And next to the ruins of Nestane is a temple sacred to Demeter, to whom the Mantineans hold a festival annually. And under Nestane is much of the plain Argum, and the place called Mæras, which is 10 stades from the plain. And when you have gone on no great distance you will come to another plain, in which near the high road is a fountain called Arne. The following is the tradition of the Arcadians about it. When Rhea gave birth to Poseidon, the little boy was deposited with the flocks and fed with the lambs, and so the fountain was called Arne, (_lamb fountain_). And Rhea told Cronos that she had given birth to a foal, and gave him a foal to eat up instead of the little boy, just as afterwards instead of Zeus she gave him a stone wrapt up in swaddling-clothes. As to these fables of the Greeks I considered them childish when I began this work, but when I got as far as this book I formed this view, that those who were reckoned wise among the Greeks spoke of old in riddles and not directly, so I imagine the fables about Cronos to be Greek wisdom. Of the traditions therefore about the gods I shall state such as I meet with. Mantinea is about 12 stades from this fountain. Mantineus, the son of Lycaon, seems to have built the town of Mantinea, (which name the Arcadians still use), on another site, from which it was transferred to its present site by Antinoe, the daughter of Cepheus the son of Aleus, who according to an oracle made a serpent (what kind of serpent they do not record) her guide. And that is why the river which flows by the town got its name Ophis (_serpent_). And if we may form a judgment from the Iliad of Homer this serpent was probably a dragon. For when in the Catalogue of the Ships Homer describes the Greeks leaving Philoctetes behind in Lemnos suffering from his ulcer,[24] he did not give the title serpent to the watersnake, but he did give that title to the dragon whom the eagle dropped among the Trojans.[25] So it seems probable that Antinoe was led by a dragon.
