The Sphinx at Gizeh, Pompey�s Pillar and Cleopatra�s Needle, 1804.

EGYPT - SEPTEMBER 04: Engraving by J Pass after Denon showing Ancient Egyptian artifacts. At the top are sculptures of musicians playing harps and other stringed instruments, and in the centre a patera (bas-relief ornament) with portraits of the gods Osiris and Isis. Europeans are measuring the head of the Great Sphinx (below centre). The 27-metre granite shaft called Pompey�s Pillar was in fact raised in honour of the Roman emperor Diocletian (245�313) in the 4th century, and is not connected with the Roman soldier Pompey (106-48 BC). Of the many Egyptian obelisks, two became known as Cleopatra�s Needle; one is in London and the other in New York.
