All art, in its essence, is a form of imitation, or mimesis, differing from other arts in its means, its objects, and its manner. Whether through rhythm, language, or melody, singly or combined, the poet crafts a representation of actions and life itself. Poetry, in this sense, is not merely a recounting of what has happened, but a profound exploration of what *might* happen, guided by the laws of probability and necessity, thus revealing universal truths that history, bound to particulars, cannot.
Among the various forms of poetic imitation - epic, comedy, and dithyrambic poetry - tragedy stands as the highest and most serious art. A tragedy is defined as the imitation of an action that is serious, complete, and of a certain magnitude, presented dramatically rather than narratively, and adorned with rhythmic and harmonious language. Its unique power lies in its capacity, through scenes of pity and fear, to effect a catharsis, a purging or purification of these very emotions in the spectator.
The construction of a tragedy hinges upon six constituent elements, ordered by their importance: plot, character, thought, diction, melody, and spectacle. Of these, plot, or mythos, is paramount, for tragedy is an imitation not of men, but of an action and of life. A well-constructed plot must be a unified whole, possessing a clear beginning, middle, and end, with incidents so arranged that if any one part is removed or displaced, the whole is disrupted.
The most effective plots are those deemed "complex," characterized by both peripeteia, a sudden reversal of fortune, and anagnorisis, a discovery or recognition that shifts a character from ignorance to knowledge. These elements, interwoven by necessity and probability, heighten the tragic pleasure derived from pity and fear. The tragic hero, central to this plot, must be a figure of high standing, neither entirely virtuous nor utterly depraved, whose downfall comes not from vice, but from some error or frailty, known as hamartia. This nuanced portrayal allows the audience to empathize, experiencing fear for one like themselves and pity for undeserved suffering.
Character, the second most important element, reveals the moral qualities of the agents through their actions and choices. Characters should be good, appropriate to their station, lifelike, and consistent throughout the play. Thought refers to what characters say when proving a point or expressing an opinion, while diction concerns the composition of the verses, the choice of words that convey meaning and enhance the serious themes. Melody, often embodied by the chorus, provides emotional rhythm, and spectacle encompasses the visual elements of the stage, though it is considered the least essential to the essence of tragedy.
Furthermore, tragedy is considered artistically superior to epic poetry, as it encompasses all the elements of the epic, including its meter, but adds the dynamic elements of melody and spectacle, and achieves its effect within a more concentrated timeframe. The poet, in crafting such a work, must visualize every scene, ensuring that complication and dénouement are skillfully managed, and that the various elements combine to produce the desired emotional impact. It is through this meticulous artistry that poetry fulfills its unique function: to present actions that evoke profound human experience and understanding.
