width of the rail is to be one-third of the pannel, and its 
cymatium a sixth part of the rail itself. The width of the 
inner styles is one half of the rail, and the raising (replum) 
four sixths of the rail. The styles nearest the dressings 
are made one half of the rail. If the doors are folding, the 
height remains the same, but the width is to be increased. 
If in four folds, the height is to be increased. The Attic 
doors are made of the same proportion as the Doric, ex¬ 
cept that, in the dressings, the fascia return within the 
cymatium; and these are proportioned so, that exclusive 
of the cymatium, they are to be two sevenths. These 
doors are not to be inlaid (cerostrata), nor in two folds, 
but single folded, and to open outwards. I have ex¬ 
plained, to the best of my power, the proportions used in 
setting out Doric, Ionic, and Corinthian temples, accord- 
ing to the approved methods. I shall now treat of the 
arrangement of Tuscan temples, and how they ought to 
be built.
