Abstract The main purpose of this article is to establish a new critical edition of the anonymous Liber restauracionis et opposionis [Book of Restoration and Opposition] taking into account three manuscripts. Two of them are well-known from earlier historical writing, especially the work of Wolfgang Kaunzner who made the first edition in 1986. The third one is a newly-found manuscript in the Biblioteca Medicea Laurenziana in Florence. We present this copy in detail here. To introduce our edition, we come back to the main arguments which lead us to make the hypothesis that this text is an original Latin adaptation, rather than a possible Arabic–Latin translation of a version/adaptation of al-Khwārizmī's Algebra.

The Liber Restauracionis：新发现的佛罗伦萨中世纪代数副本

摘要 本文的主要目的是考虑到三份手稿，对匿名的 Liber restauracionis et opposionis [恢复与反对之书] 建立一个新的批评版。其中两个因早期历史著作而闻名，特别是沃尔夫冈·考茨纳 (Wolfgang Kaunzner) 的著作，他于 1986 年出版了第一版。第三个是在佛罗伦萨的 Biblioteca Medicea Laurenziana 中新发现的手稿。我们在此详细介绍此副本。为了介绍我们的版本，我们回到主要论点，这些论点导致我们假设该文本是原始拉丁语改编版，而不是可能是花拉子米代数的版本/改编版的阿拉伯语-拉丁语翻译。
