8vo, XIII, 140pp. Hardcover with pictorial boards and d/w in excellent condition now protected by clear archival covering, text in pristine condition. This is the story of an enigma which has been unresolved for over four centuries. Maps done in the French School of Navigation in Dieppe circa 1536-1550 portrayed a vast land mass south of Indonesia that many have associated with the Australian continent while others have questioned that concept. The expert cartographer analyses all the evidence and makes a convincing argument in favour of the Portuguese presence. Illustrated in detail with b/w drawings and maps throughout.
