Robert Arnauld d’Andilly (28 May 1589 – 27 September 1674, abbaye de Port-Royal-des-Champs)^[1] was a French conseiller d’État, specialising in financial questions, in the court of Marie de' Medici. By the elegance of his language, he was among the major poets, writers and translators of 17th century French classicism. A fervent Catholic, he played an important role in the history of Jansenism and was one of the Solitaires of Port-Royal-des-Champs. He was also renowned for his part in the development of the pruning of fruit trees, to which he was devoted.
