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). A superb sea chart of the Aegean Sea illustrating the whole of Greece and Crete. This example is from the third part of ‘De Nieuwe Groote Lichtende Zee-Fakkel’ dated 1724 which covered the Mediterranean Sea.
