From the time of the 19th dynasty, with a slight revival under the Bubastite kings of the 22nd dynasty, Egypt sank through a long period of decay, till her misfortunes were consummated by the invasion of the Persians under Cambyses, 525 B.C. From that time she served in a bondage more destructive, if not so galling, as that of the Shepherd domination, till relieved by the more enlightened policy of the Ptolemys. Under them she enjoyed as great material prosperity as under her own Pharaohs; and her architecture and her arts too revived, not, it is true, with the greatness or the purity of the great national era, but still with much richness and material splendour. This was continued under the Roman domination, and, judging from what we find in other countries, we would naturally expect to find traces of the influence of Greek and Roman art in the buildings of this age. So little, however, is this the case, that before the discovery of the reading of the hieroglyphic signs, the learned of Europe placed the Ptolemaic and Roman temples of Denderah and Kalábsheh before those of Thebes in order of date; and could not detect a single moulding in the architectural details, nor a single feature in the sculpture and painting which adorned their walls, which gave them a hint of the truth. Even Cleopatra the beautiful is represented on these walls with distinctly Egyptian features, and in the same tight garments and conventional forms as were used in the portrait of Nophre Ari, Queen of Rameses, or in those of the wives of the possessors of tombs in the age of the pyramids, 3000 years before. Egypt in fact conquered her conquerors, and forced them to adopt her customs and her arts, and to follow in the groove she had so long marked out for herself, and followed with such strange pertinacity. Some of the temples of this age are, as far as dimensions and richness of decorations are concerned, quite worthy of the great age, though their plans and arrangements differ to a considerable extent. There is no longer any hesitation as to whether they should be called temples or palaces, for they all are exclusively devoted to worship,—and to the worship of a heavenly God, not of a deified king. What these arrangements are will be well understood from the annexed plan of that of Edfû (Woodcut No. 37), which, though not the largest, is the most complete of those remaining. It is 450 ft. in length and 155 in width, and covers upwards of 70,000 ft.; its dimensions may be said to be equal to those of the largest of our mediæval cathedrals (Cologne or Amiens, for instance). Parts only—viz., the court C, and areas M M M—of the whole structure are roofed, and therefore it can scarcely be compared with buildings entirely under one roof. [Illustration: 37.
