Rhea
Rhea was a well-liked divinity during the time of the Titans. She was married to Kronos, another Titan who overthrew his father Uranus to become the new emperor, making Rhea the new queen. The first generation of Olympian gods, including Hestia, Hades, Poseidon, Hera, and Zeus, are believed to have been conceived by Rhea. She is sometimes referred to be the mother of gods because of this, a term that she deserves far more than preceding deities like Gaea and Cybele.
When she mustered the resolve to deceive her own husband Kronos to preserve her children, she further cemented this position. Kronos would devour every single infant because he was so terrified that his kids would overthrow him. When he was born, Rhea gave him a stone to swallow rather than Zeus to put an end to this madness. The children that Kronos had been swallowing eventually came out of him, and Rhea was able to bring the first of the Olympian gods back to life.
She first appeared in art in the fourth century BC, but because Cybele's features were frequently utilized to portray her, it was difficult to tell the two deities apart. Rhea was frequently represented as a pair of lions pulling a chariot of heaven. The most famous instance of this sign being used on a city gate is at Mycenae, where two stone lions stood watch over the entrance.
