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). Gerard set about replacing many of his father’s sea charts the first of which was published in 1698. This harbour chart depicts the city of Cette on the French coast of the Mediterranean Sea, now known as the Languedoc-Roussillon port of Sete. It is oriented to the west and bears two inset coastal profiles. The town itself is also depicted in profile. This example is from the third part of ‘De Nieuwe Groote Lichtende Zee-Fakkel’ dated 1724 which covered the Mediterranean Sea.
