The Great Sphynx of Giza was buried up to its neck in sand. You can see in an 1849 photo how it was just started being dug out. They continuously excavated, only finding out in the late 1920s that the Sphynx actually has a tail. The Great Sphynx is old… like, we’re closer to time to Cleopatra (born 69 BC) than she was to the building of the Sphynx (25th century BC).
Speaking of Cleopatra… the famous one whose death (and Mark Antony’s) ended the Ptolemaic pharaonic era and started Egypt’s period as a Roman vassal state - was “Cleopatra VII”. One has to realize that ancient Egyptian royal marriages were polygamous and incestuous. Parents often married siblings and their own children and co-ruled in order to preserve the dynasty and prevent fratricide. The Ptolemaic rulers usually named their sons Ptolemy and girls Cleopatra - with some exceptions. The last Cleopatra was only the great-grandchild of the first.
