There are 3000 graceful-ankled Okeanids; widely-scattered they haunt the earth and the depths of the waters everywhere alike, shining goddess-children.
And there are as many again of the Rivers that flow with splashing sound, offsprings of Okeanus that Lady Tethys bore.
It is hard for mortal man to tell the names of them all, but each of them are known to the peoples who live near them.
(Hesiod - 8th century b.c.e)
