+LATER TEMPLES.+ After the architectural inaction of the Decadence came a marvellous recrudescence of splendor under the Ptolemies, whose Hellenic origin and sympathies did not lead them into the mistaken effort to impose Greek models upon Egyptian art. The temples erected under their dominion, and later under Roman rule, vied with the grandest works of the Ramessidæ, and surpassed them in the rich elaboration and variety of their architectural details. The temple at Edfou (Figs. 9, 10, 14) is the most perfectly preserved, and conforms most closely to the typical plan; that of Isis, at Philæ, is the most elaborate and ornate. Denderah also possesses a group of admirably preserved temples of the same period. At Esneh, and at Kalabshé and Kardassy or Ghertashi in Nubia are others. In all these one notes innovations of detail and a striving for effect quite different from the simpler majesty of the preceding age (Fig. 14). One peculiar feature is the use of screen walls built into the front rows of columns of the hypostyle hall. Light was admitted above these walls, which measured about half the height of the columns and were interrupted at the centre by a curious doorway cut through their whole height and without any lintel. Long disused types of capital were revived and others greatly elaborated; and the wall-reliefs were arranged in bands and panels with a regularity and symmetry rather Greek than Egyptian.

FRONT OF HYPOSTYLE HALL.] +ARCHITECTURAL DETAILS.+ With the exception of a few purely utilitarian vaulted structures, all Egyptian architecture was based on the principle of the lintel. Artistic splendor depended upon the use of painted and carved pictures, and the decorative treatment of the very simple supports employed. Piers and columns sustained the roofs of such chambers as were too wide for single lintels, and produced, in halls like those of Karnak, of the Ramesseum, or of Denderah, a stupendous effect by their height, massiveness, number, and colored decoration. The simplest piers were plain square shafts; others, more elaborate, had lotus stalks and flowers or heads of Hathor carved upon them. The most striking were those against whose front faces were carved colossal figures of Osiris, as at Luxor, Medmet Abou, and Karnak (Fig. 15). The columns, which were seldom over six diameters in height, were treated with greater variety; the shafts, slightly tapering upward, were either round or clustered in section, and usually contracted at the base. The capitals with which they were crowned were usually of one of the five chief types described below. Besides round and clustered shafts, the Middle Empire and a few of the earlier monuments of the New Empire employed polygonal or slightly fluted shafts (see p. 11), as at Beni Hassan and Karnak; these had a plain square abacus, with sometimes a cushion-like echinus beneath it. A round plinth served as a base for most of the columns.
