“Statue of Idet & Ruiu, two women who have been identified as possibly mother and daughter, sisters, or a same-sex couple. Idet is given priority by the artist who placed her on the right, and is given the title "Lady of the House". Limestone. New Kingdom, 18th Dynasty, 1480-1390 BCE. From the Theban necropolis, Egypt. (Egyptian Museum of Turin)”
