Two copper-engraved plates, each 350 x 470 mm, hand-painted, depicting the hemispheres from a polar view. Two climate tables are placed on either side of the northern map; on either side of the southern map, two tables indicate the “value of the degrees of the meridian and those of the parallels in the different latitudes”. An uncommon map taken from the “New Universal Geographical Atlas outlined on the latest observations”, published in Rome from 1792 to 1801. The Calcografia Camerale commissioned the work to replace the “Geographic Mercury”. Giovanni Maria Cassini (1745-1824), a pupil of Piranesi, was a clergyman, geographer, globe maker and cartographer. An excellent example.
