There is also a hero-chapel to Hippothoon, from whom a tribe gets its name, and near it one to Zarex, who is said to have learnt music of Apollo. But my own idea is that Zarex was a stranger, a Lacedæmonian who had come into Attica, and that the city Zarex in Laconia by the sea was called after him. But if the hero Zarex was a native of Attica, I know nothing about him. And the river Cephisus flows near the Eleusinian territory with greater speed than before: and here is a place called Erineus, where Pluto they say descended, when he carried off Proserpine. On the banks of this river Theseus slew the robber Polypemon, who was surnamed Procrustes. And the Eleusinians have a temple to Triptolemus, and to Propylæan Artemis, and to Father Poseidon, and a well called Callichorus, where the Eleusinian women first danced and sang songs to the goddess. And the Rharian plain was the first sown and the first that produced crops according to tradition, and this is the reason why it is the custom to use barley from it to make cakes for the sacrifices. Here is shown Triptolemus’ threshing-floor and altar. But what is inside the sacred wall I am forbidden by a dream to divulge, for those who are uninitiated, as they are forbidden sight of them, so also clearly may not hear of the mysteries. And the hero Eleusis, from whom the city gets its name, was according to some the son of Hermes and Daira the daughter of Oceanus, others make him the son of Ogygus. For the ancients, when they had no data for their pedigrees, invented fictitious ones, and especially in the pedigrees of heroes. And as you turn from Eleusis to Bœotia the boundary of Attica is the Platæan district. That was the old boundary between the Athenians and the people of Eleutheræ. But when the people of Eleutheræ became Athenians then Mount Cithæron in Bœotia became the boundary. And the people of Eleutheræ became Athenians not by compulsion, but from hatred to the Thebans and a liking for the Athenian form of government. In this plain too is a temple of Dionysus, and a statue of the god was removed thence to Athens long ago: the one at Eleutheræ now is an imitation of it. And at some distance is a small grotto, and near it a spring of cold water. And it is said that Antiope gave birth to twins and left them in this grotto, and a shepherd finding them near the spring gave them their first bath in it, having stript them of their swaddling clothes. And there was still in my day remains of a wall and buildings at Eleutheræ. This makes it clear that it was a town built a little above the plain towards Mount Cithæron. CHAPTER XXXIX.
