"It is probable that the walls of Karnak served all three purposes. There are four of them, connected one with another by avenues of sphinxes, and all the sacred parts of the building, except a few chapels, are in one of the four inclosures.... Their height was at least sufficient to prevent any part of the inside from being overlooked from any quarter of the city, so that the ceremonies in the halls, under the colonnades, or upon the lakes could be proceeded with in strict isolation from the outer world.[304] We may therefore perceive that, on certain occasions, these inclosures would afford a sanctuary which could not easily be violated, while they would keep all those who had not been completely initiated at a respectful distance from the holy places within."[305]
These walls were pierced in places by stone doorways, embedded in the masses of crude brick, whose highest parts always rose more or less above the battlements of the wall ([Fig. 206]). At those points where the sphinx avenues terminated, generally at the principal entrance of the temple but sometimes at secondary gateways, these portals expanded into those towering masses which by their form as well as their size, so greatly impress the traveller who visits the ruins of ancient Egypt. These masses have by common consent been named pylons. They seem to have been in great favour with the architects of Egypt, who succeeded by their means in rendering their buildings still more original than they would have been without them.[306]

The pylon is composed of three parts intimately allied one with another; a tall rectangular doorway is flanked on either hand by a pyramidal mass rising high above its crown. Both portal and towers terminate above in that hollow gorge which forms the cornice of nearly all Egyptian buildings. Each angle of the towers is accentuated by a cylindrical moulding, which adds to the firmness of its outlines. This moulding bounds all the flat surfaces of the pylon, which are, moreover, covered with bas-reliefs and paintings. It serves as a frame for all this decoration, which it cuts off from the cornice and from the uneven line which marks the junction of the sloping walls with the sandy soil. From the base of the pylon spring those vertical masts from whose summits many coloured streamers flutter in the sun.[307] In consequence of the inclination of the walls, these masts, being themselves perpendicular, were some distance from the face of the pylon at its upper part. Brackets of wood were therefore contrived, through which the masts passed and by which their upright position was preserved; without some such support they would either have been liable to be blown down in a high wind, or would have had to follow the inclination of the wall to which they were attached, which would have been an unsightly arrangement. The interiors of the pylons were partly hollow; they inclosed small chambers to which access was obtained by narrow staircases winding round a central square newel. The object of these chambers seems to have been merely to facilitate the manœuvring of the masts and their floating banners, because when the latter were in place, the small openings which gave light to the chambers were entirely obscured.
If the pylons had been intended for defensive purposes, the doors in their centres would have been kept in rear of the flanking towers, as in more modern fortifications. But instead of that being the case they are slightly salient, which proves conclusively that their object was purely decorative.
The pylon which we have taken as a type of such erections, is one of those which inclose a doorway opening in the centre of one of the sides of the brick inclosure, it may be called an external pylon, or a pro-pylon, to make use of the word proposed by M. Ampère, but in all temples of any importance several pylons have to be passed before the sanctuary is reached. At Karnak, for instance, in approaching the great temple from the temple of Mouth, the visitor passes under four pylons, only one of which, the most southern, is connected with the inclosing wall. So, too, on the west. After passing the pylon in the outer wall, another has to be passed before the hypostyle hall is reached, and a third immediately afterwards. Then, behind the narrow court which seems to cut the great mass of buildings into two almost equal parts, there are three more at very slight intervals. Thus M. Mariette counts six pylons, progressively diminishing in size, which lie in the way of the visitor entering Karnak by the west and passing to the east. At Luxor there are three.
A glance at our general view of the buildings of Karnak will give a good idea of the various uses to which the Egyptian architect put the pylon.[308] There is the pro-pylon; there are those pylons which, when connected with curtain walls, separate one courtyard from another; there are those again, which, placed immediately in front of the hypostyle halls, form the façades of the temples properly speaking. The temple is always concealed behind a pylon, whose summit rises above it while its two wings stretch beyond it laterally until they meet the rectangular wall which incloses the sanctuary.
The dimensions of pylons vary with those of the temples to which they belong. The largest still existing is the outer pylon of the great temple of Karnak. It was constructed in Ptolemaic times. Its two chief masses are 146 feet high, or about equal to the Vendôme column in Paris. This pylon is 376 feet wide at the widest part and 50 feet thick. The first pylon at Luxor, which was built by Rameses II., is less gigantic in its proportions than this; it is, however, 76 feet high, each of its two great masses is 100 feet wide, and the portal in the middle is 56 feet high (see [Fig. 207]).
In those temples which were really complete, obelisks were erected a few feet in front of the pylons, and immediately behind the obelisks, in contact with the pylons themselves, were placed those colossal statues by which every Egyptian monarch commemorated his connection with the structures which were reared in his time. The obelisks are generally two in number, the colossi vary from four to six for each pylon, according to the magnificence of the temple. The obelisks range in height from about 60 to 100 feet, and the statues from 20 to 45 feet.[309] Obelisks and colossal statues seem to have been peculiarly necessary outside the first, or outer, pylon of a temple. This produced an effect upon the visitor at the earliest moment, before he had entered the sacred inclosure itself. But they are also to be found before the inner pylons, a repetition which is explained by the fact that such temples as those of Karnak and Luxor were not the result of a single effort of construction. Each of the successive pylons which met the visitor during the last centuries of Egyptian civilization had been at one time the front of the whole edifice.
