ so calls the _Architrave_, _Frise_,
and _Cornice_.

_Oval_, vide _Echinus_.

P

_Parascenium_, from [Greek: para] and [Greek: skene]
_tentonum_, is the back part of the Theatre or Scene.

_Periptere_, from [Greek: peri] _circum_, and [Greek:
pteron] _ala_, which has a Wing round about. This was a sort
of a Temple, which had Pillars on all the four Parts, which
was different from the _Prostyle_, which had only Pillars
before, or In the _Front_, and from the _Amphiprostyle_,
