Rhetoric was a central element of German baroque poetics of the 17th-century.Inheriting the classical and humanist traditions,baroque rhetoric extends beyond to the rhe-torical tropes and figures at the semantic level to encompass a system of principles developed from the practice of written text and oratory.Classical rhetoric in terms of its production and categorization(litigious speeches,political speeches,ceremonial speeches)is closely inter-twined with public life.The baroque political-historical dramas,whether propagating monar-chical virtues,discussing the forms of government,or elucidating the relationship between the reason of state and political ethics,are staged in gymnasiums to facilitate students'language and rhetoric skills and cultivate future leaders in governance through theatre performances,which is mutually compatible with the public nature of classical rhetoric.This paper takes the principles of baroque rhetoric as the theoretical framework,and the three newly translated and published political-historical dramas that are representative of the literary-aesthetic sig-nificance of this epoch as examples.From the macroscopic to the microcosmic level and from historical phenomena back to their intrinsic cause,this paper aims to explore the symbiotic relationship between rhetoric and baroque drama,particularly highlighting how rhetoric influ-ences and prescribes the Baroque drama performances and poetics,and how rhetorical tropes and figures become an effective means to enhance the expressive power of the dramatic lan-guage.
