Сант-Андреа-делла-Валле
After the death of Federico Cesi, it was left to Cassiano dal Pozzo and Francesco Stelluti to conserve the precious inheritance of scientific instruments, books and research. Rather than see Cesi's library dispersed, Cassiano purchased it, with part of Cesi's natural history cabinet, in December 1633 and housed it with his own collection at Sant'Andrea della Valle. His financial and intellectual support helped the Lincei achieve its most lasting monument, "Il Tesoro Messicano", which was brought to the printer between 1628 and 1651.
