One of the most famous tombs in all of Egypt was holding a family secret: another body.

After 20 years of fieldwork in the mountains of Gebel Asyut al-Gharbi—located near the ancient Egyptian city of Asyut—archaeologists discovered the grave of Idy, a priestess of the goddess Hathor. Idy was also known as the “Lady of the House,” which was a title reserved for prominent families. Her grave was found tucked behind a stone wall within the tomb of her father, Diefaihapi I, who was a regional governor of the ancient city and one of the most powerful people of his day. The find was dated to 1880 B.C.
