Scarce Dutch sea-chart, showing the Island Menorca with South at the top, which was the primary catalyst for changing the way Menorca was mapped for a number of years.
Van Keulen's chart of Menorca is based upon a manuscript chart prepared by the Van Keulen firm circa 1745. The chart was based upon a detailed study of the island, which resulted in a substantially improved cartographic depiction of the shape of the island, which was followed by other map makers for a number of yers.
This sea chart shows a an extremely detailed treatment of Menorca, oriented with South at the top. The map shows anchorages, soundings, roads, rivers and topographical details, some of which are greatly exaggerated.
The chart was a landmark in the history of the mapping of Menorca and is quite scarce on the market, this being the first example we have ever seen.
