[Throughout his scholarly career Justus Lipsius (1547-1606) always entrusted the manuscripts of his works to the Officina Plantiniana; first to its founder, Christopher Plantin, either in Antwerp or in Leiden, then to his oldest son-in-law, Franciscus Raphelengius, Sr., who became Plantin's successor in Leiden, and finally, after Lipsius returned to the Southern Low Countries, to Plantin's second son-in-law, Johannes Moretus, who from the late 1590s on, could count upon the assistance of his son Balthasar. Because all of Plantin's publications were protected by privileges granted by Emperor Maximilian II (1565) and King Henry III of France (1582), he never had to worry about unauthorized editions of his work within these realms. Since Raphelengius continued the press founded by his father-in-law in Leiden, the privileges applied to his publications as well. They ended, however, when Plantin died on I July 1589 and indeed the first German editions of Lipsius's works, printed without his knowledge, were available at the next spring book fair in Frankfurt. Lipsius soon realized that these cheaper and sloppier editions not only threatened his fame as a humanist; he was afraid that works which he never intended to publish might appear as well. As soon as he had settled in Liege after his final farewell to Leiden, he appealed to Emperor Rudolph II. Thanks to the support of influential friends at court, Lipsius was granted his own privilege (I August 1592), valid for thirty years, to be passed to the printer of his choice (in his case always Moretus). What in Plantin's day had been an economic measure had now chiefly become an intellectual one, with added financial guarantees for Moretus thanks to Lipsius's faith. Hardly five years later a similar privilege, using Rudolph's as its model, was granted to him by the Spanish king., Throughout his scholarly career Justus Lipsius (1547-1606) always entrusted the manuscripts of his works to the Officina Plantiniana; first to its founder, Christopher Plantin, either in Antwerp or in Leiden, then to his oldest son-in-law, Franciscus Raphelengius, Sr., who became Plantin's successor in Leiden, and finally, after Lipsius returned to the Southern Low Countries, to Plantin's second son-in-law, Johannes Moretus, who from the late 1590s on, could count upon the assistance of his son Balthasar.
