1Columns, over which ran an Architrave, Freze
and
Cornice, according to the Rules juſt now
laid
down for Porticoes; and the reſt of the
Void
above the Cornice was left quite open
for
ſetting of Statues or large Candleſticks.
Others incloſed the Entrance into ſuch Chapels
with
a Walls brought half Way on each Side.
Thoſe who imagine that the great Thickneſs
of
the Walls adds Dignity to a Temple, are
greatly
miſtaken; for who is there that does
not
diſlike a Body compoſed of gouty Limbs?
beſides that when the Walls are too thick, they
always
intercept the Light.
In the Rotonda at
Rome, the excellent Architect who had the
Care
of that great Work having in it Occaſion
for
thick Walls, built the Ribs entirely of ſolid
Work
, without any Stuffing, and thoſe Inter­
ſpaces
which a leſs skilful Artiſt would have
ſtuffed
, he employed in Niches and other
pertures
, whereby he ſaved Expence, and made
the
Structure leſs heavy, and more beautiful.
The Thickneſs of the Walls muſt be proporti­
oned
after the Manner of Columns; that is to
ſay
, their Thickneſs muſt correſpond to their
Height
, as in thoſe.
I have obſerved that the
Ancients
, in building their Temples, uſed to
divide
the Front of their Platform into twelve
Parts
; or, when they would make them parti­
cularly
ſtrong, into nine, and one of thoſe
Parts
was the Thickneſs of the Wall.
In cir­
cular
Temples the Wall was never leſs high
than
half the Diameter of its inner Area;
many
made it two Thirds of that Diameter,
and
ſome three Fourths, which was the Height
to
which they carried the Wall before they be­
gan
the Sweep of the Cupola.
But the more
diſcreet
Workmen divided the Circumference
of
this circular Platform into four Parts; and
one
of thoſe fourth Parts being extended to a
Line
was equal to the inward Height of the
Wall
, which is as four to eleven: And this
Practice
has been alſo imitated in ſquare Tem­
ples
as well as round ones, and in many other
Kinds
of Structures that were to be covered
with
Arches.
But where there were to be
Chapels
on each Side in the Wall, to make the
Aperture
ſeem the Larger they ſometimes raiſed
their
Wall equal in Height to the whole Breadth
of
the Area.
In round Temples the inward
Height
of the Wall will not be the ſame as the
outward
: Becauſe within the Wall ends exact­
ly
where the Sweep of the Arch begins; but
without
, it is carried up ſtraight to the Top of
the
Cornice.
If the Cupola have a Cover on
the
Outſide made with Degrees like Steps, the
outward
Wall will take up a third Part of it;
but
if the Cover be made with ſtraight Lines
and
a common Slope, then the outward Wall
will
take up half.
Nothing is more conveni­
ent
for building the Walls of a Temple, than
Brick
; but then it muſt be caſed with ſome­
thing
handſomer.
There have been many dif­
ferent
Opinions with Relation to the Adorning
of
the Walls of Temples.
At Cyzicus a Town
in
Bythinia there was a Temple which had its
Walls
adorned with a very beautiful Stone, and all
the
Joints pointed with maſſy Gold.
In the Tem­
ple
of Minerva at Elis, the Brother of Phidias,
the
celebrated Carver, made an Incruſtation of
Stuc
tempered with Saffron and Milk.
The
Kings
of Ægypt encompaſſed the Monument
of
Simandes, which was the Scpulchre for the
Concubines
of Jupiter, with a Circle of Gold
no
leſs than a Cubit or Foot and half broad,
and
three hundred ſixty-five Cubits round,
with
a Day of the Year inſcribed upon every
Cubit
.
Others condemned this Exceſs of Or­
nament
in Temples. Cicero, being guided by
Plato's Opinion, thought it neceſſary that the
People
ſhould be admoniſhed by the Laws to
lay
aſide all Manner of Delicacy in the Adorn­
ing
their Temples, and take Care only to have
them
perfectly clean and white.
However,
ſays
he, let the Structure of them be beautiful.
I confeſs, for my own Part, I am very ready to
believe
, that Purity and Simplicity of Colour,
as
of Life, muſt be moſt pleaſing to the Divine
Being
; and that it is not proper to have any
Thing
in a Church that may be likely to draw
off
Men's Thoughts from Devotion and fix
them
upon the Pleaſure and Delight of the
Senſes
: But ſtill I am of Opinion, that he is
highly
to be commended, who, as in other
publick
Structures, ſo alſo in Temples, without
departing
from the Gravity requiſite in ſuch
Works
, endeavours to have all the Parts, the
Walls
, Roof, and Pavement, as handſome and
clegant
as poſſible, ſtill chiefly having it in his
Eye
to make all his Ornaments the moſt dura­
ble
that may be.
Thus nothing can be more
proper
for the Ornament of the Roof on the
Inſide
than all Sorts of Moſaic Work made of
Marble
, Glaſs, and other laſting Materials.
Stuc-work with Figures, according to the Prac­
tice
of the Ancients, may be a very handſome
Coat
for the Outſide.
In both you muſt take
the
greateſt Care to chuſe proper Places as
well
for your Pictures as Figures.
The Por­
tico
, for Inſtance, is the fitteſt Place for the
Repreſentation
of great Actions in Pictures.
