An original copperplate, engraved map of the EAST RIDING of YORKSHIRE (Ducatus Eboracensis pars Orientalis) by Jan Jansson. First published in Jansson's Atlas Novus in 1646, this map is the 1st edition (verso text in Latin with print register Mmmmm). The map is unframed, unmounted, and has original hand colour. The printed area is approximately 500x370mm and the map has good margins. This is a beautifully engraved and decorative map with an ornate scale (surrounded by three cherub); a title cartouche with figures representing the important agricultural economy of the county; two sailing ships; and rhomb lines in the North Sea. The map includes a wealth of geographical details including rivers, relief, towns, villages, wapontakes and estates. The overall condition of the map is excellent.
