Anatomical machines Anatomical machines The anatomical machines (Italian: "macchine anatomiche") are a couple of anatomical models reproducing the human circulatory system, exposed in the Cappella Sansevero in Naples. Realised in the second half of the 18th century, they are built on top of a couple of human skeletons, a male and a female. The reproduction of the vessel system was realised with metal wire, wax and silk, but because of its richness in details, for a long time it was believed that it was of natural origin instead. The models were commissioned by Raimondo di Sangro, prince of Sansevero, and realised by
18th century and the classical period (including Joseph Haydn and Wolfgang Amadeus Mozart). The 18th century also marked the end of the Polish–Lithuanian Commonwealth as an independent state. The once-powerful and vast kingdom, which had once conquered Moscow and defeated great Ottoman armies, collapsed under numerous invasions. Its semi-democratic government system was not robust enough to rival the neighboring monarchies of the Kingdom of Prussia, the Russian Empire and the Austrian Empire which divided the Commonwealth territories between themselves, changing the landscape of Central European politics for the next hundred years.
