In this the final state of the van Keulen family map of the Pacific Ocean, previously issued under the title 'Pascaert vande Zuyd Zee en een gedeelte van Brazil', Carpentaria island, and several other smaller ones, appear. "Simon Dewez speculated that the apparently retrograde step of the Carpentaria island comes from the confusion of the time on the east coast of Australia. By 1730 some French mapmakers had linked Cape York to the New Hebrides and thence Tasmania. Perhaps being more careful, van Keulen thought the New Hebrides were close enough to be joined to Cape York, but not Tasmania(!)".

The mapmaker
The van Keulen cartographic dynasty continued for nearly two centuries. Johannes van Keulen (1654-1715) had established a bookselling and instrument making business in Amsterdam in 1678, and his son, Gerard (1678–1726), produced new editions of his father's works and made numerous manuscript charts. He was appointed hydrographer to the Dutch East India Company (VOC) in 1706. Johannes's grandson, Jan II van Keulen (1704–1770) took over the business in 1726, and published a new edition of the Asian volume of the 'Zee-Atlas'. He was appointed chartmaker to the VOC in 1743, setting an official seal on a well-established relationship that was to last until the company dissolved in 1799.
