In a depression to the south of Khafre's pyramid at Giza near Cairo sits a huge creature with the head of a human and a lion's body. This monumental statue, the first truly colossal royal sculpture in Egypt, known as the Great Sphinx, is a national symbol of Egypt, both ancient and modern. It has stirred the imagination of poets, scholars, adventurers and tourists for centuries and has also inspired a wealth of speculation about its age, its meaning, and the secrets that it might hold.
