Once more a love story of Zeus, who else? This time he had an affair with his sister Demeter, as you can see there were no taboos for the powerful Zeus. Demeter gave birth to the very beautiful Kore. She lived half a year as Queen in the underworld and the other half of the year up on the Olympus. As the Queen of the underworld later she got known as Persephone. So Zeus also slept with Persephone slipping inside her in the shape of a snake. How you can see it needs a lot of fantasy in the mythological stories, but especially this I like a lot. However also Persephone got pregnant and gave birth to Zagreus. He became the favorite son of Zeus and should get all his knowledge, ability and wealth.
The more Zeus loved him the more Hera hated this son. And once more Zeus hid him and the small gods the Kuerten looked after him. But this time Hera hated Zagreus so much that she send the titans to find him. They searched him all around the world and one day they found him in a small cave. But the titans were to huge to enter the cave and Zagreus was not going to come out that easy. They enticed him out of the cave with a mirror, something Zagreus never saw before. They caught him and tore him in many pieces. As you can see mythology can be really rude and does not shrink for anything. Also the many love affairs and to be unfaithful remember to the human being of today.
As Zeus got to know about the death of his favorite son he raged and burned the titans to death.
