The present map is a later reprint of Duchetti’s map of the world, published in 1570, with Giovanni Orlandi’s imprint added, and no other changes.

Duchetti’s map is very similar to Forlani's third map of the world, although smaller, and with all four corners now devoted to text. The map on an oval projection, shows North America still joined to Asia, as on Gastaldi’s 1546 map; however, much of the maps southern hemisphere content is taken from Gastaldi’s 1561 wall map.

By 1565, Forlani’s maps of northern North America included the label ‘Nueva Franza’ to recognize the growing French role in exploring what was still a little-known continent. Despite Gastaldi pioneering the idea of separate Asian and American continents with the addition of the Strait of Anian in 1562, Forlani disregards this advance. Many of the eastern coastal features compare well with modern maps; proof that Forlani was skilled at incorporating the latest knowledge about North America's shape from existing charts and explorers' descriptions.  Florida and Cuba, for example, are quite accurately positioned.

Paolo Forlani (fl1560-1574) is unusual within the Laferi school because he was one of the few to combine the talent of mapmaking and engraving, while also infrequently acting as a publisher and mapseller. He was much-sought after as an engraver and mapmaker, particularly as he was adept at the difficult art of engraving lettering. Consequently, he was employed by four of the leading publishers of the period to prepare maps for them -Giovanni Francesco Camocio, Ferando Bertelli and Bolgnini Zaltieri from Venice, and Claudio Duchetti from Rome.

Duchetti was born in France under the name Claude Duchet. He was the nephew of and part successor to Antonio Lafreri's publishing firm upon the latter's death in 1577.

Orlandi (fl1590-1640) is probably best known as a publisher of engravings after the works of Michelangelo and Raphael.
