He published his first maps, of France and Italy, in 1616. By about 1623, Janssonius had begun acquiring bookstores in several European cities, including
Frankfurt am Main,
Danzig,
Stockholm,
Copenhagen,
Berlin,
Königsberg,
Geneva and
Lyon. These bookshops operated alongside his publishing activities and provided outlets for the distribution of his maps and atlases. Additional volumes were issued as the series grew. These included works devoted to maritime geography, the ancient world, and collections of city views and plans. One of these was the
Atlas Maritimus, a maritime atlas published in 1657. Janssonius also issued an extensive atlas of city plans, often referred to as a
Townatlas. The final volume of the series was a celestial atlas created by the German-Dutch cartographer
Andreas Cellarius. Published in 1660, it formed the eleventh volume of
Atlas Major. == Death ==
