Western Civilization’s understanding of the size and shape of planet earth can be traced through the maps and atlases that were published three to five  hundred years ago.

Even before Columbus made his first westward voyage, it was generally accepted that the world was round, says map collector Henry Wendt (left). But the size of the globe was thought to be much smaller than it actually is.

The earliest printed maps are not just a record of growing cartographic understanding of the world, explains map collector Henry Wendt. They also document the powerful influence of the Church in the European view and understanding of that world.

The exhibit drawn from Wendt's collection, Envisioning the World: The First Printed Maps 1472-1700, continues through January 17, 2010 at the Sonoma County Museum.
