It has a diameter of 25.6 cm. In an oval cartouch one finds the inscription “Nova et integra universi orbis descriptio. Rothomagi.” “A new and complete description of the world. Rouen.” Below the last line there appears to be space left for the insertion of the author’s name, a thought suggested by the arrangement for the inscription, and underneath the cartouch is engraved a representation of Neptune driving his sea horses and chariot and armed with a trident. There are numerous vessels represented on the globe, sailing the seas, in the style of the sixteenth century. The prime meridian passes through the Canary Islands. The author seems to have drawn largely from Spanish sources, but to some extent from the Portuguese. The outlines of the several countries of the Old World are not particularly well drawn, and it does not appear that the author thought of making an especial point of accuracy. Africa has the outlines of the maps of the sixteenth century, but with an indifference to details. The Senegal and the Niger are made to unite to form the Nile. Asia is not particularly well drawn. Below the island of Cipango the author has engraved the following legend, “Hoc loco secuti sumus recentiores hanc partem verius a continente separantes.” “In this place we have followed the most recent (observers) who rightly separate this part from the continent.” The western coast of America gives evidence of a want of detailed knowledge. Here we read “Haec littora nondum cognita,” “this coast is not yet known,” and below this, “Novus orbis,” and “Hispania major a Nuño Gusmano devicta anno 1539,” “Greater Spain conquered by Nuño Gusman in the year 1539.” California is represented as a peninsula and not an island as on so many of the maps of the closing years of the sixteenth century. The nomenclature along the coast of Mexico is exceedingly rich. Pizarro’s conquest is referred to, but Chili is unknown, “Ulterius incognitum.” The estuary of La Plata is represented as very large. The coast names north of Florida seem to have been obtained from the Verrazano sources of 1524. In the region of Newfoundland, which is represented as a region of numerous small islands, we find “Baccalearum regio,” “Gamas,” “insule Corteralis,” “terro de laborador.” The strait separating Greenland from the mainland is referred to as “Fretum arcticum per quod Lusitani in orientem et ad Indos et Molucas navigare conati sunt,” “Arctic strait through which the Portuguese attempted to sail to the east and to the Indies and the Moluccas,” an allusion to the unhappy results of the Cortereal expedition. Along the coast of the strait which forms the northern boundary of North America we read “Terra per Britannos inventa,” “Land discovered by the British.” A very curious legend along the east coast of Greenland reads “Quii populi ad quos Joañes Scovus Danus pervenit anno 1476,” “These are the people to whom the Dane John Scovus came in the year 1476.” Humboldt was one of the
