Galileo participated in exchanges of encrypted correspondence at key moments in his life. In 1610–11, following the publication of the “Sidereal Messenger,” ciphers helped Galileo to diplomatically reveal what he was observing through his telescope. After his Inquisition trial of 1633, Galileo and his closest allies relied on a substitution code (gergo) to protect the privacy of his conversations and to facilitate the removal of his library and manuscripts at Arcetri. Throughout this article, we position Galileo's use of codes within the rich contemporary literature about communicating securely and reflect on cryptic writing as a strategy of communication and dissimulation.

解密伽利略：审判前后的沟通与保密

伽利略在他生命的关键时刻参与了加密通信的交换。1610-11 年，随着“恒星信使”的出版，密码帮助伽利略外交地揭示了他通过望远镜观察到的东西。在 1633 年的宗教裁判所审判之后，伽利略和他最亲密的盟友依靠替代代码（格戈) 以保护他的谈话隐私，并方便他在 Arcetri 的图书馆和手稿被移走。在整篇文章中，我们将伽利略对密码的使用定位在丰富的当代文献中关于安全通信的位置，并将神秘写作作为一种交流和伪装的策略进行反思。
