making together a dimension nearly equal tocolumns.
The facade of this beautiful temple is dividedentablature, and the other two to the columnscolumns are 3 feet 4-85 inches in diameter, andintercolumniation is 5 feet S*95 inches, the next two each 5 feet 4 - 05 inches, and thosetowards the angles 4 feet 6-35 inches. The diameters taken together are 20 feet, and theintercolumniations 25 feet, so that the columns and their spaces are not in equal proportions:the former would have required a diameter of 3 feet 9 inches, which would have madethem nearly five diameters in height, instead of what they are; they would have been heavier,it is true, but more in accordance with the early examples.
The Hexastyle Temples at Rhamnus , Sunium, Egina , Eleusis , and Phygalia, are not suffi-ciently perfect to enable us to decide whether our principles would apply to them; butfrom the judgment we can form from their remains, they appear to have been all comprisedin a square and a half, and their entablatures and pediments in the proportion of a thirdof the whole.
The Hexastyle Temple at Segesta in Sicily is sufficiently perfect to enable us to judge ofits entire proportions.
