This masterpiece of art and technology is the actual mirror of Princess Sat-Hathor-Yunet. She was one of the daughters of Senusert the Second.
The silver disk of the mirror is attached to the obsidian handle through a small tongue. The handle is in the shape of an open papyrus topped by the head of Hathor, made out of gold with eyes of lapis lazuli.
Through the depiction of the goddess Hathor, the mirror imparted beauty and joy to its owner.
