One of the Earliest Thematic World Maps

"Die Ebbe und Fluth auff einer Flachen Landt-Karten Furgestelt", Happel, Everard Werner

This is one of the earliest thematic maps of the world. The ocean currents are graphically depicted and although conjectural, the map is the first serious attempt to portray scientific phenomena based on the reported findings of seamen. Four curious tracks, perhaps denoting subterranean tunnels, link the Black and Caspian Seas, the Caspian Sea with the Persian Gulf, the Mediterranean with the Red Sea, and most interestingly the Atlantic with the Pacific through the Isthmus of Panama. The landmasses are marked with the locations of live volcanoes. Noted as scarce by Shirley.
