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). One of a handful of charts with similar title covering the Aegean Sea, an inset upper left depicts Schiro. This one is without the imprint of van Keulen’s and with the plate number ‘XV’. It shows the north eastern portion of the Sea including the Sea of Marmara and the city of Constantinople. It extends along the coast of Turkey to the island of Chios. There are insets above of ‘I. Tenedos en natolia’ and lower right of ‘Oost Kust van Scio’ and ‘De Golff van Smyrna. This example is from the third part of ‘De Nieuwe Groote Lichtende Zee-Fakkel’ dated 1724 which covered the Mediterranean Sea.
