Joan Vinckeboons (circa 1616–70) was a Dutch cartographer and engraver born into a family of artists of Flemish origin. He was in the employ of the Dutch West India Company and for more than 30 years produced maps for use by Dutch mercantile and military shipping. He was a business partner of Joan Blaeu, one of the most important map and atlas publishers of the day. Vinckeboons drew a series of 200 manuscript maps that were used in the production of atlases, including Blaeu’s Atlas Major. This circa 1639 map shows the Caribbean islands of Hispaniola (present-day Haiti and the Dominican Republic) and Puerto Rico. The map includes coastlines, coastal features, navigational hazards, settlements, administrative districts, streams, pictorial representation of relief, and rhumb lines for navigation. Geographic names appear either in Spanish or Dutch. The map was once part of a manuscript atlas belonging to the Dutch firm of Gerard Hulst van Keulen, which published sea atlases and pilots for over two centuries. With the demise of the firm, the atlas was acquired and broken up by the Amsterdam book dealer Frederik Muller, who in 1887 sold 13 maps from the atlas attributed to Vinckeboons to the collector and bibliographer Henry Harrisse. The map is part of the Henry Harrisse Collection in the Library of Congress.
