To him the two most important features of tragedy were plot and
character. The plot should contain a change in fortune, preferably
from good to bad, and should ideally hinge on a recognition or
discovery. T
The main character, the protagonist, should be a person in whom
good and bad are mixed but in whom the good predominates. That
definition is usually paraphrased as "a basically noble person with a
tragic flaw," and that flaw, which Aristotle called "harmartia," I think
you can see how Oedipus as a person fits that description. In many
ways he's the ideal man--a caring, proactive, intelligent leader who
gets to work on his country's problem even before he's asked.
However, he also has a quick temper and can't stand to be denied
what he wants. We see that side of him in his conversation with
Teiresias and again in the last scene, when he threatens to torture
the old servant, who is refusing to talk only to protect Oedipus and
his family.
Other characterxs in the play are also well drawn. Creon is basically
level-headed and low-profile, but Oedipus' irrational accusations
drive him to losing his temper. It's one of many ironies in the play
that, at the end, he has reluctantly shouldered the responsibility
that Oedipus has erroneously accused him of wanting. Jocasta, who
sees where the investigation is leading before Oedipus does, shows
us from whom he has inherited his intelligence, just as his account
of his encounter with the man we know was Laius shows from
whom he inherited his temper. Jocasts's first appearance, in which
she prevents a fight between Oedipus and Creon by saying what
amounts to "Oedipus, come inside. Creon, go home" also
foreshadows in a blackly funny way the discovery that will soon be
made about her and Oedipus' true relationship. Teiresias' entrance
