column properly chamfered. In. respect of the addi-tional thickness in the middle thereof, as mentioned inthe third hook, respecting* Ionic columns, reference musthe made to that place. As the external symmetry ofCorinthian, Doric, and Ionic edifices has been explained,it is necessary to give directions for the interior arrange-ments of the cell and pronaos.

CHAPTER IV.

OF THE INTERIOR OF THE CELL AND THE ARRANGE-MENT OF THE PRONAOS.

The length of a temple must he twice its width. Thecell itself is to he in length one-fourth part more thanthe breadth, including the wall in which the doors areplaced. The remaining three parts run forward to theantse of the walls of the pronaos, which antse are to heof the same thickness as the columns. If the temple bebroader than twenty feet, two columns are interposedbetween the two antse, to separate the pteroma from thepronaos. The three intercolumniations between the antseand the columns may be enclosed with fence work, eitherof marble or of wood, so, however, that they have doorsin them for access to the pronaos. If the width be greaterthan forty feet, columns opposite to those which are be-tween the antse, are placed towards the inner part, of thesame height as those in front, but their thickness is to bediminished as follows. If those in front are an eighthpart of their height in thickness, these are to be oneninth; and if the former are a ninth, or a tenth, the lat-ter are to be proportionally diminished. For where theair does not play round them, the diminution thus madewill not be perceived; lest, however, they should appear
