Take this weapon, make and end to your father's cruelty and set your brothers free.
Mother Earth made a sickle out of flint and spoke to her sons, the titans, and asked one to overthrow their father
All the sons except the youngest, Cronus, refused
Uranus couldn't withstand the weapon weilded by his strong son and fled, giving up his powers
Mother Earth Married Pontus, the boundless seas and Cronus married the Titaness Rhea
Mother Earth was mad the Cronus didn't free his brothers but knew that one of his own sons would defeat him. Rhea, sad that Cronus ate their children tricked him by swapping Zeus with a rock and hid Zeus.
Cronus's kid, Zeus, came back and defeated Cronus and got him to throw up his brothers and sisters.
