Cartography
Juan de la Cosa made several maps of which the only survivor is the famous map of the world, the Mappa Mundi of 1500. It is the oldest known European cartographic representation of the New World. Of special interest is the outline of Cuba, which Christopher Columbus never believed to be an island. Walkenaer and Alexander von Humboldt were the first to point out the great importance of this chart. It is now in the Museo Naval in Madrid. Reproductions of it were first given by Humboldt in his Atlas géographique et physique.
