The second edition was published in 1643, only two years after the first, showing the work's success. It was completely reset, reducing it from around 900 to 800 pages, with every illustration redrawn. Including a number of corrections, it was published in Cologne by Kalckhoven. Kaspar Schott edited the revised third edition of the book (1654), finding and correcting a great many errors in Kircher's original text. It was the first edition in folio format, published in Rome by Blasius Deuersin and Zanobius Masottus.
