Erechtheum Doorway. A doorway and window from the Erechtheum at Athens are drawn out in Figs. 83 and 84. In Fig. 84 the complete doorway (Fig. 85) is shown, while in Fig. 83 the details are drawn out at a larger scale. The window is placed inside the door opening, with the sections of the architrave and sill placed immediately above it. The proportions of this doorway and window are typical of those employed in the best Greek structures; and it will be observed that the width of the opening at the top is narrower in each case than it is at the bottom, the lines tapering to some vanishing point on the center line above, where they would intersect. The width of the architrave narrows in the same proportion as it nears the top of the opening. This will sufficiently indicate, from an example of the best period, the general principles followed by the Greeks in their use of doors and windows.

Stele Crestings. The cresting ornaments shown in Fig. 86 were used by the Greeks to finish off the tops of their monumental stelae or shafts, one of which is shown at full height in the upper central portion of this drawing. The carving occurs on the front and rear of the shaft, which is of comparatively small thickness, being as narrow as the material employed will allow. The Greeks devised a great variety of ornaments for this purpose, all similar in type to the ones here illustrated; but the eight examples reproduced may be considered as fairly representative of some of the best general types.
