The finest and most comprehensive baroque atlas was Joan Blaeu's exceptional Atlas Maior, completed in 1665. The original 11-volume Latin edition, containing 594 maps, put Blaeu ahead of his staunch competitor, mapmaker Johannes Janssonius, whose rivalry inspired Blaeu to produce a grandiose edition of the largest and most complete atlas to date. Covering Arctica, Europe, Africa, Asia, and America, Blaeu's Atlas Maior was a remarkable achievement and remains to this day one of history's finest examples of mapmaking.
