Elbe - Weser Seekarte Jacobsz& Lootsman, Jacob & Casparus ca. 1663 River Elbe Nautical Chart Copper Plate This is a early engraving of the entrance to the river Elbe and the surrounding coastline. This chart presents the various islands and relative depths of the entrances to the river. For navigational purposes rhumb lines cross the map from some nineteen points. Two of these points are compass roses pointing to north at the bottom of the map. Three alphabetical keys at the top of the map provide reference to the names of parts of the river and coast. A solitary contemporary ship sails the center of the sea. Comparative measurements in nautical miles are present on the bottom right hand side with the Dutch, Spanish and English standards of the period. The name of the publisher on the map is Iacob Theunifz who published under the name of ‘Lootsman’. Jacobsz & Lootsman and Jacob & Casparus were publishers and chart makers based in Amsterdam. The name ‘Lootsman’ was used to distinguish themselves from their rivals. Reference Tooley's Dictionary of Mapmakers, Early World Press, 2004
