Well, the part about grinding up mummies is true enough. Natural resources get processed.
"The Western pop cultural canon of ancient Egypt" seems to be a red herring, though; Cleopatra is not part of or associated with ancient Egypt. She would be at the tail end of the Hellenistic period or the beginning of the Roman Empire. The New Kingdom ended a thousand years before she came to power.
(Hey, why do we call it "the New Kingdom"?)
