Now among other things worth seeing in Thesprotia are the temple of Zeus at Dodona, and a beech-tree sacred to the god. And near Cichyrus there is a marsh called Acherusia and the river Acheron, and there too flows Cocytus with most unpleasant stream. And I fancy that Homer, having seen these, ventured to introduce them in his account of the rivers of Hades, and to borrow his names from these rivers in Thesprotia. However that may be, Theseus being detained there, the sons of Tyndarus led an expedition to Aphidna, and captured it, and restored Menestheus to the kingdom. And Menestheus paid no attention to the sons of Theseus, who had gone to Eubœa for shelter to Elephenor; but as to Theseus himself, thinking he would be a dangerous adversary if ever he returned from Thesprotia, he coaxed the people so that if Theseus ever returned he would be sent back again. Accordingly Theseus was sent to Crete to Deucalion, and being carried out of his way by storms to the island Scyrus, the Scyrians gave him a brilliant reception, both for the splendour of his race and the renown of his exploits; and it was owing to this that Lycomedes planned his death. And the shrine of Theseus at Athens was after the time that the Persians were at Marathon, for it was Miltiades’ son, Cimon, that drove out the inhabitants of Scyrus to revenge the hero’s death, and that conveyed his bones to Athens. CHAPTER XVIII. Now the temple of the Dioscuri is ancient; they are designed standing, and their sons seated on horseback. Here too is a painting by Polygnotus of the marriage of the daughters of Leucippus, and by Micon of the Argonauts who sailed with Jason to Colchi: in this painting Acastus and his horses stand out remarkably well. And above the temple of the Dioscuri is the grove of Aglaurus, to whom and to her sisters Erse and Pandrosus they say Athene gave Erichthonius, after putting him in a chest and forbidding them to pry into the contents. Pandrosus they say obeyed, but the other two opened the chest, and went mad when they saw Erichthonius, and threw themselves down the Acropolis at the very steepest place. It was on that very spot that the Persians landed, and slew those Athenians who thought they understood the oracle better than Themistocles, and fortified the Acropolis with wooden palisades. And next is the Prytaneum, where the laws of Solon are written up, and where are images of the goddesses Peace and Vesta, and among other statues one to Autolycus the pancratiast; for Miltiades and Themistocles have been removed for a Roman and a Thracian! As one goes thence to the lower parts of the city is the temple of Serapis, whose worship the Athenians introduced to please Ptolemy. Of the Egyptian temples to Serapis the most famous is that at Alexandria, but the oldest is that at Memphis, into which strangers may not enter, nor even priests except during the ritual in connection with Apis. And not
