Dione was a Titan goddess in Greek mythology, most probably a daughter of Oceanus and Tethys and thus, an Oceanid. According to some sources, she was the first wife of Zeus, with whom she had a daughter, the goddess Aphrodite. She was an oracle and was worshipped alongside Zeus at the earliest Oracle in Greece that was located at Dodona. She made an appearance in Homer's Iliad, when her daughter was wounded and she tried to heal her. The priestesses and prophetesses at her shrine in Dodona were called Peleiades or the Doves, which was the sacred bird of her daughter, Aphrodite.
There was also another Dione, a nymph and the daughter of Atlas. She became the wife of king Tantalus, and they had two sons, Pelops and Broteas, and a daughter, Niobe.
