A photographic facsimile (reduced) of a page from Mulier's edition (1617) as "corrected" according to the Monitum of the Congregations in 1620. The first writer merely underlined the passage with marginal comment that this was to he deleted by ecclesiastical order. The second writer scratched out the passage and refered to the second volume of Riccioli's Almagestum Novum for the text of the order. The earlier writer was probably the librarian of the Florentine convent from which this book came, and wrote this soon after 1620. The later writer did his work after 1651, when Riccioli's book was published. This copy of the De Revolutionibus is now in the Dartmouth College Library.
