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 Robespierre. At first, many monarchies of Europe embraced Enlightenment ideals, but with the French Revolution they feared losing their power and formed broad coalitions for the counter-revolution. The Ottoman Empire experienced an unprecedented period of peace and economic expansion, taking part in no European wars from 1740 to 1768. As a consequence the empire did not share in Europe's military improvements during the Seven Years' War (1756–1763), causing its military to fall behind and suffer defeats against Russia in the second half of the century. 18th century music included the Baroque period (including Johan Sebastian Bach and George Frederic Handel)
