I have already mentioned that a sphinx-guarded street, about two miles long, ran from Luxor to Karnak. I have also pointed out that the north-west angle of the great enclosure of Karnak was connected, to the eye, with the temples of the western Háger. The precise spot upon the Háger where a temple had been made conspicuous to the eye from Karnak, was what is now called Assassef. Of course from Assassef the lofty structures of Karnak were in full view. In order to place the temple at Assassef reciprocally in view to the spectator standing at Karnak, it was necessary to remove a part of the natural rock wall of the eastern side of the valley of Assassef, and this had been done. The distance from Karnak to Assassef is somewhat over three miles. From this point temples and temple-palaces were continuous along the edge of the Háger, in front of the Necropolis, as far as the western extremity of the Royal Street. Thus was completed the grand Theban Parallelogram. The circuit of the four sides measured, I suppose, about ten miles. It included every one of the great structures of Luxor, Karnak, and Thebes. There can be no doubt but that the lofty propylæa, and obelisks of Luxor and Karnak were intended to be seen from a distance. As the site of Thebes was, of itself, somewhat elevated above the sites of Luxor and Karnak, there was no occasion for obelisks at Thebes; as also they would have been backed by the mountains to one looking from the other side of the river, they would have been inconspicuous, and therefore this architectural form was not used at Thebes: though, indeed, I believe no instance remains to show that it was ever used on that side of the valley, on which the sun set.
