uld be double that of a single door;
if the door is to have four folds, its height should be increased.

6. Attic doorways are built with the same proportions as Doric. Besides,
there are fasciae running all round under the cymatia on the jambs, and
apportioned so as to be equal to three sevenths of a jamb, excluding the
cymatium. The doors are without lattice-work, are not double but have
folds in them, and open outward.

The laws which should govern the design of temples built in the Doric,
Ionic, and Corinthian styles, have now, so far as I could arrive at
them, been set forth according to what may be called the accepted
methods. I shall next speak of the arrangements in the Tuscan style,
showing how they should be treated.

CHAPTER VII

TUSCAN TEMPLES

1. The place where the temple is to be built having been divided on its
length into six parts, deduct one and let the rest be given to its
width. Then let the length be divided into two equal parts, of which let
the inner be reserved as space for the cellae, and the part next the
front left for the arrangement of the columns.

2. Next let the width be divided into ten parts. Of these, let three on
the right and three on the left be given to the smaller cellae, or to
the alae if there are to be alae, and the other four devoted to the
middle of the temple. Let the space in front of the cellae, in the
pronaos, be marked out for columns thus: the corner columns should be
placed opposite the antae on the line of the outside walls; the two
middle columns, set out on the line of the walls which are between the
antae and the middle of the temple; and through the middle, between the
antae and the front columns, a second row, arranged on the same lines.
Let the thickness of the columns at the bottom be one seventh of their
height, their height one third of the width of the temple, and the
diminution of a column at the top, one fourth of its thickness at the
bottom.

3. The height of their bases should be one half of that thickness. The
plinth of their bases should be circular, and in height one half the
height of the bases, the torus above it and conge being of the same
height as the plinth. The height of the capital is one half the
thickness of a column. The abacus has a width equivalent to the
thickness of the bottom of a colum
