But the plain at the foot of the range offered all that the architect could wish. It was still within the district consecrated to the dead, and yet its level surface presented no obstacles to an unlimited extension of any buildings which might be placed upon it. We have here then the facts which determined the course of the Egyptian architects. In the space inclosed between the left bank of the river and the first slopes of the Libyan chain, certain edifices were raised which are still, in great part, extant. Their funerary signification was never completely understood, in spite of the confused hints to that effect given by the Greek writers, until within the last few years. To Mariette belongs the credit of having at last removed all doubt on the subject. It is probable enough that the number of these buildings was formerly much greater than it is at present, but those which have come down to us are still in sufficiently good preservation to enable us to discern and define their true character, a character which was doubtless common to all the temples on the left bank of the Nile. They were certainly temples. Their general arrangements do not differ from those of other religious edifices, both in Thebes itself, and elsewhere in Egypt. There is, however, a difference which was not perceived until the texts which contained the history of each temple and of the prince who claimed the credit of its erection were deciphered. The famous buildings at Luxor and Karnak may be taken as typical examples of the temple, properly speaking, in its richest and most complete development. The translation of the inscriptions and royal ovals which cover their walls has sufficed to show that they were national monuments, public sanctuaries consecrated by the king, as the representative of the people, to the worship of those great deities who were at once the principles of life and the faithful protectors of the Egyptian race. Century after century they never ceased to found such temples, to increase and to embellish them. From the princes of the twelfth dynasty down to the Ptolemies, and even to the Roman emperors, every successive family which occupied the throne held it a point of honour to add to the creations of its predecessors. One prince built a hypostyle hall, or a court surrounded by a colonnade; another added to the long rows of human or ram-headed sphinxes which lined the approaches; a third added a pylon, and a fourth a laboriously chiselled obelisk. Some kings, who reigned in periods of recuperation after civil war or barbaric invasion, set themselves to repair the damage caused by time and the violence of man. They strengthened foundations, they lifted fallen columns, they restored the faded colours of the painted decorations. The foreign conquerors themselves, whether Ethiopians, Persians, or Greeks, as soon as they believed themselves to have a firm hold upon the country, set themselves with zeal to obliterate the traces of their own violence.
