What are examples of dramatic irony in Antigone, particularly from the beginning of the play?

Dramatic irony occurs when a character in the play speaks
in a manner that indicates he or she is unaware of other circumstances of which the
audience is aware. In Scene 3 of Sophocles's Antigone, King Creon
speaks to his son Haemon, who is engaged to Antigone, telling
him,

Therefore, rulers must be
supported,
and we must not yield to women.
It would be better, if it had to
be,
to fall at a man's hands and not to be called
worse than a
woman.
(687-691)

The
audience knows that Antigone has buried her brother and that Creon will probably be
defeated by her determination because she obeys the law of
god.

Another example of dramatic irony occurs in one of the
final scenes as the blind prophet Teiresias predicts the ruin of Thebes. But Creon
retorts,

But,
the cleverest
of mortals, old Tiresias, fall with shameful
crash,
when they decorate shameful words
for the sake of profit.
(1051-1054)

Unfortunately for
Creon, he is unaware that he is describing himself; for, he suffers a tragic fall in the
end as he realizes that his prideful actions against Antigone have precipitated the
deaths of his son and
wife.
