 "Pentan" is the island of Bintan, and Malaiur was the old Tamil name for the Sumatran city of Jambi (and is the origin of the national name Malay).Robert J.King has suggested that Alfonse's description of "La Grande Jave" could also fit the "Regio Patalis" promontory on Oronce Fine's world map, and indicates that the Dieppe Maps appear to have conflated Marco Polo's Greater Java with Fine's "Regio Patalis" and "Brasielie Regio".
