Dione was a Greek goddess and Titan that was the child of Oceanus and Tethys. She was an oracle and worshipped as one of the earliest oracles alongside Zeus, who was located at Dodona.
In some sources, she is named as the mother of Aphrodite and Zeus' first wife. Other sources say she was the child of Uranus and Gaea and that she was the goddess of love.
Dione was certainly considered a Titan, but her actual identity varies.
