They are mostly, like the pyramids, without ornament; but there is one remarkable tomb at Beni Ha an. which has a portico of two sixteen-sided and channeled columns in antis , the forms of which seem to prove the Egyptian origin of Grecian-Doric architecture. The Egyptian temples were remarkable, like the Pyramids, for their vast extent, ma ive structure, and admirable workmanship, but more elaborate in construction and elaborately decorated by means of color. The construction is that of the post and lintel, or upright and cro -beam, which has not since been employed on so extensive a scale, spans of over 30 ft. being bridged, in the Hypostyle Hall of Karnac, with single blocks of sandstone. The decoration is mainly pictorial, carved ornament being sparingly employed, and the modeling of structural parts limited to the shaping of the columns and of their capitals, which were in imitation of the buds or the blo oms of the lotus, and to large and simple moldings, concave and convex. All these temples are believed to have been erected during the 18th and 19th dynasties, 1820-1312 В.С. That Grecian monumental architecture was derived from that of Egypt is no longer seriously disputed.
