Abstract John Dastin, a noted alchemist who lived ca.1300, followed the lead of many of his contemporaries and predecessors in using letters to propagate his views on alchemy. This article identifies a number of letters that Dastin wrote, and includes one text addressed to a cardinal of the city of Naples. This letter is virtually a copy of a work by Arnold of Villanova. I believe that other works ascribed to Dastin will also show a great dependence on Arnold's works.

约翰·达斯汀的书信

摘要 约翰·达斯汀 (John Dastin) 是一位生活在公元 1300 年左右的著名炼金术士，效仿他的许多同时代人和前辈，通过书信传播他对炼金术的看法。这篇文章确定了达斯汀写的许多信件，其中包括一封写给那不勒斯市红衣主教的信件。这封信实际上是维拉诺瓦的阿诺德作品的副本。我相信归于达斯汀的其他作品也会表现出对阿诺德作品的极大依赖。
