Ferdinand Verbiest
In 1674, Ferdinand Verbiest developed the "Kunyu Quantu", a similar map, but with various improvements. It consists of eight panels, each 179 cm x 54 cm, together displaying two hemispheres in Mercator projection. The two outer scrolls individually depict cartouches that contain several kinds of information on geography and meteorology. The making of Verbiest's "Kunyu Quantu" was intended to meet the interest of the Kangxi Emperor, as Verbiest's introductory dedication implies. There currently are at least fourteen or fifteen copies and editions of this map known in Europe, Japan, Taiwan, America, and Australia.
