Answer:
"once the anger of heaven has struck, that house is shaken".
Step-by-step explanation:
In Strophe 1, Chorus remarks "once the anger of heaven has struck, that house is shaken" to portray a family being punished by the gods. By these line, he means that once gods' vengeance befall upon a family, the whole family will be crushed and destroyed.
This metaphor relates to the fact that Creon, who thought that he was all powerful to condemn anyone to death, was in fact not at par with the gods because he pays the price of his actions with the lives of his son and wife. It establishes the fact that humans do not determine the fate of themselves or any other person.
