A curated edition presents the poet's correspondence arranged chronologically, incorporating several letters newly recovered and one written on behalf of Cardinal Ippolito d'Este. The letters largely concern his commissariat in Garfagnana and display practical statecraft, administrative detail, and a more candid voice than his courtly verse. A historical‑critical preface reconstructs family background and career, while appended documents, notes, and rare printing privileges illuminate the editorial history of his major poem and provide contextual commentary for readers and scholars.
