Cartouches, or Decorative Map Titles

Cartouches are the elaborate decorations that frame map titles and other information about the map. They add an artistic or symbolic narrative to the maps they describe. According to map historian Edward Lynam, cartouches that frame titles first appear on Italian maps in the 16th century. They persist on maps until the middle of the 19th century, going through many stylistic changes. Below are selected cartouches from maps in our collection, beginning in 1703 and ending in 1852.
