This section is meant to emphasize the evolution of the nautical instruments and cartography throughout time. Together with the antique French charts of the Napoleonic age, there are other exemplars from England, the old Austrio-Hungarian empire and Italy, as well as some prototypes of French pilot's books (portolanos) of the end of the XVIII century and few Italian ones of the XIX century.
The instruments occupy a varied collection of samples: from the Handley's quadrant to the many different makes of sextant, and also marine chronometers, octants, standard (steering) (mariner's) compasses (a secco), of which the most notable is that of "Narcissus", the famous ship immortalized by Conrad, and also other azimuthal devices, such as, among the most remarkable, the Borda's Circle.
Other instruments that may attract people's attention, like the pocket sextant of the Commander and explorer Giacomo Bove, are: a mechanical tide gauge, a sounding line/plummet/bathometer/echo sounder of the "Magnaghi" type, old log chip/log ship, etc.
Between the last acquisitions you can admire the "normal" compass and the automatic pilot of the transatlantic Stockolm, that collided with the Andrea Doria.
