Had it not been for the odd-looking big toe on her right foot, the 3,000-year-old female mummy from burial chamber TT-95 in the Egyptian necropolis at Thebes-West probably wouldn't have attracted much attention. She was elderly at the time of her death— about 50 years old— but not remarkably so, and only moderately well preserved. But that big toe, archaeologists soon realized, was extraordinary. It consisted of three pieces of carved wood fitted onto her foot with leather straps, making it by far the world's oldest known prosthesis.
