Nile cruise boats are moored in front of the temple of Kom Ombo. The temple was built in the time of the Ptolemies, pharaohs descended from a general of Alexander the Great, who conquered the Persians in 332 BC and was crowned pharaoh of Egypt. Upon his death much of his empire was divided up among his generals and the Ptolemic period of Egyptian history began. This was Cleopatra's family. The smoke in the photograph is from nearby sugar refineries.
