In 1545, the German mathematician and cartographer Caspar Vopel (1511-1561) designed a famous and influential map of the world, A New Complete and Universal Description of the Whole World, that depicts Asia and America overlapping on the same landmass. Using an interactive, high-definition interface, Amerasia explores the map’s content. Blue pins indicate translated cartouches, pink pins offer short entries on sites with particular Amerasian significance, and yellow pins offer extended essays on Amerasian themes.
