If we examine the doorways of the temples themselves we shall there also find great variety in the manner in which they are combined architecturally with the walls in which they occur. [Illustration: FIG. 149.--Gateway in the inclosing wall of a Temple. Restored by Ch. Chipiez.] In the Temple of Khons the jambs of the door are one, architecturally, with the wall. The courses are continuous. The lintel alone, being monolithic, has a certain independence (Fig. 150). In the Temple of Gournah, on the other hand, the doorway forms a separate and self-contained composition. The jambs are monoliths as well as the lintel, and the latter, notwithstanding the great additional weight which it has to carry, does not exceed the former in section. At Abydos, on the other hand, the capital part which this stone has to play is indicated by the great size of the sandstone block of which it is composed (Fig. 154). [Illustration: FIG. 150.--Doorway of the Temple of Khons. _Description_, iii. 54.] [Illustration: FIG. 151.--Doorway of the Temple of Gournah. _Description_, ii. 42.] One of the doorways we have represented, that in Fig. 146, requires to be here mentioned again for a moment. Its lintel is discontinuous. The doorway in question dates from the Ptolemaic period, but there is undoubted evidence that the same form was sometimes used in the Pharaonic period for the openings in inclosing walls. There is a representation of such a door in a bas-relief at Karnak, where it is shown in front of a pylon and forms probably an opening in a boundary wall.[141] It was this representation that decided us to give a broken lintel to the doorway opposite to the centre of the royal pavilion at Medinet-Abou (Plate VIII.). This form of entrance may have originated in the desire to give plenty of head-room for the canopy under which the sovereign was carried, as well as for the banners and various standards which we see figured in the triumphal and religious processions of the bas-reliefs (Fig. 172, Vol. I.).

[Illustration: FIGS. 153, 154.--Windows in the Royal Pavilion at Medinet-Abou.] The royal pavilion at Medinet-Abou is the only building in Egypt which has preserved for us those architectural features which we call windows. They differ one from another, even upon this single building, as much as the doors. One of them (Fig. 153) is enframed like the doorway at Gournah; but the jambs are merely the ends of the courses which make up the wall, and their salience is very slight. On the other hand a window frame with a very bold relief (Fig. 154) is to be found in the same building. This window is a little work of art in itself. It is surmounted by a cornice, over which again appear various emblems carved in stone, making up one of the most graceful compositions to be found in Egyptian architecture.
