Daughter of Cronus and Rhea (4)
I believe the answer is:
hera
'daughter of cronus and rhea' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hera that I've seen before include "Greek queen of Olympian gods" , "female Greek deity" , "Consort of Zeus" , "Divinity" , "Regularly-deceived wife" .)
