Book 6
20.2
At the foot of Mount Cronius, on the north...,Some genitive seems to have fallen out here. τοῦ Ἡραίου and τῆς Ἄλτεως have been suggested. Other conjectures are: (1) to insert τεῖχος after ἄρκτον, to read Ἄλτιν for ἄρκτον. between the treasuries and the mountain, is a sanctuary of Eileithyia, and in it Sosipolis,“Saviour of the State.” a native Elean deity, is worshipped. Now they surname Eileithyia Olympian, and choose a priestess for the goddess every year. The old woman who tends Sosipolis herself too by an Elean custom lives in chastity, bringing water for the god's bath and setting before him barley cakes kneaded with honey.
20.3
In the front part of the temple, for it is built in two parts, is an altar of Eileithyia and an entrance for the public; in the inner Part Sosipolis is worshipped, and no one may enter it except the woman who tends the god, and she must wrap her head and face in a white veil. Maidens and matrons wait in the sanctuary of Eileithyia chanting a hymn; they burn all manner of incense to the god, but it is not the custom to pour libations of wine. An oath is taken by Sosipolis on the most important occasions.
20.4
The story is that when the Arcadians had invaded the land of Elis, and the Eleans were set in array against them, a woman came to the Elean generals, holding a baby to her breast, who said that she was the mother of the child but that she gave him, because of dreams, to fight for the Eleans. The Elean officers believed that the woman was to be trusted, and placed the child before the army naked.
20.5
When the Arcadians came on, the child turned at once into a snake. Thrown into disorder at the sight, the Arcadians turned and fled, and were attacked by the Eleans, who won a very famous victory, and so call the god Sosipolis. On the spot where after the battle the snake seemed to them to go into the ground they made the sanctuary. With him the Eleans resolved to worship Eileithyia also, because this goddess to help them brought her son forth unto men.
