300 Year Old “Exceptional” Prosthesis made of Gold and Copper Discovered in Poland

Archaeologists in Poland working on the excavation of the Church of St. Francis of Assisi in Krakow have found something new, described as the first discovery of its kind in the country. The body of a man has been revealed to have a medical prosthesis in his mouth, an artificial insert which allowed him to live with a cleft palate.
