Clymene

Clymene in the daughter Oceanus and Tethys, with many adopted sisters.
She was paired with the older Iapetus, who won her over with gifts and charm.
As she grew older, Clymene became disillusioned with her mate and had an affair with Helios. Her son, Atlas, was aware of the affair, though her never told Iapetus. As a result, he has grown quite distanced from his mother, while Helios comforted her in her days of mourning.
