Astronomia
The observatory – which was built specifically to house extra-meridian instruments and long telescopes - was located in a tower with eight windows, its sides facing the four cardinal points, and an opening above for observing the zenith. Along with Sisson’s precious instruments, which were mounted in 1741, the Museum also displays numerous nautical instruments, land surveyor instruments, geodesic instruments and an extraordinarily long (eight meters) multi-tubed Campani telescope, perhaps the only of its kind still in existence. Ettore Lelli’s marble and brass sundial (1741) and a stretched-thread sundial from 1726 are particularly noteworthy. Another room displays several astrolabes and some very rare papers
printed in Beijing by Jesuit priests in the early 1600s.
