Rhea

Rhea or Rheia (/ˈriːə/; Ancient Greek: Ῥέα [r̥é.aː] or Ῥεία [r̥ěː.aː]) is a mother goddess in ancient Greek religion and Greek mythology, the Titaness daughter of the earth goddess Gaia and the sky god Ouranos, himself a son of Gaia. She is the older sister of Kronos, who was also her consort, and the mother of the five eldest Olympian gods Hestia, Demeter, Hera, Poseidon and Zeus, and the king of the Underworld, Hades.
When Kronos learnt that he was destined to be overthrown by one of his children like his father was before him, he swallowed all the children Rhea bore as soon as they were born. When Rhea had her sixth and final child, Zeus, she spirited him away and hid him in Crete, giving Kronos a rock to swallow instead, thus saving her youngest son who would go on to challenge his father's rule and rescue the rest of his siblings. Following Zeus' defeat of Kronos and the rise of the Olympian gods into power, Rhea withdraws her role as the queen of the gods to become a supporting figure on Mount Olympus. She has some roles and myths in the new Olympian era; she attended the birth of her grandson Apollo and raised her other grandson Dionysus, after Persephone was abducted by Hades, Rhea was sent to Demeter by Zeus, while in the myth of Pelops, she brings back the unfortunate youth to life after he was slain.
In early traditions, she is known as "the mother of gods" and therefore is strongly associated with Gaia and Cybele, who have similar functions. The classical Greeks saw her as the mother of the Olympian gods and goddesses.
