Map of the Archbishopdom of Maghdeburgensis and Anhaltinus. Copperplate engraving, non contemporary hand colored. Cartographer: Blaeu. 15" x 19 1/2" Willem Janszoon Blaeu(1571-1638) was a Dutch cartographer, atlas maker, and publisher.  He published the Atlas Novus in 1635.  Appointed Map-maker for the Dutch East India Company in 1633, Willem Blaeu also printed books from the different religions of the time, including Catholic, Protestant, and Jewish Works.  His two sons Joan and Cornelius continued his map-making and publishing business after his death. This map is attributed to Willem Blaeu and was published by Blaeu and son Joan in Atlas Novus in 1635.  It was included by Joan Blaeu in a 1662 reissue of Atlas Novus called Atlas Maior published in 11 volumes in latin with 594 maps.  It was the largest and most expensive book to be published during the seventeenth century.  A complete original of the atlas is housed by the Austrian National Library with a digital version offered by the Regional Archives of Leiden.  A reproduction from this copy was published by Taschenin 2006 with notes by Dr. Peter van der Krogt, of Utrecht University, the leading expert in the field of Dutch cartography. The origin of this map was confirmed in Koeman’s Atlantes Neerlandia—The folio Atlases by Willem Janszoon Blaeu compiled by Dr. Peter van der Krogtof Utrecht University and published in 2000 by HES.
