Description:
This version of a talk by a cartographic historian discusses the European discovery of the Pacific Ocean by Vasco Nunez de Balboa in September 1513 and how a 1507 world map published in Strasbourg appears to show "America North and South as two very large island-continents ... and beyond them lies an ocean stretching some thousands of miles west." Includes image of the 1507 map. From a UK retailer of maps and travel books.
