The firm of Van Keulen was founded around 1678 by Johannes van Keulen (1654-1715) and in 1680 he published the ‘Zee Atlas’. The multi volume ‘Zee Fakkel’ followed soon after. On his 50th birthday he left the management of the firm to his talented son Gerard (1678-1726). This sea chart orientated to the west extends from the French port of Toulon in the lower right to Alicante in Spain. Barcelona in Catalonia is in the centre of the map. Offshore are the Balearic Islands of Ibiza, Majorca and Minorca. The insets upper right above the ornate title depict the harbours of Marseille, Palma in Majorca and Port Mahon in Minorca. This example is from the third part of ‘De Nieuwe Groote Lichtende Zee-Fakkel’ dated 1724 which covered the Mediterranean Sea.
