Barent Langenes map.
Maps showing Newfoundland as an island began to appear around the end of the 16th century. One of these is the "Terra Nova" map which was published around 1602 in a small atlas by Petrus Bertius. It too, includes a long, dotted area which is probably depicting the Grand Banks or possibly the Gulf Stream. It is one of the earliest to depict the Newfoundland area with some accuracy.
