the lintel, place the frieze of the doorway, of the same height as the lintel, and having a Doric cymatium and Lesbian astragal carved upon it. Let the corona and its cymatium at the top of all be carved without ornamentation, and have a projection equal to its height. To the right and left of the lintel, which rests upon the jambs, there are to be projections fashioned like projecting bases and jointed to a nicety with the cymatium itself.
3. If the doorways are to be of the Ionic style, the height of the aperture should be reached in the same manner as in the Doric. Let its width be determined by dividing the height into two and one half parts and letting one of them form the width at the bottom. The diminutions should be the same as for Doric. The width of the faces of the jambs should be one fourteenth of the height of the aperture, and the cymatium one sixth of the width. Let the rest, excluding the cymatium, be divided into twelve parts. Let three of these compose the first fascia with its astragal, four the second, and five the third, the fasciae with their astragals running side by side all round.
4. The 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.
5. The rails will be apportioned thus: divide the height into five parts, of which assign two to the upper portion and three to the lower; above the centre place the middle rails; insert the others at the top and at the bottom. Let the height of a rail be one third of the breadth of a panel, and its cymatium one sixth of the rail. The width of the meeting-stiles should be one half the rail, and the cover-joint two thirds of the rail. The stiles toward
