Cartography

Celestial sphere made by the Charles-François Delamarche company of Paris in 1805, with coloured engravings on paper on cardboard and coloured engravings on paper on wood, metal and polychrome wood. The sphere bears the inscription “Globe celeste dont la position des Etoiles est reduite a l’année 1800 par M. Messiers astronome de la Marine, de l’Acadèmie Rle des Sciences Ec. Ec.”

The constellations can be seen with their names and corresponding classical figures in colour. The upper half has a horizontal ring with the hours marked in Roman numerals and a brass needle. The sphere is divided into 12 lunes, and the equator and the elliptical are graded. The sphere also has a 7-cm wooden horizon with coloured engravings on paper and the edges painted red. This ring is decorated with the symbols of the zodiac, the months of the year and the directions of the winds, with double grading and a difference in degrees. The tropics of Cancer and Capricorn are only present as lines.
