A rare separately issued example of Jansson's map of Iceland, with no textg on verso, a blank title cartouche, two clearly re-engraved compass roses and obvious, although subtle differences in the engraved names on the map. This map was bound into a contemporary book, with the remnants of the stub margin where it was bound and otherwise narrow margins. A stunning map, including and erupting volcano, sea monsters, sailing ships, decorative cartouches and the spectacular landscape of Iceland. Carolius used Mercator's version of Bishop Gudbrandur Thorlaksson's map as his source. The map was first issued by Hondius in 1629, then re-issued by Jansson and Blaeu the following year, with changes. Non-Atlas versions of the map are quite rare.
Jan Janssonius (also known as Johann or Jan Jansson or Janszoon) (1588-1664) was a renowned geographer and publisher of the seventeenth century, when the Dutch dominated map publishing in Europe. Born in Arnhem, Jan was first exposed to the trade via his father, who was also a bookseller and publisher. In 1612, Jan married the daughter of Jodocus Hondius, who was also a prominent mapmaker and seller. Jonssonius’ first maps date from 1616.
In the 1630s, Janssonius worked with his brother-in-law, Henricus Hondius. Their most successful venture was to reissue the Mercator-Hondius atlas. Jodocus Hondius had acquired the plates to the Mercator atlas, first published in 1595, and added 36 additional maps. After Hondius died in 1612, Henricus took over publication; Janssonius joined the venture in 1633. Eventually, the atlas was renamed the Atlas Novus and then the Atlas Major, by which time it had expanded to eleven volumes. Janssonius is also well known for his volume of English county maps, published in 1646.
Janssonius died in Amsterdam in 1664. His son-in-law, Johannes van Waesbergen, took over his business. Eventually, many of Janssonius’ plates were sold to Gerard Valck and Pieter Schenk, who added their names and continued to reissue the maps.
