Chart divider - Brass - 2000-2010

Unobtainable limited reproduction (280 copies) of the famous Galileo’s military compass from the Museum of the History of Science in Florence. This compass was created specifically in collaboration with the Italian Military Geographical Institute for members of the EUREF Symposium 2009.
The box (30.5 x 22 cm) contains the compass (26 x 5 cm, 4 mm thick), the goniometer (17 cm; 5 mm thick), the foot screws and plumb, all brass. This compass, made of thick brass, is quite heavy (735 g).
The size and engravings are exact copies of Galileo's compass and were made using a diamond-tipped engraver.
The box contains an illustrated book (60 pages) in Italian and English with the story of Galileo's compass, with reproductions of original drawings, plus an interesting CD with various multimedia simulations for use of the compass.
To know more about it, I suggest you see here the notable site of the Museum of History of Science in Florence, then the simulation, then the enrolled operations along the rules of the compass; the same simulations are included on the CD inside the box.
