Sylvanus's Ptolemy. 1511.
Bernardus Sylvanus Ebolensis, in a new edition of Ptolemy which was issued at Venice in 1511, paid great attention to the changes necessary to make Ptolemy's descriptions correspond to later explorations in the Old World, but less attention to the more important developments of the New World. Nordenskiöld thinks that this condition of Sylvanus's mind shows how little had been the impression yet made at Venice by the discoveries of Columbus and Da Gama. The maps of this Ptolemy are woodcuts, with type let in for the names, which are printed in red, in contrast with the black impressed from the block.
Nordenskiöld gores.
Sylvanus's map is the second engraved map showing the new discoveries, and the earliest of the heart-shaped projections. It has in "Regalis Domus" the earliest allusion to the Cortereal voyage in a printed map. Sylvanus follows Ruysch in making Greenland a part of Asia. The rude map gores of about the same date which Nordenskiöld has brought to the attention of scholars, and which he considers to have been made at Ingolstadt, agree mainly with this map of Sylvanus, and in respect to the western world both of these maps, as well as the Schöner globe of 1515, seem to have been based on much the same material.
