Oedipus’s daughter’s extraordinary negation (8)

I believe the answer is:

antigone

I'm a little stuck... Click here to teach me more about this clue!

'oedipus's daughter's' is the definition.
I can't judge whether this definition defines the answer.

'extraordinary negation' is the wordplay.
'extraordinary' indicates an anagram.
'negation' with letters rearranged gives 'ANTIGONE'.

Can you help me to learn more?

(Other definitions for antigone that I've seen before include "classical play" , "Tragic heroine" , "Jocasta's daughter" , "Greek play" , "Greek drama" .)

I've seen this clue in The Times.
