According to archeological sources, a bronze leg manufactured in about 300 BC in Rome has been considered the world’s oldest prosthetic device until recently. It may be no longer true. A recent study carried out by researchers at the University of Manchester indicates that an artificial big toe, made in ancient Egypt sometime between 1000 BC and 600 BC, could qualify for the title of the oldest prosthesis in history, France Press reports. The big toe was discovered during an excavation in 2000. It is currently on display in the Cairo Museum.
