This is Cronus, he is the king of the world. He defeated his father and took Titan Rhea as his wife and now they rule the world.
Cronus had a lot of children but he feared them so everytime Rhea had a child he would eat them.
I WANT TO EAT YOU!!
Rhea felt upset that Cronus was eating all of her children so she decided to have her last child in a cave and hide him from Cronus so he couldn't eat him.
Rhea had her baby in the cave and brought back a rock to trick Cronus into eating a rock so he didn't know she had the the baby.
Zeus grew up in the cave with the goat, bees and the eagle who would bring him milk, food and honey and they looked after him until he was old enough to go back home and defeat Cronus.
When Zeus was old enough to challenge his father he visited his grandmother who gave him a herb drink which he went to give to his father. Cronus drunk the herbs and spewed up the rock and all his children.
