Mare Californiae -- The California Sea
Detailed map of America, from Lotter's Atlas Geographicus Portabilis.
The map is perhaps most notable for its unusual naming of the coastal waters off the West Coast of North America as the Mare Californiae.
Shows continuous land bridge from Northwest Coast of America to Asia. The Great Lakes are quite unusual, as is the "Pais de Moozemleck," the remnants of a treatment of the region when California was still mapped as an Island.
Tobias Conrad Lotter (1717-1777) is one of the best-known German mapmakers of the eighteenth century. He engraved many of the maps published by Matthaus Seutter, to whose daughter Lotter was married. He took over Seutter’s business in 1756. Lotter’s son, M. A. Lotter, succeeded his father in the business.
