We are passionate about all phases of cartography in its broadest sense. We are fascinated by the potential of remote sensing, GIS, and the tools for today’s digital mapmaking. Yet we love the art and history embodied in antique maps. Understanding man’s continuing change in perception of his environment and world is part of the fun of viewing old maps. And we never fail to delight in the curious forms that maps have taken over the centuries.

When you’re ready to be part of a great group of map-loving people of varied backgrounds, please come to one of our meetings as our guest or join our society now.

Very Curious Map of the Southern Sea

Richly decorated, finely engraved and extensively annotated, this large work is perhaps the most spectacular map of the Americas ever published. It originally appeared in 1719 in the sixth volume of Châtelain's Atlas Historique ou Nouvelle Introduction à l'histoire à la Chronologie et à la Géographe Ancienne et Moderne. (The seven volumes of this historical atlas were issued over fifteen years, from 1705 through 1720.) Although the map extends from Asia's Pacific Rim at the left to the western parts of Europe and Africa at the right, its focus is on the Americas.

The map contains a plethora of geographic information. It tracks the routes of a number of great voyages, including the first encounter with the "New World" by Columbus in 1492; the somewhat later and more southerly
