earth shaker), who is the chthonic aspect of the god Poseidon. Persephone was conflated with Despoina, "the mistress", a chthonic divinity in West-Arcadia. The megaron of Eleusis is quite similar to the "megaron" of Despoina at Lycosura. Demeter is united with her, the god Poseidon, and she bears him a daughter, the unnameable Despoina. Poseidon appears as a horse, as usually happens in Northern European folklore. The goddess of nature and her companion survived in the Eleusinian cult, where the words "Mighty Potnia bore a great sun" were uttered. In Eleusis, in a ritual, one child ("pais") was initiated from the hearth. The name pais (the divine child) appears in the Mycenean inscriptions. In Greek mythology Nysa is a mythical mountain with an unknown location. Nysion (or Mysion), the place of the abduction of Persephone was also probably a mythical place which did not exist on the map, a magically distant chthonic land of myth which was intended in the remote past. Secret rituals and festivals Persephone and Demeter were intimately connected with the Thesmophoria, a widely-spread Greek festival of secret women-only rituals. These rituals, which were held in the month Pyanepsion, commemorated marriage and fertility, as well as the abduction and return of Persephone. They were also involved in the Eleusinian mysteries, a festival celebrated at the autumn sowing in the city of Eleusis. Inscriptions refer to "the Goddesses" accompanied by the agricultural god Triptolemos (probably son of Gaia and Oceanus), and "the God and the Goddess" (Persephone and Plouton) accompanied by Eubuleus who probably led the way back from the underworld. In Rome The Romans first heard of her from the Aeolian and Dorian cities of Magna Graecia, who used the dialectal variant Proserpinē (). Hence, in Roman mythology she was called Proserpina, a name erroneously derived by the Romans from proserpere, "to shoot forth" and as such became an emblematic figure of the Renaissance. In 205 BC, Rome officially identified Proserpina with the local Italic goddess Libera, who, along with Liber, were closely associated with the Roman grain goddess Ceres (considered equivalent to the Greek Demeter). The Roman author Gaius Julius Hyginus also considered Proserpina equivalent to the Cretan goddess Ariadne, who was the bride of Liber's Greek equivalent, Dionysus.
