Jave-La-Grande is not Australia

Abstract

The continent of Jave-la-Grande on the mid-16th century manuscript Dieppe maps has been the subject of much speculation for over two hundred years and has been claimed to provide evidence of an early Portuguese discovery of Australia. Mathematical and navigational arguments used by some writers to transform the outline of Jave-la-Grande into something more closely resembling that of Australia, and seeking to 'correct' its location and scale, have proved unsustainable.
