5The scamilli being prepared and set, the bases of the columns may be laid, their height being equal to the semidiameter of the column including the plinth, and their projection, which the Greeks call ἔκφορα, one quarter of the diameter of the column. Thus the height and breadth, added together, will amount to one diameter and a half.
5This finished, let the bases of the columns be set in place, and constructed in such proportions that their height, including the plinth, may be half the thickness of a column, and their projection (called in Greek ἑκφορἁ) the same. Thus in both length and breadth it will be one and one half thicknesses of a column.
