PLATE XXXV.
THIS Ionic example is taken from the Temple
of For tun a Vim lis, at Rome : which is usually-
supposed to be the most elegant instance of
this order.
PLATE XXXVI.
THE ionic VOLUTE.
AS this is the member which distinguishes the
Ionic order at first sight, we wish to impress it on
the memory of our readers: and the formation of it
being a curious piece of geometry, we have given
its principles, in the eye of the Volute at large, A.
To obtain this, first strike the surrounding circle:
within this, form a square (points upright) and pro-
long lines through these points to the extent re-
quired: the sweep from line to line will then in-
clude one quarter of a circle. Each side of the
square bisected, gives the points for an inner square,
and the place of one foot of the compasses to
strike the first spiral, for the first quarter of a
circle; beginning at 1, and sweeping the outermost
quarter of a circle; then moving the compasses to
2, for a second quarter, and so on to 3, and to 4..
The diagonal lines of the inner square divided into
third parts, give the points for striking the other
spirals; always going in a circular order, as 5, 6
7, 8, for the first, or outer, divisions of thirds; and
9, 10,
