About 60 drawings and hieroglyphic inscriptions, dating back around 5,000 years, have been discovered at a site called Wadi Ameyra in Egypt’s Sinai Desert. Carved in stone, they were created by mining expeditions sent out by early Egyptian pharaohs, archaeologists say. They reveal new information on the early pharaohs. For instance, one inscription the researchers found tells of a queen named Neith-Hotep who ruled Egypt 5,000 years ago as regent to a young pharaoh named Djer. Archaeologists estimate that the earliest carvings at Wadi Ameyra date back around 5,200 years, while the most recent date to the reign of a pharaoh named Nebre, who ruled about 4,800 years ago.
