Andre Thevet, La Cosmographie Universelle, 2 vols. (Paris, 1575). In his text (Vol. II, fol. 445v) Thevet refers only in passing to the `terre australe, qui n'est encor comme ie croy descouverte, mais selon mon opinion d'aussi grande estendue que l'Asie ou l'Afrique ...', and Harrison may have been thinking primarily of the map (facing fol. 937v) entitled `Quarte partie du monde', essentially devoted to the Americas, in which `Nouvelle Guinee' is shown as an enormous promontory extending northwards from the `Cercle Antartique' almost to the Equator. Intriguingly, no such land mass appears in the map of Asia (Vol. I, facing fol. 12v), where the islands represented as close to New Guinea in the other map are shown in the open sea, and some way south of the Equator.
