alt="Fig 29.--Plan of main gate, second fortress of Abydos. "/> Fig 29.--Plan of main gate, second fortress of Abydos. These precautions sufficed against sap and scaling; but the gates remained as open gaps in the circuit. It was upon these weak points that besiegers and besieged alike concentrated their efforts. The fortress of Abydos had two gates, the main one being situate at the east end of the north front (fig. 29).
Fig 30.--Plan of south-east gate, second fortress of Abydos. A narrow cutting (A), closed by a massive wooden door, marked the place in the covering wall. Behind it was a small
place d'armes (B), cut partly in the thickness of the wall, and leading to a second gate (C) as narrow as the first. When, notwithstanding the showers of missiles poured upon them from the top of the walls, not only in front, but also from both sides, the attacking party had succeeded in carrying this second door, they were not yet in the heart of the place.
Fig 31.--Plan of gate, fortress of Kom el Ahmar. They would still have to traverse an oblong court (D), closely hemmed in between the outer walls and the cross walls, which last stood at right angles to the first. Finally, they must force a last postern (E), which was purposely placed in the most awkward corner. The leading principle in the construction of fortress-gates was always the same, but the details varied according to the taste of the engineer. At the south-east gate of the fort of Abydos (fig. 30) the
place d'armes between the two walls is abolished, and the court is constructed entirely in the thickness of the main wall; while at Kom el Ahmar, opposite El Kab (fig. 31), the block of brickwork in the midst of which the gate is cut projects boldly in front.
Fig 32.--Plan of the walled city at El Kab. The posterns opening at various points facilitated the movements of the garrison, and enabled them to multiply their sorties.
The same system of fortification which was in use for isolated fortresses was also employed for the protection of towns. At Heliopollis, at Sãn, at Sais, at Thebes, everywhere in short, we find long straight walls forming plain squares or parallelograms, without towers or bastions, ditches or outworks. The thickness of the walls, which varied from thirty to eighty feet, made such precautions needless. The gates, or at all events the principal ones, had jambs and lintels of stone, decorated with scenes and inscriptions; as, for instance, that of Ombos, which Champollion beheld yet in situ, and which dated from the reign of Thothmes III. The oldest and best preserved walled city in Egypt, namely, El Kab, belongs probably to the ancient empire (fig. 32). The Nile washed part of it away some years ago; but at the beginning of the present century it formed an irregular quadrilateral enclosure, measuring some 2,100 feet in length, by about a quarter less in breadth. The south front is constructed on the same principles as the wall at Kom es Sultan, the bricks being bedded in alternate horizontal and concave sections. Along the north and west fronts they are laid in undulating layers from end to end. Fig 33.--Plan of walled city at Kom Ombo. The thickness is thirty-eight feet, and the average height thirty feet; and spacious ramps lead up to the walk upon the walls. The gates are placed irregularly, one in each side to north, east, and west, but none in the south face; they are, however, in too ruinous a state to admit of any plan being taken of them. The enclosure contained a considerable population, whose dwellings were unequally distributed, the greater part being concentrated towards the north and west, where excavations have disclosed the remains of a large number of houses. The temples were grouped together in a square enclosure, concentric with the outer wall; and this second enclosure served for a keep, where the garrison could hold out long after the rest of the town had fallen into the hands of the enemy.
The rectangular plan, though excellent in a plain, was not always available in a hilly country. Fig 34.--Plan of fortress of Kùmmeh. When the spot to be fortified was situate upon a height, the Egyptian engineers knew perfectly well how to adapt their lines of defence to the nature of the site. At Kom Ombo (fig. 33) the walls exactly followed the outline of the isolated mound on which the town was perched, and presented towards the east a front bristling with irregular projections, the style of which roughly resembles our modern bastions. At Kûmmeh and Semneh, in Nubia, where the Nile rushes over the rocks of the second cataract, the engineering arrangements are very ingenious, and display much real skill. Ûsertesen III. had fixed on this pass as the frontier of Egypt, and the fortresses which he there constructed were intended to bar the water-way against the vessels of the neighbouring negro tribes. At Kûmmeh, on the right bank, the position was naturally strong (fig. 34). Fig 35.--Plan of fortress of Semneh. Upon a rocky height surrounded by precipices was planned an irregular square measuring about 200 feet each way. Two elongated bastions, one on the north-east and the other on the south-east, guarded respectively the path leading to the gate, and the course of the river. The covering wall stood thirteen feet high, and closely followed the line of the main wall, except at the north and south corners, where it formed two bastion-like projections. At Semneh, on the opposite bank, the site was less favourable. Fig 36.--Section of the platform at A B, of the preceding plan. The east side was protected by a belt of cliffs going sheer down to the water's edge; but the three other sides were well-nigh open (fig. 35). A straight wall, about fifty feet in height, carried along the cliffs on the side next the river; but the walls looking towards the plain rose to eighty feet, and bristled with bastion-like projections (A.B.) jutting out for a distance of fifty feet from the curtain wall, measuring thirty feet thick at the base and thirteen feet at the top, and irregularly spaced, according to the requirements of the defence. These spurs, which are not battlemented, served in place of towers. Fig 37.--Syrian fort. They added to the strength of the walls, protected the walk round the top, and enabled the besieged to direct a flank attack against the enemy if any attempt were made upon the wall of circuit. The intervals between these spurs are accurately calculated as to distance, in order that the archers should be able to sweep the intervening ground with their arrows. Curtains and salients are alike built of crude brick, with beams bedded horizontally in the mass. The outer face is in two parts, the lower division being nearly vertical, and the upper one inclined at an angle of about seventy degrees, which made scaling very difficult, if not impossible. The whole of the ground enclosed by the wall of circuit was filled in to nearly the level of the ramparts (fig. 36). Externally, the covering wall of stone was separated from the body of the fortress by a dry ditch, some 100 to 130 feet in width. Fig 38.--The town-walls of Dapür. 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.
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. Fig 39.--City of Kadesh, Ramesseum. 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,
