The subject of this 17th century Dutch oil painting is a Dutch navigator depicted standing beside table draped in an elaborate Turkish carpet. The figure is believed to be Willem de Vlamingh, a navigator with the Dutch United East India Company. Various objects and instruments can be seen on the table, including a celestial globe, cross staff, astrolabe, dividers and charts. At left, curtains open to reveal a marine scene.
This work has been attributed to Jan and Nicholas Verkolje. It is thought that after the death of Jan Verkolje in 1693, his son Nicholas, an apprentice in Jan's office, completed the work.
