Eugène-Emmanuel Viollet-le-Duc,
How to build a house
(1874)
“ Let us begin, then, by drawing a folding-door. We shall make the framing of this door of wood 13⁄4 inch thick. We call the outer upright pieces (Fig. 56) the hanging-stiles; the pieces, A, the meeting-stiles; the horizontal pieces between them, the rails. The stiles and the top and bottom rails shall be each 41⁄4 inches wide, the intermediate uprights, or munton, 2 inches. Now each leaf—deducting 1⁄2 an inch for the rebate, or overlap, in the middle—will be 2 feet wide, since the doorway must have an opening of 4 feet: deducting 41⁄4 in. ”
