Old color example of the first edition of Mercator's map of Sweden and Norway, one of the most important and influential maps of Scandinavia published in the 16th Century.
Mercator began with the basic cartographic information form his 15 sheet map of Europe published in 1554 and his even larger map of Europe published in 1572 for the basic geographical foundation for the map. In this new map of Scandinavia, Mercator corrects the shape of the Peninsula, making it the foundation map for most maps issued thereafter. While Oretlius had issued a regional map that included Scandinavia, Mercator's map is both more accurate and more focused on the region. For the next several decades, Mercator's map became the most accurate and detailed map of the region to appear in a commercial atlas.
