4The upper members of the door-way are the same as those of the Doric. The trusses (ancones), or prothyrides, which are carved on the right and left, reach to the bottom of the level of the architrave, exclusive of the leaf. Their width on the face is one-third of the dressing, and at the bottom one fourth part less. The wooden doors are to be so put together, that the hinge styles (scapi cardinales) may be one-twelfth of the height of the aperture. The pannels (tympana) between the styles are to be three out of twelve parts in width.
4The cornices of Ionic doorways should be constructed in the same manner as those of Doric, in due proportions. The consoles, otherwise called brackets, carved at the right and left, should hang down to the level of the bottom of the lintel, exclusive of the leaf. Their width on the face should be two thirds of the width of the jamb, but at the bottom one fourth slenderer than above.
Doors should be constructed with the hinge-stiles one twelfth of the width of the whole aperture. The panels between two stiles should each occupy three of the twelve parts.
