is seen here: A B is the half of the breadth of the Abacus, which is
regulated according to the breadth of the bottom of the Column, of which
one half is marked B 18; for the bottom of the Column being divided into
18, 19 are allowed to the Abacus: A C is the _Retreat_ which must be
made of the Corner A, of the Abacus inwardly, to draw the Line C D,
which must regulate the _Eye_ of the _Volute_ over which it must cross
as it passes. To make this _Retreat_ we must take one part and a half of
twelve, into which is divided the height or thickness, E F, of the whole
Capital, which height is equal to half the breadth of the Abacus. This
height, marked C D, is divided into nine parts and a half, of which one
and a half is given to the _Abacus_, and four and a half from the Abacus
to the middle of the _Eye_, which is traversed by the line G H; the
Figures 1, 2, 3, 4, mark the four Centers of the first four quarters of
the Volute; the four second quarters, and the four third (for the
Volutte has twelve) are taken in the Diagonal 1, 3, and 2, 4. H, I, is
the Astragal at the top of the Pillar which answers the _Eye_ of the
Volute. K K is the Egg or _Echinus_; L is the Axis of the Volutes; M M
is the ceinture of the lateral part of the Volutes. This relates to
_pag._ 103.

THE EXPLICATION Of the NINTH TABLE.

This contains the Proportions of the _Corinthian_ Capital, which makes
all the distinction betwixt _Jonick_ and the _Corinthian Order_, all
other Members, according to _Vitruvius_, being the same. A is the
_Corinthian_ Capital, which has for its height only the Diameter of the
bottom of the Column; B is the Capital of the Pantheon, which is higher
by a seventh part, _viz._ the thickness of the Abacus; C D is the height
of the Capital divided into seven, of which the Abacus has one, the
Voluta's and Foliages and Stalks two, the Foliage in the Range above
two, and that in the Range below two. To have the breadth of the Abacus,
we must give to its Diagonal E F the double of its height C D. To have
the greatness and just Proportion of its bending H, we must divide the
breadth of the Abacus E G into nine parts, and give it one.

At the bottom of this Table is represented the Herb _Branbursine_, which
grows round about the Basket, which is covered with a Tile, from which
_Vitruvius_ says the Sculptor _Callimachus_ took the first Model of the
_Corinthian_ Capital.
