One year after her husband's death, Anne Seile instructed the engraver Robert Vaughan to engrave a set of maps of the continents similar to those engraved by her husband for Peter Heylin's 'Cosmographie' in 1652. Siele then issued a third edition of the 'Cosmographie' containing these maps, which have minor geographical revisions, as well as new decorative embellishments.

California is shown as an island, with the Straits of Annian, at which the coastline terminates. Cape Mendocino is shown below the islands St. Clement and Catalina.
