As a matter of fact, we find that the axes of the temples have been changed, and have been freely changed; that there has been a great deal of work done on many of the temples which are not oriented to the sun, in order to give them a twist. Once a solar temple, a solar temple for thousands of years; once a star temple, only _that_ star temple for something like 300 years, so that the conditions were entirely changed. We get cases in which the axis of a temple has had its direction changed, and others in which, where it has been difficult or impossible to make the change in a temple, the change of amplitude has been met by putting up a new temple altogether. We are justified in considering such temples as a series in which, instead of changing the orientation of a pre-existing temple, a new temple has been built to meet the new condition of things. That, I think, is a suggestion which we are justified in making to Egyptologists on astronomical grounds. For an instance, I may refer to the well-known temple at Medînet-Habû. We have there two temples side by side--a large temple, which was built later, with its systems of pylons and sanctuaries; a smaller temple, with outside courts, and, again, a sanctuary built much earlier. The direction of these two temples is very different; there is a difference of several degrees. It is very difficult indeed to understand why these two structures should have been built in that way if there were not some good reason for it. The best hitherto found is the supposed symmetrophobia of the Egyptians. [Illustration: PLAN OF TWO TEMPLES AT MEDÎNET-HABÛ.] We find the same thing in Greece. There is the old Parthenon, a building which may have been standing at the time of the Trojan war, and the new Parthenon, with an outer court very like the Egyptian temples, but with its sanctuary more nearly in the centre of the building. It was by the difference of direction of these two temples at Athens that my attention was called to the subject. [Illustration: THE BENT AXIS OF THE TEMPLE OF LUXOR, LOOKING TOWARD THE SANCTUARY.]
