Pleione presided over the multiplication of the flocks, fitting, since the meaning of her name is: "to increase in number"[2] (from πλεῖων "more").
Pleione was the daughter of Oceanus and Tethys who were the Titan God and Goddess of bodies of water.
Pleione lived in a southern region of Greece called Arcadia, on a mountain named Mount Kyllini.
She married the Titan Atlas and gave birth to the Hyades, Hyas and the Pleiades.
In some accounts, when Pleione once was travelling through Boeotia with her daughters, Orion who was accompanying her, fell in love with the mother and tried to attack her.
