This wall closely followed the main outline, and rose to a height which varied according to the situation from six to ten feet above the level of the plain. On the northward side it was cut by the winding road, which led down into the plain. These arrangements, skilful as they were, did not prevent the fall of the place. A large breach in the southward face, between the two salients nearest to the river, marks the point of attack selected by the enemy. [Illustration: Fig. 37.--Syrian fort.] [Illustration: Fig. 38.--The town-walls of Dapür.] [Illustration: Fig. 39.--City of Kadesh, Ramesseum.] [Illustration: Fig. 40.--Plan of the pavilion of Medinet Habu.] [Illustration: Fig. 41.--Elevation of pavilion, Medinet Habû.] New methods of fortification were revealed to the Egyptians in the course of the great Asiatic wars undertaken by the Pharaohs of the Eighteenth Dynasty. The nomadic tribes of Syria erected small forts in which they took refuge when threatened with invasion (fig. 37). The Canaanite and Hittite cities, as Ascalon, Dapur, and Merom, were surrounded by strong walls, generally built of stone and flanked with towers (fig. 38). Those which stood in the open country, as, for instance, Qodshû (Kadesh), were enclosed by a double moat (fig. 39). Having proved the efficacy of these new types of defensive architecture in the course of their campaigns, the Pharaohs reproduced them in the valley of the Nile. From the beginning of the Nineteenth Dynasty, the eastern frontier of the Delta (always the weakest) was protected by a line of forts constructed after the Canaanite model. The Egyptians, moreover, not content with appropriating the thing, appropriated also the name, and called these frontier towers by the Semitic name of _Magdilû_ or Migdols. For these purposes, or at all events for cities which were exposed to the incursions of the Asiatic tribes, brick was not deemed to be sufficiently strong; hence the walls of Heliopolis, and even those of Memphis, were faced with stone. Of these new fortresses no ruins remain; and but for a royal caprice which happens to have left us a model Migdol in that most unlikely place, the necropolis of Thebes, we should now be constrained to attempt a restoration of their probable appearance from the representations in certain mural tableaux. When, however, Rameses III. erected his memorial temple[3] (figs. 40 and 41), he desired, in remembrance of his Syrian victories, to give it an outwardly military aspect. Along the eastward front of the enclosure there accordingly runs a battlemented covering wall of stone, averaging some thirteen feet in height. The gate, protected by a large quadrangular bastion, opened in the middle of this wall. It was three feet four inches in width, and was flanked by two small oblong guard-houses, the flat roofs of which stood about three feet higher than the ramparts. Passing this gate, we stand face to face with a real Migdol. Two blocks of building enclose a succession of
