This plate is to be drawn three times the size of plate B. The section of the mouldings is to be drawn first, then lines drawn at an angle of 45° from the different corners of the mouldings. The vertical surfaces are to be rendered darker than the horizontal ones as shown in the top moulding in the first column. The mouldings in the second and fourth columns are to be rendered by the French method, drawing fine light parallel pencil lines and rendering by successive washes, as shown in the rendered illustrations. The mouldings in the third and fifth columns are to be rendered by grading directly, by the addition of water if the tone changes from dark to light or by the addition of tint if the tone changes from light to dark. The letters and the border lines are to be rendered as indicated. A margin of half an inch of white paper is to be left outside of the border lines.
Rendering of Doric Order. This plate is to be three times the size of plate C. The order is the same size as the order on plate VII, in the Roman Orders. For rendering the order, the plate on page 5, "Detail of Greek Doric Order", will serve as a guide. The background A should be graded from dark at the top to light at the bottom similar to the wash between the column and pilaster in the plate mentioned above. The mouldings may be put in by the French method as shown on page 28. The background B should be a light evenly graded wash similar to the upper part of the background in the frontispiece, "Fragments from Roman Temple", having the wash somewhat darker at the top and grading it out to very light at the bottom. No trees, etc., are to be shown in the background. The steps will have a very light wash, that on step C being hardly noticeable, the step D a slightly more pronounced wash, and the step E a little darker still, but very light in tone. Study the value scale to determine these gradations. The tablet with letters may be rendered similar to the tablet at the bottom of the plate mentioned before. Reflected shadows are to be put in and care should be taken to show the reflected lights in the shade.
This plate is to be drawn double the size of plate D. A margin one and one-half inches is to be left as a white border outside the border line. The "Doric Doorway from Roman Temple at Cori", page 27, will serve as a guide for rendering this plate. The window opening is to be rendered with an even dark wash, and the wall surface is to have a light tone. The shadows are indicated by a faint wash and are to be modeled and graded in such a way that they all have proper relative values.
This plate is to be drawn double the size of plate E, and a margin of an inch and a half of white is to be left outside of the border line. Plate XXXIII, in the Roman Orders, can be used as a guide, the Temple drawn there being of the same size required for this problem. If the flutes on the columns are put in, they should be drawn with watered ink so that they are not too pronounced. The shadows and the parts in shade are shown by a faint flat wash outlined by dotted lines. All the lights and shadows are to be carefully modeled in their proper relations to one another. The wall A1 and A2 is on a line with the rear wall of the Temple; hence the portion of the wall, A2, on the right of the Temple will be in shade, and the portion, A1 on the left will have a light tone over it to show that it is in the background. For the rendering of the spaces between the columns and the doorway, the plate "Detail from Temple of Mars Vengeur", page 18, will be helpful as well as for the rendering of the steps. The shadows on the steps will be similar in grading to the shadow of the altar on the steps. The bronze candelabra is to be rendered dark, care being taken to leave high lights of "White" on the round surfaces receiving the most direct light. For suggestions for rendering the bronze plate, page 32. In rendering background, the frontispiece, "Fragments from Roman Temple at Cori", will prove helpful.
