Farther south are the stupendous ruins of Thebes on both sides of the river, the temple of Esna, the ruins and tombs of El Kab, the temple of Edfu, the quarries of Silsila and the temple of Ombos, followed by the inscribed rocks of the First Cataract, the tombs and quarries of Assuan and the temples of Philae.
The chief of these was limestone of varying degrees of fineness, composing the cliffs which lined the valley from the apex of the Delta to the neighborhood of El Kab; the best quality was obtained on the east side opposite Memphis from the quarries of Turra and Masgra.
The capital of Upper Egypt was Nekheb, now represented by the ruins of El Kab, with the royal residence across the river at Nekhen (Hieraconpolis); that of Lower Egypt was at Buto (PutO or Dep) in the marshes, with the royal residence in the quarter called Pe.
Nekhbi, goddess of El Kab, represented the Upper or Southern Kingdom, which was also under the tutelage of the god Seth, the goddess Buto and the god Horus similarly presiding over the Lower Kingdom.
West of the Nile there are a few oases-- those of Selima, Zaghawa and El Kab - but this district, part of the Libyan Desert, is even more desolate than the Nubian Desert.
