sphinx statues

The Great Sphinx is believed to be the most immense stone sculpture in the round ever made by man. However, it must be noted that the Sphinx is not an isolated monument and that it must be examined in the context of its surroundings. Specifically, like many of Egypt's monuments, it is a complex which consists not only of the great statue itself, but also of its old temple, a New Kingdom temple and some other small structures. It is also closely related to Khafre's Valley Temple, which itself had four colossal sphinx statues each more than 26 feet long.

The material of the Sphinx is the limestone bedrock of what geologists call the Muqqatam Formation, which originated fifty million years ago from sediments deposited at the bottom of sea waters that engulfed northeast Africa during the Middle Eocene period. An embankment formed along what is now the north-northwest side of the plateau. Nummulites, which are small, disk-shaped fossils named after the Latin word for 'coin', pack the embankment. These were once the shells of now extinct planktonic organisms. There was a shoal and coral reef that grew over the southern slope of the embankment. Carbonate mud deposited in the lagoon petrified into the layers from which the ancient builders, some fifty million years later, carved out the Great Sphinx.
