Chapter 11
Classical Aristotle GreekA reversal is a change of the situation into the opposite, as described above, this change being, moreover, as we are saying, probable or inevitable— like the man in the Oedipus who came to cheer Oedipus and rid him of his anxiety about his mother by revealing his parentage and changed the whole situation.
In the Lynceus, too, there is the man led off to execution and Danaus following to kill him, and the result of what had already happened was that the latter was killed and the former escaped.
A discovery, as the term itself implies, is a change from ignorance to knowledge, producing either friendship or hatred in those who are destined for good fortune or ill.
A discovery is most effective when it coincides with reversals, such as that involved by the discovery in the Oedipus.
There are also other forms of discovery, for what we have described may in a sense occur in relation to inanimate and trivial objects, or one may discover whether some one has done something or not.
But the discovery which is most essentially part of the plot and part of the action is of the kind described above, for such a discovery and reversal of fortune will involve either pity or fear, and it is actions such as these which, according to our hypothesis, tragedy represents; and, moreover, misfortune and good fortune are likely to turn upon such incidents.
Now since the discovery is somebody’s discovery, in some scenes one character only is discovered to another, the identity of the other being obvious; but sometimes each must discover the other. Thus Iphigeneia was discovered to Orestes through the sending of the letter, but a separate discovery was needed to make him known to Iphigeneia.
We see then that two elements of the plot, reversal and discovery, turn upon these incidents. A third element is a calamity. Of these three elements we have already described reversal and discovery.
A calamity is a destructive or painful occurrence, such as a death on the stage, acute suffering and wounding and so on.
