Nysa (Νυσα) whose name means "Of Mount Nysa" is one of the Nysiades. She was one of the Okeanides who took care of Dionysios on Mount Nysa until he was grown. This was done so that if Dionysios was hidden he could avoid the wrath of Hera.
When Dionysios grew up and began spreading the gift of wine with the world the Nysiades along with Silenius became his first followers and became known as Maenad.
- Pseudo-Hyginus, Fabulae 182
"Daughters of Oceanus . . . Their [the Nysiades] names are Cisseis, Nysa, Erato, Eriphia, Bromis, Polyhymno. On Mount Nysa these obtained a boon from their foster-son, who made petition to Medea. Putting off old age, they were changed to young girls, and later, consecrated among the stars, they are called Hyades. Others report that they were called Arsinoe, Ambrosie, Bromie, Cisseis, and Coronis."
