Daeira
(
*Da/eira or
Δαῖρα), that is, "the knowing," a divinity connected with the Eleusinian mysteries.
According to Pausanias (
1.38.7) she was a daughter of Oceanus, and became by Hermes the mother of Eleusis; but others called her a sister of Styx; while a third account represents her as identical with Aphrodite, Demeter, Hera, or Persephone. (
Apollon. 3.847; Eustath,
ad Hom. p. 648.)
