Fine, matched pair of hemisphere maps. The Western Hemisphere shows California as an island, a single Great Lake, and an expansive northwest coastline in North America. A notation describes Thomas Button's search for a Northwest Passage. In South America, there is a small Lake Parime in Guiana, and both the Amazon and Rio de la Plata flow from the large interior Lago de los Xarayes. In the Eastern Hemisphere, the large mythical southern continent fills the bottom of the map and the Dutch discoveries in Australia are not shown. Both hemispheres are enclosed in concentric circles giving compass points, notations and tables, and each is embellished with a beautiful cartouche featuring the female representations of the continents. These two hemisphere maps first appeared in 1639, printed on a single sheet as a double hemisphere map. In this addition, not noted by Shirley, each hemisphere is printed on a separate sheet.
