desolate epoch has come down to our days to show us what became of the ancient splendour of Egypt under the Hyksôs. We witness under the fifteenth and sixteenth dynasties a fresh shipwreck of Egyptian civilization. Vigorous as it had been, the impulse given to it by the Usurtasens suddenly stops; the series of monuments is interrupted, and Egypt informs us by her very silence of the calamities with which she was smitten."[15] It was, fortunately, not the entire country that was overrun. So far as appears, the actual occupation of Egypt by the Hyksôs was confined to the Delta, to the Lower Nile valley, and to the district of the Fayoum. Elephantine, Thebes, Abydos, escaped the destroyers, and though forced to certain formal acts of submission, to an acknowledgment of the Hyksôs suzerainty, and to the payment of an annual tribute, retained a qualified independence. The Theban monuments of the eleventh and twelfth dynasties were undisturbed. Even in Lower Egypt there were structures that suffered little or nothing at the conqueror's hands, being too humble to attract his attention or too massive to yield to the means of destruction known to him. Thus the pyramids scarcely suffered, though it is possible that at this time their sanctity was first violated and their contents rifled. The great obelisk of Usurtasen I., which still stands at Heliopolis, was not overthrown. The humbler tombs at Ghizeh, so precious to the antiquary, were for the most part untouched. Amenemhat's buildings in the Fayoum may have been damaged, but they were not demolished. Though Egyptian civilization received a rude shock from the invasion, it was not altogether swallowed up or destroyed; and when the deluge had passed it emerged once more, and soon reached, and even surpassed, its ancient glories.
