This group of writers argue that the maps are not necessarily literal records of voyages of exploration. On the 1543 world chart of Guillaume Brouscon this feature, the northern part of "TERRE OSTRALE" (Terra Australis), is called "terre de lucac" (Locach); on this chart, "la Jave grande " refers to Java, and "Jave" refers to an island to its east (Bali, Lombok or Sumbawa). Similarly, on the 1570 "Carte cosmographique ou Universelle description du monde" of Jean Cossin, an originator of the sinusoidal projection, this feature is called "Terre de lucac", as it is also by Jacques de Vaulx on his chart. On the so-called Pasterot atlas (British Library MS Egerton 1513) it is called "IOCAT", another form of Locach.
