denticulus is introduced, and its depth is made proportionate 
to the height of the epistylium. 
It has been generally supposed that Vitruvius meant 
to include the cymatium in the height he assigns to the 
epistylium; but whenever he intends to include in one 
proportion the height of two members together, he expressly 
marks his intention. Thus speaking of the epistylium of 
Doric columns and the taenia, which is in the Doric order 
what the cymatium is in the lonic, he says, * Epistylii 
altitudo unius moduli cum taenia et guttis;' and in Book il. 
Chapter 3, “ Corona cum suo cymatio quantum media fascia 
epistylii." 
The height of the columns being more than twenty feet, 
it is to be divided into twelve parts and a half; one of these 
is given to the height of the epistylium; which therefore 
will be 1.9.128; this added to one seventh part of it gives 
2.0.146, for the height of the epistylium and cymatium 
together. The corresponding height in the temple of 
Erectheus is 2.1.05. The zophorus of this temple having 
been ornamented with bronze sculpture, let us give to the 
zophorus of the Vitruvian entablature the proportion it 
requires when ornamented in a similar manner. In this 
case, the epistylium being 1.9.128, the zophorus will be 
2.2.41, which added to one seventh part of it for the 
cymatium, gives 2.6.18 for the zophorus and cymatium 
together. The zophorus in the Erectheum is 1.11.75, 
which together with 5.08, the proportionate height of the 
cymâtium below the denticulus, gives 2.4.83: thus those
