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
Anna Morandi Manzolini children. In 1755, her husband died, and she was left with very slender means of support. She received tempting offers from other universities, but she preferred to remain in her native city, Bologna. She closed a laborious and honored life in the city in 1774, at the age of 60 years. When her husband became ill with tuberculosis, she received special permission to lecture in his place. She became professor of anatomy upon his death in 1755. Knowledge of her talent in molding anatomical models spread throughout Europe and she was invited to the court of Catherine II of Russia
