A rare and beautiful mid-17th century sea chart of the Banda Islands in the South Moluccas, the only source of nutmeg and mace in the world up to the end of the 18th century, by the famous Dutch cartographer Jan Jansson often referred to by his Latinized name, Ioan Ioanssonium (1588 – 1664) and published in Amsterdam in the Dutch edition of his five-volume sea atlas Atlantis Majoris Quinta Pars Orbem Maritimum in 1652. The map was engraved by Jan van Loon (c.1611/14 – 1686) of Amsterdam.
Janssonius was born in Arnhem, the son of Jan Janszoon the Elder, a publisher and bookseller. In 1612 he married Elisabeth de Hondt, the daughter of Jodocus Hondius. He produced his first maps in 1616 of France and Italy. In 1623 Janssonius owned a bookstore in Frankfurt am Main, later also in Danzig, Stockholm, Copenhagen, Berlin, Königsberg, Geneva and Lyon. Elisabeth Hondius died in 1627 and he remarried Elisabeth Carlier in 1629. In the 1630s he formed a partnership with his brother in law Henricus Hondius, and together they published atlases as Mercator/Hondius/Janssonius.
Under the leadership of Janssonius the Hondius Atlas was steadily enlarged. Renamed Atlas Novus, it had three volumes in 1638, one fully dedicated to Italy. In 1646, a fourth volume came out with "English County Maps", a year after a similar issue by Joan Blaeu. Janssonius' maps are similar to those of Blaeu, and he is often accused of copying from his rival, but many of his maps predate those of Blaeu and/or covered different regions. By 1660, at which point the atlas bore the appropriate name "Atlas Major", there were 11 volumes, containing the work of about a hundred credited authors and engravers. It included a description of "most of the cities of the world" (Townatlas), of the waterworld (Atlas Maritimus in 33 maps), and of the Ancient World (60 maps). The eleventh volume was the Atlas of the Heavens by Andreas Cellarius. Editions were printed in Dutch, Latin, French, and a few times in German.
After Janssonius's death, the publishing company was continued by his son-in law, Johannes van Waesbergen. The London bookseller Moses Pitt attempted publication of the Atlas Major in English, but ran out of resources after the fourth volume in 1683
