Hugo Grotius’s De iure belli ac pacis: A Report on the Worldwide Census of the Sixth Edition (1642, Blaeu)

This article constitutes the sixth instalment in our series on the census and study of the reception of the first nine editions of De iure belli ac pacis. This edition has long held a prominent place in studies and editions of Grotius’s work since it was the last published during his lifetime. The report first outlines the genesis of the edition in the context of Grotius’s relationship with Johann Blaeu (1596–1673) and Cornelius Blaeu (1610–1642), who had recently inherited the Blaeu print firm from their father Willem. It then elucidates a number of crucial ways in which the 1642 edition differed from the five previous editions, especially via the addition of an extensive new series of annotations to ibp and a separate set addressed to the Epistle of Philemon. Finally, it concludes by providing the preliminary results of the census concerning the one hundred and twenty-one copies we have found.
