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.
And the lowest of all was the sandstone school of Silsila, which is always the worst.
Of the prehistoric age there are many rock carvings, associated with others of later periods: they principally remain on the sandstone rocks about Silsila, and their age is shown by the figures of ostriches which were extinct in later times.
The rock temple at Silsila and a shrine at Jebel Adda are also his.
The rock shrines at Silsila are of small importance.
