concept, Schöner explained in another of his writings, the Opusculum Geographicum (cap.xx): “the Genoese Columbus and Americo Vespucci reaching only the coastal parts of those lands from Spain across the Western Ocean, considered them to be an island which they called America”. Or, as Nicolaus Copernicus put it in De Revolutionibus (lib.I, cap.iii): Ptolemy extended the habitable area halfway around the world, leaving beyond it unknown land, where the moderns have added Cathay and very extensive regions as far as 60 degrees of longitude, so that now a greater longitude of land is inhabited than is left for the Ocean. Moreover, to this should be added the great islands discovered in our time under the Princes of Spain and Portugal, especially America, named after the captain of the ship who discovered it and thought because of its yet hidden size to be another world, besides many other islands heretofore unknown, which we do not wonder to regard as being the Antipodes or Antichthones. Where Schöner departs most conspicuously from Waldseemüller is in his globe's depiction of an Antarctic continent, called by him Brasilie Regio. His continent is based, however tenuously, on the report of an actual voyage: that of the Portuguese merchants Nuno Manuel and Cristóvão de Haro to the River Plate, and related in the Newe Zeytung auss Presillg Landt (“New Tidings from the Land of Brazil”) published in Augsburg in 1514. The Zeytung described the Portuguese voyagers passing through a strait between the southernmost point of America, or Brazil, and a land to the south west, referred to as vndtere Presill or Brasilia inferior. This supposed “strait” was in fact the Rio de la Plata (and/or eventually the San Matias Gulf). By “vndtere Presill”, the Zeytung meant that part of Brazil in the lower latitudes, but Schöner mistook it to mean the land on the southern side of the “strait”, in higher latitudes, and so gave to it the opposite meaning. On this slender foundation he constructed his circum-Antarctic continent to which, for reasons that he does not explain he gave an annular, or ring shape. In the Luculentissima he explained: The Portuguese, thus, sailed around this region, the Brasilie Regio, and discovered the passage very similar to that of our Europe (where we reside) and situated laterally between east and west. From one side the land on the other is visible; and the cape of this region
