Ritter's Circular Sundial World Map
"[Untitled - World]", Ritter, Franz
Period: 1613 (circa)
Color: Black & White
9 x 9 inches
22.9 x 22.9 cm
This scarce and extremely unique map shows the world projected from the North Pole as if it were the table of a sundial. The landmasses are drawn to scale in proportion to their distance from the pole. The result is a very distorted, though mathematically correct, projection. The river systems in South America and Africa are quite enlarged, with the source of the Nile depicted as twin lakes south of the equator. The cartography in the South Pacific is quite conjectural, with a landmass south of Iava Maior with the coastal name of Beach regnum, and an enlarged Nova Guinea attached to another large landmass.
