Bird’s-Eye View of Sloten in Friesland by Nicolaes van Geelkercken, ca. 1616 This captivating hand-colored engraving presents an early 17th-century bird’s-eye view of the fortified Frisian town of Sloten (Sloten, Friesland, The Netherlands), one of the smallest cities in the Netherlands. Titled “Sloten,” this map was drawn by the Dutch cartographer Nicolaes van Geelkercken (1585–1656) and published around 1616 as part of *Rerum Frisicarum Historia* by Ubbo Emmius, a major historical and topographical account of Friesland. Geelkercken's finely detailed and colorful rendering of Sloten reveals the town’s strategic location at the junction of canals and waterways, emphasizing its historical significance in defense and trade. The city is enclosed by a fortified wall with bastions and gates, including clearly labeled entries such as *Smeerk poort*, *Wicker poort*, *Lemster poort*, and *Wolt poort*. The moat and canal systems are navigated by numerous small ships and barges, illustrating the commercial vibrancy of the time. Inside the city walls, the engraving highlights the carefully arranged red-roofed buildings, a central square (*het marckt*), the *Raadhuis* (town hall), and the large church at the heart of the town. Green spaces, orchards, and residential blocks are also illustrated with remarkable clarity for the period. The decorative cartouches—one bearing the city’s coat of arms and the other a Latin dedication to the city council—enhance the map’s aesthetic and historical value. This map is a rare and valuable artifact that reflects both the artistry and the geographic knowledge of the Dutch Golden Age. It offers a historically rich and visually delightful representation of one of Friesland’s most picturesque and historically preserved cities. Condition report: Good overall condition.
