Copperplate engraving, 350x480 mm, hand-painted. Uncommon map from “Nuovo Atlante Geografico Universale delineato sulle ultime osservazioni,” published in Rome from 1792 until 1801. The Calcografia Camerale commissioned him to produce the work to replace the “Mercurio Geografico.” Giovanni Maria Cassini (1745-1824), a pupil of Piranesi, was a religious man, geographer, globe maker and cartographer. Excellent copy.
