Christian Sgrooten (c. 1525 - c. 1604) was a Dutch cartographer whose output found its greatest longevity in the copies of his maps made by Abraham Ortelius. Nothing is known of his childhood or training. His first recorded map dates to 1557 (a manuscript map of the woods near Gelderland). He was able, on the strength of this piece, to become royal geographer to Philip II, for whom he began to produce surveys of the Low Countries. He developed a relationship with Hieronymous Cock, who printed a number of his works - which we know only thanks to Ortelius, since only a handful of Cock's editions of Sgrooten are known to survive. Sgrooten would in the 1570s produce a number of maps of the Holy Land and Jerusalem and the Danube; he was commissioned to produce a manuscript atlas for the Duke of Alva in 1568, which was delivered yet unfinished in 1573 and survived in a singlle copy. A second atlas in 1592, also manuscript, was completed. Despite the limited dissemination of his work, Sgrooten was well esteemed by both Ortelius and Mercator; De Jode, too, used Sgrooten's maps as a source for some of his work.
