A fine sea chart showing the Adriatic Sea with detail along the coasts of both Italy and Croatia. Major cities and the best anchorages are noted along with navigational hazards. John Thornton was one of the most important English mapmakers, from the so-called Thames School of chart makers, during the period when Britain dominated mapmaking. In addition to actual chart-making he also was a publisher. He was appointed Hydrographer to the Hudson Bay Company and the East India Company. He collaborated with Fisher, Seller and Mount on many important English atlases including the English Pilot. There are no imprints on this map, but it appears to be from an edition by Mount & Page as it is printed on mid 18th century paper.

Nice impression and slightly toned paper. There is a fold separation at bottom that just enters the map and a couple minor tears in the margins, well away from the map.
