Between 1667 and 1773, the County of Oldenburg belonged to Denmark and was ruled directly from Copenhagen. This detailed map of the Skagerrak was reissued by Doncker. Hendrick Doncker (1626-1699) ran his publishing house in Amsterdam for more than 50 years. Other than Goos, Doncker was always keen on the continuous improvement and growth of his collection of nautical charts. Thus, the “Zee-Atlas” continued to grow.
