This is a very curious folio sheet with four separate maps of the continents (each measuring approximately 7.7 x 6"). Each map identifies the different countries and linguistic divisions. Each contains tables displaying their script, alphabets and spoken languages. This is an important map in the history of thematic mapping and one of the first to use color to distinguish areas and subjects on a theme. The map of Africa uses color to show the areas of descendents of Ham, Japheth and Shem. The American map depicts CALIFORNIA AS AN ISLAND, and oddly includes what appears to be Persian and Indian alphabets. Nice impression and original color. One tiny hole in margin, else fine.
