Up to the early 19th century the Greek seas were practically still uncharted. The French Depot de la Marine was the first to make efforts for the accurate charting of Greek seas since the middle 18th century. Meanwhile, the other naval forces of the time (British, Spanish, Napolitans, Swedish ) followed the French efforts by establishing national hydrographic services and programs of accurate sea charting since the very end of 18th century. Klint Gustaf, Karta ofver Medelhafnet,samt Adriatiska hafnet och Archipelagen, Stocholm, 1820. Impressive 99x69cm, extremely rare early scientific copper engraved Sea chart of the Greek seas, covering the Adriatic, the Ionian, the Aegean and the adjacent Mediterranean areas. Separately printed, but part (number 30) of a Swedish Nautical Atlas that never been completed. The FIRST known Swedish chart of Greece. Also a very accurate and scientifically advanced chart for its time. Gustaf Klint (1771-1840) was a Swedish vice Admiral. In late 18th century, the Swedish navy (following the French efforts) had undertaken the creation of the “Sverige Sjo Atlas”, charting the Baltic & the Mediterranean. Klint was the chief responsible admiral for this project that started its publication in 1797 and continued with separate publications of charts, but never completed. For the Mediterranean part of the project (the current map) the Swedish navy had conducted specific surveys, gathering information that were blended with the French, Spanish and Napolitan survey observations (as the title of the chart suggests). It is a surprisingly accurate chart, presupposing high quality observations & measurements. EXTREMELY RARE
