The Unravelling is that which extends from the beginning of the change to the end. The fourth kind is the Simple. For whereas there have hitherto been good poets, each in his own branch, the critics now expect one man to surpass all others in their several lines of excellence. In speaking of a tragedy as the same or different, the best test to take is the plot. Identity exists where the Complication and Unravelling are the same.
Many poets tie the knot well, but unravel it ill.
Both arts, however, should always be mastered. In the Epic poem, owing to its length, each part assumes its proper magnitude. In the drama the result is far from answering to the poet's expectation. Even Agathon has been known to fail from this one defect. This effect is produced when the clever rogue, like Sisyphus, is outwitted, or the brave villain defeated.
