What is the area of responsibility for the Greek god Rhea?

Area of responsibility...? Ok, Rhea was the wife of Cronos. She had 6 children Demeter, Hades, Hera, Hestia, Poseidon and Zeus. Cronos, afraid that his children would overthrow him, swallowed all of his children whole except Zeus, the youngest. Rhea hid Zeus from Cronos in the Dictaen cave in Crete and gave Cronos a stone wrapped in infant clothes and Cronos swallowed it thinking he had killed all of his children. Zeus grew up and killed his father and made him throw up all of his brothers and sisters. She has some significance in Asia Minor and is known as the great mother. I'm not sure if any of that answers your question or not. Sorry if it doesn't.
