Old-coloured sea chart, heightened with gold, from Volume 1 of Johannes van Keulen’s atlas of sea charts entitled “De Nieuwe Groote Lichtende Zee-Fackel” first published in Amsterdam in 1680. The atlas proved to be very popular and continued to be published throughout the 18th century, during which time it was expanded to six volumes by his heirs including Gerard, Johannes II and Gerard Hulst. This chart, which maps the Bay of Biscay, covers the area from the small town of Finisterre on the northwest coast Spain eastward to the Basque country and onward to the west coast of France, ending at Ouessant Island off the western tip of Brittany. The chart is decorated with a title cartouche surrounded by putti, sailing ships, a naval battle, a compass rose and the French royal coat of arms. Blank verso. Other than some minor discolouration, a finely coloured example in very good condition. 50.5 cm x 58.5 cm
