The University of Jena was an important locus for chymistry teaching in Germany throughout the seventeenth century. Zacharias Brendel the Elder and the Younger, Werner Rolfinck, and Georg Wolfgang Wedel were four of the Jena professors who offered courses of chymistry during this time. These four held notably divergent views on the purpose, character, and legitimate content of chymistry, as well as of its proper place within the university. The distinctions among them prove especially clear in their widely differing assessments of metallic transmutation and of other longstanding chymical traditions and pursuits. Significantly, their sequential views do not form any linear progression over time. Instead, they illustrate the continuing disagreements and negotiations about chymistry, its role, and its identity as a discipline. The situation at Jena enriches our understanding of chymistry’s seventeenth-century “didactic tradition” and documents the internal diversity of the subject and of its professors and practitioners.

在整个 17 世纪，耶拿大学是德国糜烂学教学的重要场所。Zacharias Brendel the Elder and the Younger、Werner Rolfinck 和 Georg Wolfgang Wedel 是在此期间提供糜烂学课程的耶拿教授中的四位教授。这四人对 chymistry 的目的、特征和合法内容，以及它在大学中的适当位置持有明显不同的观点。他们之间的区别在他们对金属嬗变和其他长期化学传统和追求的广泛不同的评估中尤其明显。值得注意的是，它们的顺序视图不会随时间形成任何线性进展。相反，它们说明了关于 chymistry、它的作用以及它作为一门学科的身份的持续分歧和谈判。
