Iceland is the most prominent country on the map but we can also see the Faroe Islands, Jan Mayen, and part of Greenland. The island is for the most part drawn after the map in Niels Horrebow's book about Iceland. Bellin has also copied some things from Dutch nautical charts. Nothing points to Bellin having any knowledge of the better version of the Knoff map, the Homanns map of 1761.
