The end of Oedipus at
Colonus basically sets up the next play in the series, Antigone. The play ends with the Chorus approving of Antigone’s and
Ismene’s decision to go back to Thebes to try to sort out the fight between
their brothers: “For in every way, these things are sanctioned” (1779).
The family has been plagued by lawlessness, whether it was
intentional or not, so the fact that the Chorus says that the girls’ action is
“sanctioned” means they’re finally on the right side of the law. It’s about
time, if you ask us.
