(1632–1675), who holds a position of great honor among map historians. Several of his paintings illustrate maps hanging on walls or globes standing on tables or cabinets.

and
West Friesland, as he represented it as a wall decoration in three of his paintings. Though no longer extant, the map's existence is known from archival sources and the second edition published by Willem Blaeu in 1621, titled ''Nova et Accurata Totius Hollandiae Westfriesiaeq. Topographia, Descriptore Balthazaro Florentio a Berke
ode Batavo''. Vermeer must have had a copy at his disposal (or the earlier one published by Van Berckenrode). Around 1658 he showed it as a wall decoration in his painting ''
Officer and Laughing Girl'', which depicts a soldier in a large hat sitting with his back to viewer, talking with a smiling girl who holds a glass in her hand. Bright sunlight bathes the girl and the large map on the wall. Vermeer's gift for realism is evidenced by the fact that the wall map, mounted on linen and wooden rods, is identifiable as Blaeu's 1621 map of Holland and West Friesland. He captures faithfully its characteristic design, decoration, and geographic content.
Legacy

His maps formed the bulk of the
Atlas Maior, which became a collector's item in Amsterdam.
