In the beginning of the 18th century Pieter van der Aa published a large collection of travel stories, including Dithmar Blefken's account of his trip to Iceland. It is accompanied by a map of Iceland by van der Aa.
The shape of Iceland on the map is rather unsightly. The spelling of the place-names suggests that the model was the Ortelius version of the map by Gudbrandur Thorláksson but probably with some elements added from older French maps of Iceland.
