The article focuses on the question of the original language of composition of the De perfecto magisterio, a Latin treatise on alchemy attributed to Rāzī and Aristotle. After studying the arguments in favour of an Arabic origin, the author examines the former arguments in favour of a Latin original composition. Afterwards, he brings a new strong and decisive argument: quotations from the Liber dabessi and its Tabula Smaragdina, a Latin text prior to the De perfecto magisterio.

在 De Perfecto Magisterio 的起源：阿拉伯语或拉丁语作品的翻译？

这篇文章的重点是《完美大师》（De perfecto magisterio）的原始写作语言问题，这是一部属于拉兹和亚里士多德的关于炼金术的拉丁文论文。在研究了支持阿拉伯血统的论点后，作者检查了支持拉丁原创作品的先前论点。之后，他带来了一个新的有力而决定性的论点：引自Liber dabessi及其Tabula Smaragdina，这是De Perfecto magisterio之前的拉丁文本。
