Historia ecclesiastica (1544) and ended with Appian (1551). The last was completed after Estienne's departure from Paris by his brother Charles and appeared under Charles's name. Estienne also printed numerous editions of Latin classics, of which the folio Virgil of 1532 is the most noteworthy. He printed a large number of Latin grammars and other educational works, many of which were written by Mathurin Cordier, his friend and co-worker in the cause of humanism. He was trained as a punchcutter, but no font has been identified as his. Estienne did, however, oversee the work of the best punchcutters of the time such as Claude Garamond and Guillaume Le Bé. Under Estienne, Garamond designed the Greek type used by the King of France which was used to print the first edition of Roman History. Consequently, Estienne was the first printer granted permission to use the grecs du roi or Greek types of the king. In the 1530s Estienne's printing represents the first use of apostrophes and grave and acute accents in France. Moreover, Estienne was known as one of the printers responsible for adapting the Aldine roman type in France. Dictionaries One of the best printers of his time, Robert Estienne was asked to either compile a dictionary from the best Latin authors or make one himself; in 1531 he published Thesaurus linguae latinae, which is considered by some scholars to be the foundation of modern Latin lexicography. Moreover, this dictionary made Estienne the "father of French lexicography". He had worked on it for two years, with the assistance only of Thierry of Beauvais. It was 964 pages and was improved in 1536 and 1543 in three volumes. Considered his "greatest monument of Latin scholarship", he employed research assistants for the 1543 version: Andreas Gruntleus, Gerardus Clericus, and Adam Nodius. From his work on the Thesaurus linguae latinae, he published Dictionarium latino-gallicum in 1538 and Dictionaire francoislatin in 1540. These dictionaries were superior to others at the time because non-classical elements had been edited out; when determining words, they were checked for correctness and applicability in context; and citations were exclusively from classical authors. Furthermore, it applied consistency to word order since lexicographers disagreed about whether words should be ordered alphabetically or etymologically. Estienne's thesaurus was alphabetical based on the first three letters of the word, then grouped etymologically. In the 1540s, he began publishing more concise school dictionaries. Many of
