She was Macedonian not Greek. The Ptolemys were a line from the General who was Alexander the Greats top person. When Alexander died his Empire was divided. The Ptolemy's gained control of Egypt. She was however the first of her family, this is over 300 years, to actually consider herself as an Egyptian. She practiced the religion of the people, spoke the language (she actually spoke like 5 languages), wore the traditional pharoh attire. So ethnically she was Macedonian. Mentally she was Egyptian.
