Hessel Gerritsz was the most influential and innovating mapmaker of 17th century and the best informed person, without doubt, in geographical and hydrographical matters in Amsterdam and not only in The Netherlands. In 1627-1628 he compiled a rutter for the Dutch West India Company (WIC). The 1625 loss of Dutch Brazil made clear that the next attempt of the WIC had to be more tenacious and that its commanders needed better information about the areas that had to be seized and could be useful for trade in the West (read: Atlantic). In this book the part of Hessel GerritszÕ handwritten rutter about the Cape Verde Islands (Soute Eylanden) is translated into Dutch, English and Portuguese. The main goal is to unlock this unique and beautiful 17th century Dutch treasure. To remove the veil from the Cape Verde Islands. In a time that information and products floated over the seas with the speed of a sailing ship.
