it seems to me the larger the number, the better it will be. Forests, buildings, etc., may be but roughly marked. If you will give the size and exact location, I will take care that the emblematical figures are properly represented”; and he adds that “in order to make sure that the completed work is well done, I shall let you correct the plates one at a time.” Somewhat later Blaeu writes again that “I shall give especial attention to the engraving of the plates, printing lightly from them at first, in order that changes may be made before the final engraving is done.... Take as much time as you may need, and in case you are unable to finish them during the summer, you may also have the winter.” June 24, 1634, he writes to Schickard: “I have published the first part of my Atlas, containing one hundred and sixty maps, with descriptive text in German, translated from Latin. In the Fall I shall publish the Latin, French and Dutch texts,” these titles being, respectively, “Theatrum Orbis Terrarum,” but dated 1635; “Le théâtre du monde ou nouvel atlas,” but issued in 1634; “Toonneel des Aerdrycx,” 1634. The arrangement and number of maps in the several issues do not agree, but in the main features they are the same. The “Toonneel” may be considered an enlargement of his “Appendix” done in practically the same manner, but with the addition of numerous details, and ornamented with additional illustrations. That he borrowed from the “Nieuwen Atlas” of Joannes Janssonius and Henricus Hondius becomes evident in a comparison of the descriptions of “Germany,” the “Netherlands,” and of certain other parts.
