Egyptian antiquities authorities Saturday unveiled ancient workshops and tombs they say were discovered recently at a Pharaonic necropolis just outside the capital Cairo. The spaces were found in the sprawling necropolis of Saqqara, which is a part of Egypt’s ancient capital of Memphis, a UNESCO World Heritage site. Mostafa Waziri, secretary-general of the Supreme Council of Antiquities, said the workshops had been used to mummify humans and sacred animals. They date back to the 30th Pharaonic Dynasty (380 BC to 343 BC) and Ptolemaic period (305 BC to 30 BC), he said.
