Published in 1761 by Jacques-Nicolas Bellin, official hydrographer to the French Royal Navy, this masterfully detailed chart depicts the strategic Strait of Gibraltar connecting the Atlantic Ocean and the Mediterranean Sea. The chart was produced at the French Dépôt des Cartes et Plans de la Marine under the direction of Etienne-François, Duc de Choiseul, Minister of War and Marine, during the height of the Seven Years' War. The composition features radiating rhumb lines centered on a prominent compass network across the narrow passage between southern Spain ('Espagone') and the Barbary Coast ('Coste de Barbarie'). In addition to coastal soundings and geographical landmarks from Cadiz to Ceuta and Tangier, the chart features an extensive inset titled 'Plan de Gibraltar' depicting the Rock's military fortifications, town layout, and batteries, complete with an indexed key. In the upper-left corner, a detailed tide chart ('Tables des Marées') provides essential hydrographic data for navigating the strait's complex currents. Graphically accented by an ornate rococo draped cartouche at the right, Bellin's map reflects the high watermark of 18th-century French military cartography, balancing artistic elegance with rigorous scientific precision intended for navy ship commanders.
