In 1525, appeared the first work published with the individual imprint of Robert, an edition of the _Apuleii Liber de Deo Socratis_, which was followed in 1526 by the _Ciceronis Epistolæ_, without which hardly any publishing list of the time could be begun. Robert adopted as his device a spreading olive tree, with one or more branches broken off, and the motto _Noli altum sapere, sed time_. This appears to be based upon the words in _Romans_ xi. 20, “Be not high-minded, but fear.” Robert’s career was, however, in a sense, a contradiction of his motto. He was high-minded, and he refused to fear, or at least to be fearful. Shortly after his majority, Robert married Petronilla, a daughter of the famous publisher Jodocus Badius, and the co-operation of his wife proved of no little service in the management of the editorial portion of his business, as she was herself a thorough scholar, and could read, write, and speak Latin fluently. The publisher’s household included for many years, in addition to the members of his family circle, a number of his editors and press-correctors. These assistants represented a number of nationalities, and they had, as a convenience, adopted Latin as their common tongue. Through the example of these permanent guests, aided by the facility of the mistress of the house, Latin became the language first of the table and finally of the whole domestic establishment, even the servants and children having gained a sufficient mastery of the idioms. Maittaire mentions that it was a custom of Robert Estienne to hang up in the streets or in the precincts of the University proof-sheets of important works which were passing through his Press, and to offer a reward for every error that might be discovered. The following list of works, selected from among the more important of the publications issued by the second Estienne during the succeeding fifteen years, will serve to give an impression of the character of his undertakings. For the titles in this list I am indebted to Greswell.[9] 1528. Linacer, Thomas, “De Emendata Latini Sermonis Structura,” quarto. Robert printed two later editions in octavo. Linacer was a learned Englishman, physician and ecclesiastic, and a correspondent of Erasmus, through whom probably he became known to Estienne. His death occurred in 1524, and this Paris edition of his most important work could, therefore, not have had the advantage of the author’s supervision. “Justiniani Institutiones,” and “Digestorum seu Pandectarum volumina quinque Biblia utriusque Testamenti Latina, ex veteribus MSS. exemplaribus emendata, fol. cal. Mart.” This was Robert’s first impression of the complete Bible. For its preparation he had made a very comprehensive collation of the existing manuscripts of the Vulgate with the texts heretofore printed.
