There too he probably met Jacques Peletier du Mans, who had published a translation of the Ars poetica of Horace, with a preface in which much of the programme advocated later by the Pleiade is to be found in outline.
In concert with the Giunta, he now edited an extensive collection of Italian letters, and in 1576 he published his commentary upon the Ars poetica of Horace.
He prepared editions, which won the praise of Edward Gibbon,' of the Ars poetica and Epistola ad Pisones (1749), and the Epistola ad Augustum (1751) of Horace.
