Passing on we find ourselves in a dark tomb copied from one at Beni Hassan. It is the earliest piece of architecture in the Crystal Palace, its date being about 1660 B.C. The original tomb is cut in the solid chain of rocks that forms a boundary on the east of the Nile, separating the sandy desert from the fertile valley of the river. Although architectural remains exist in Egypt of a much earlier date than this tomb, it still possesses great value to us, for it may be considered as exhibiting the first _order_ of Egyptian columns, which was employed in constructing buildings at as remote a period as two thousand years before Christ; this fluted column in another respect claims our attention, for there can be but little doubt that it supplied the Greeks with the model of their early Doric. The original tomb has but one instead of four entrances as here represented, and is accordingly more gloomy and impressive. What is lost in sombre effect, however, is made up to the visitor in convenience. Passing out, we behold, in front of us, a beautiful colonnade, or portico, from the Island of Philöe, and of the same period as the Egyptian wall which we first saw fronting the Nave. Within this we cannot fail to remark the scattered statues, especially the Egyptian Antinous, executed during the Roman rule, the life-like development of whose limbs, representing, as it no doubt does, the Egyptian type, is sufficient to convince us that when Egyptian art was not tied down by the hierarchical yoke, it was capable of producing works of truth and merit. Another work of art, executed when the country was under the Greek yoke, is the remarkable bas-relief portrait of Alexander the Great, inscribed in hieroglyphics and Greek characters. The Greek name is spelt wrongly--a sufficient proof that the work of art is from the hand of an Egyptian artist. Amidst the statues will be found two circular-headed stones--copies of the celebrated Rosetta stone (so called from having been found at the little town of Rosetta, near Alexandria) from which Dr. Young and Champollion obtained a key to the deciphering of hieroglyphics. The stone is engraved in three characters: Hieroglyphic, Enchorial--the writing of the country--and Greek; the inscription is an address from the priests to the Greek King of Egypt, Ptolemy V., in which the sovereign’s praises are set forth, and orders are given to set up a statue of the king, together with the address, in every temple. The date of this interesting remnant of Egyptian manners and customs is about 200 years before the Christian era.
