The Anatomical Machines, Giuseppe Salerno, 1763-64. "In the Underground Chamber, housed in two glass cases, are the famous Anatomical Machines - the skeletons of a man and woman with the artery & vein systems almost perfectly intact. The two anatomical studies are the most enigmatic objects in the Sansevero Chapel. After about two and a half centuries, it is still not known which procedures or materials were used to obtain such an exceptional preservation of the circulatory system."
