Joan Blaeu’s magnificent ‘Atlas Novus’ included only one map devoted to Norway which was first introduced in 1640. It was not until 1662 that he introduced no less than eight new maps of the country. This map displays the region of Oslo and is arguably the most desirable. The map bearing Latin text is identified as being after the work of Laurids Clausen Scavenius (1562-1626) the Bishop of Stavanger and a geographer. Van der Krogt, P. (Atlantes) 1310:2; Ginsberg, W.B.
