Of what element does the chorus consistently remind the audience in the choric odes of Sophocles' Oedipus Rex?

Although
theoften speaks situationally, and there is significant variety in the choral odes ofby , it can
be argued that the two most important themes, and ones that are related to each other, are the
power of fate and the necessity of reverence for the gods and their divine laws. Typically,
thestates:

 

... those laws engendered
in the heavenly skies,
whose only father is Olympus.
They were not born from
mortal men,
nor will they sleep and be forgotten.

 

No matter how wise and powerfulis as an individual, he is merely a
mortal, and thus not exempt from fate or divine law. Thus no matter what he does, he cannot
escape the curse on his house. The chorus serves to remind both Oedipus and the audience of
this, and thus emphasizes the role of fate in the plot.
