This section introduces the academic evaluations and historical background of Martin Opitz, a German poetic theorist of the Baroque period, and his work Buch von der Deutschen Poeterey (The Book of German Poetry). As the first German treatise on poetics, this work has received mixed scholarly assessments—ranging from high praise to skepticism regarding its originality and completeness. The chapter traces the evolution of the concept of "poetics" from the ancient Greek ποιητική to the Latin poeterey, noting that Opitz adopted the singular form to emphasize the methodological significance of "composing German poetry"; his object of poetics was limited to rhymed metrical discourse, distinguishing it from prose and other genres. In his 1617 speech Aristarchus, Opitz had already germinated related ideas, criticizing the contemporary German scholarly tendency to neglect the mother tongue in favor of Latin, and advocating the development of a German national poetics through drawing upon classical poetics. The Buch von der Deutschen Poeterey, completed in 1624, systematically standardized the language, meter, and form of German poetry, promoting the classicization of German secular literature and its integration with mainstream European literature. The subsequent analysis will examine how Opitz synthesized Greco-Roman and Renaissance poetic theories to construct a system of German vernacular poetics from three aspects: the essence, function, and creation of poetry.

I. The Essence of Poetry: From Imitation of Action to Imitation of Nature

This section explores the creative intentions and core poetic theories in Opitz's Buch von der Deutschen Poeterey. Opitz's purposes comprised three levels: responding to the era's call for a reliable German treatise on poetics, since previous metrical reform attempts by Lobwasser, Gesner, and others had failed to produce lasting impact, and only with Opitz's treatise did the standardization of German poetics achieve a breakthrough; elevating the status of poetics and the threshold for poetic creation, criticizing mediocre poets who "pollute noble paper with unregulated rhymes" and discouraging unserious creative attitudes; and calling upon talented and learned individuals to jointly participate in the German vernacular poetic enterprise, frankly acknowledging his own limited abilities and anticipating assistance from others. In terms of theoretical sources, Opitz mentioned four scholars—Aristotle, Horace, Vida, and Scaliger—considering their theories already sufficiently comprehensive, hence shifting his focus to the specific rules of German poetry.

Regarding the essence of poetry, Opitz proposed the core thesis of imitation based on erudition. On the level of erudition, he cited Solon, Pythagoras, Socrates, Cicero, and other ancient sages to demonstrate that poets must possess broad learning rather than merely mastering meter, positioning poetics as a discipline that "incorporates all other arts and sciences." Drawing upon the special meaning of poeta in the humanist tradition, he made it synonymous with the learned humanist, even including Empedocles's natural philosophical writings within the scope of poetry—a view that stands in sharp contrast to Aristotle's exclusion of Empedocles from the ranks of poets. On the level of imitation, Opitz ostensibly adopted Aristotle's formulation that "poetics is nothing but the imitation of nature," yet in fact made a crucial transformation: whereas Aristotle took action as the object of imitation, attaching ethical qualities to action and emphasizing that poetry describes "what might happen," Opitz—departing from his teacher Heinsius's main thesis—shifted the object of imitation from action to nature. Yet this "nature" was not the natural world, but rather shocking events such as Hercules killing his children, Dido's suicide, the burning of cities, and raging plagues. This transformation was closely related to seventeenth-century Neostoicism: the tragic effect was directed toward the subject's self-preservation—through constant viewing of others' sufferings, the audience could psychologically rehearse pain, reduce fear, and better endure real misfortunes. His concept of tragedy was essentially a Neostoic poetic practice that achieved ataraxia through the display of external calamities.

II. The Function of Poetry: The Distinction Between Pleasure and Profit

This section traces the evolution of poetic function from ancient Greece to seventeenth-century Germany, analyzing the complex relationship between pleasure and profit in different theorists. Aristotle emphasized that poetry produces a special pleasure through the truthfulness of imitation, arousing pity and fear—neither mere entertainment nor moral didacticism. Horace proposed prodesse et delectare (to profit and to please), advocating equal weight for educational and entertaining functions while pursuing truthfulness within fiction. Scaliger degraded entertainment to a means and elevated education to an end. Opitz inherited Horace's formulation but leaned toward Scaliger's didactic stance, criticizing contemporary poets for excessive pursuit of pleasing readers, and citing Strabo to emphasize the educational tradition of poetry as ancient philosophy. Confronting the reality of the low status of German poets in the seventeenth century, Opitz refuted Plato's theory of divine madness, redefining the poet as a learned sage synthesizing history, rhetoric, and ethics; in his Trost-Gedichte in Widerwärtigkeit des Krieges (Consolation Poems in the Adversity of War), he educated the populace with Neostoic fortitude and rationality, closely integrating poetic function with the construction of German national poetics and specific historical contexts.

III. The Creation of Poetry: The Debate Between Art and Genius

This section examines Opitz's redefinition of the relationship between "art" (ars) and "genius" (ingenium) in the Buch von der Deutschen Poeterey, responding to the crisis of legitimacy in German poetics. Early modern German humanists faced the dual dilemma bequeathed by Tacitus: the lack of written education among the Germanic peoples intensified cultural discrimination, while the record of ancient songs endowed them with indigenous tradition. To reconcile this contradiction, humanists distinguished ancient songs from elevated poetics representing "art." Opitz realized that merely tracing indigenous traditions could not compensate for German poetics' deficiencies in "art" and "profit"; thus taking Scaliger's Poetices Libri Septem (Seven Books of Poetics) as his theoretical foundation, yet not following Scaliger's assertion that "art outweighs genius"—for according to this theory, German poetry lacking mature forms would be deemed inferior. In his 1617 speech, although Opitz invoked Tacitus's authority to trace indigenous poetic traditions, he considered ancient texts unsuitable as contemporary models. To prevent pioneering attempts from being regarded as expedient measures, he emphasized the dominant position of genius to confer legitimacy upon German poetry. In the Buch von der Deutschen Poeterey, Opitz inherited Plato's theory of inspiration, stating that poetic creation derives from divine inspiration rather than rational art; simultaneously redefining the source of rules, he established the historical logic that "poetry precedes poetics," implying that contemporary German poets' creations could become future rules. He secularized inspiration as the combination of "being filled with sacred imagination" and personal character, and reiterated in his conclusion: technique can be learned, but immortality can only stem from genius; poets lacking divine inspiration remain merely at the level of craftsmen.

IV. Concluding Remarks: From Vernacular Popularization to Cultural Nation

This section interprets Opitz's Buch von der Deutschen Poeterey from three dimensions: the essence, function, and creation of poetry. In terms of essence, Opitz defined poetry as the display of shocking events, distinguishing it from Aristotle's representation of action; in terms of function, he followed Horace and Scaliger's educational view, using Neostoic didacticism to instruct his Silesian compatriots; in terms of creation theory, he invoked Plato's theory of genius to establish for German vernacular poetry a legitimacy transcending formal rules. This work initiated vernacular poetic reform: between 1624 and 1730, fifty-seven treatises on poetics were produced in German-speaking regions. Opitz's promotion of vernacular creation carried dual significance: at the poetic level, elevating the status of the mother tongue; at the political level, in a context of confessional division and intensifying territorialism, paving the way for German political unification through the path of a cultural nation. He advocated learning from classical Latin models rather than following modern Latin compositions, prompting the transformation of poetic language from Latin to the vernacular. By the eighteenth century, German finally stood alongside Latin, and Opitz's vision became reality.
