Ouranus and Gaia were the gods of the sky and the Earth respectively. They became partners, and brought forth their children: the Cyclopes, the Hecatonchires and the Titans. When Ouranos saw his other children, he did not think they should not walk on the earth so he casted them into Tartarus and used Kampe as the jailer. Gaia was enraged with Ouranos and told Kronos to cut his father to pieces with a sickle, and he did so, making him the Lord of the the universe. But Kronos still did not free his brothers.
The Hundred-Handed GiantsEdit
Ouranos didn't care for his children, in fact, he hated them. Most of all he hated his children that did not look normal, such as the Hecatonchires and Cyclopes. They were unsightly in his opinion, and he wanted them gone. But he couldn't kill them, because they were immortal.
So instead Ouranos threw the Hecatonchires and Cyclopes into Tartarus. This caused Gaea pain, and she was also furious because they were her children, and Ouranos cared nothing for them. She asked her children, the Titans, to get rid of Ouranos so she could save her other children, and only Kronos was brave enough to do it. He took a flint sickle Gaea made, and sliced his father into pieces. Nothing else was mentioned about Ouranus after that.
Ouranus was a horrible father, and didn't care for his children. He was a terrible husband too, because it didn't hurt him that Gaia was so sad about the loss of her children.
