N. of Cairo, on the eastmost branch of the Nile; it was the centre of Egyptian learning; Solon and Plato are said to have studied there, and Potiphar was one of its chief priests; the famous obelisk Pharaoh's Needle stands near; and Cleopatra's Needle, now on the Thames Embankment, was originally of this city.
