The current rare map of the North Atlantic is a scarce example of Heydt’s cartographic artistry dating from the mid 18th century.  It includes the coasts of Québec, Nova Scotia, Newfoundland and Labrador, Greenland, Iceland, Scandinavia as well as the coast of North-Western Europe.  The rare map depicts hunting scenes as well as sailing ships, marine life/sea monsters, multiple European coat of arms, and a beautiful wind rose. 
Heydt was an engraver, architect and surveyor hired by the Dutch East India Company (VOC) in the early 1730’s.  He was stationed in the company’s Asian outposts such as Ceylon (Sri Lanka) and Batavia (Jakarta, Indonesia), and returned to Europe in 1741 after resigning from the Company due to ill health.  In Europe, he was hired as an architect and surveyor in the Grand-duchy of Hohenlohe-Schillingsfurst, near Nuremburg.  In 1744 his Allerneuester Geographisch und Topographischer Schau-Platz Africa und Ost-Indien was published by Johann Carl Teschner and the heirs to Johann Baptist Homann.  The work included maps and views of different VOC settlements and outposts.
