The Lorraines' interest in medicine is documented by some exceptional artifacts, of which a selection is on display. The 40 clay obstetrical models were intended for teaching purposes. Most were made by Giuseppe Ferrini under the guidance of Giuseppe Galletti (?-1819), professor of obstetrics at the Arcispedale di Santa Maria Nuova. The 30 surgical instrument kits were designed by the physician Giovanni Alessandro Brambilla and manufactured by the cutler Joseph Malliard. The Habsburg Emperor Joseph II gave them as a gift to his brother Peter Leopold.
