Egyptian history begins with Menes, the founder of the united monarchy, and of the First historical dynasty. Our glimpses of the age that preceded him--the age of the followers of Horus, as the Egyptians termed it--are few and scanty. Egypt was divided into several kingdoms, which were gradually unified into two only, those of the north and the south. The northern kingdom was symbolised by the snake and papyrus, the southern kingdom by the vulture and aloe. The vulture was the emblem of Nekheb, the goddess of the great fortress whose ruins are now called El-Kab; and it is probable that the city of Nekhen, which stood opposite it on the western bank of the Nile, was once the capital of the south. However this may be, when Menes mounted the throne he was hereditary ruler of This, a city which adjoined the sacred burial-place of Osiris at Abydos, and of which Girgeh is the modern successor. Menes made himself master of the north, and so united all Egypt under one rule. He then undertook and carried through a vast engineering work, one of the greatest the world has ever seen. The Nile was turned aside out of its old channel under the Libyan cliffs into a new channel to the east. The dyke which forced the river from its old course still remains, and two or three thousand years before the bed of the valley had risen to its present level the destruction of the dyke would have meant the return of the Nile to its former path. North of the dyke English engineers have found that the alluvial soil bears witness to interference with the natural course of the river of a far-reaching kind, and its long straight course resembles that of a canal rather than of the naturally winding stream of the Nile. On the embankment thus won from the waters Menes built his capital, which bore the two names of Men-nefer or Memphis, "the Beautiful Place," and Hâ-ka-Ptah or Ægyptos, "the Temple of the Double of Ptah." On the north side of it, in fact, stood the temple of Ptah, the local god, the scanty remains of which are still visited by the tourist. In front of the shrine was the sacred lake across which, on days of festival, the image of the god was ferried, and which now serves as a village pond.
