Despoina
Despoina or Despoena ( ; Greek: Δέσποινα, romanized: Déspoina) was the epithet of a goddess worshipped by the Eleusinian Mysteries in Ancient Greece as the daughter of Demeter and Poseidon and the sister of Arion. Surviving sources refer to her exclusively under the title Despoina ("the Mistress," cognate of "Despot") alongside her mother Demeter, as her real name could not be revealed to anyone except those initiated into her mysteries and was consequently lost with the extinction of the Eleusinian religion.
