The McGregor Collection has two copies of the atlas: one a 1598 edition and the other a 1603 edition. The two maps together depict the West coast of North America. The coast of upper California runs almost due west until it reaches Cape Mendocino (“C. Medocino”—). Wytfliet represents “Septem civitatem Patria”——the legendary Seven Cities of Cibola—which inspired Francisco Vásquez de Coronado’s expedition in search of gold in 1540-42, as a cluster of cities around a lake which is connected to the Gulf of California by a river. The map designates Cibola (“Cevola”—) as a separate city. On the other map, “Quivira”— appears too far west. Finally, like many other maps of the period, a world map in Wytfliet’s atlas depicts the Straits of Anian connecting to the fabled Northwest Passage from the Atlantic Ocean.
