NEAIRA (or Neaera) was a nymph of the island of mythical island Thrinakia who was loved by the sun-god Helios. She bore him two shining daughters, the rustic nymphs Lampetia and Phaethousa.
Thrinakia may be the same as Trinakria, an old Greek name for the island of Sicily. Her name "newly-risen" is descriptive of the dawn sun, and she was probably the goddess of the sun's risings, just as her daughters might have represented the days of the year.
NEAERA (Neaira). A nymph, who became by Helios the mother of Lampetia and Phaetusa. (Hom. Od. xii. 133.)

"Lovely-haired Nymphai named Phaethousa and Lampetie, whose father is the sun-god Hyperion [i.e. Helios] and whose mother is bright Neaira; having borne and bred them, she took them away to remote Thrinakia (Thrinacia) to live there and tend their father's sheep and the herds with curling horns."
