Terpsichore   

whereas they had till now been called after Geleon, Aegicores,
Argades, and Hoples, the four sons of Ion, Clisthenes set these
names aside, and called his tribes after certain other heroes, all
of whom were native, except Ajax. Ajax was associated because,
although a foreigner, he was a neighbour and an ally of Athens.
My belief is that in acting thus he did but imitate his maternal
grandfather, Clisthenes, king of Sicyon. This king, when he was at war
with Argos, put an end to the contests of the rhapsodists at Sicyon,
because in the Homeric poems Argos and the Argives were so
constantly the theme of song. He likewise conceived the wish to
drive Adrastus, the son of Talaus, out of his country, seeing that
he was an Argive hero. For Adrastus had a shrine at Sicyon, which
yet stands in the market-place of the town. Clisthenes therefore
went to Delphi, and asked the oracle if he might expel Adrastus. To
this the Pythoness is reported to have answered- "Adrastus is the
Sicyonians' king, but thou art only a robber." So when the god would
not grant his request, he went home and began to think how he might
contrive to make Adrastus withdraw of his own accord. After a while he
hit upon a plan which he thought would succeed. He sent envoys to
Thebes in Boeotia, and informed the Thebans that he wished to bring
Melanippus, the son of Astacus, to Sicyon. The Thebans consenting,
Clisthenes carried Melanippus back with him, assigned him a precinct
within the government-house, and built him a shrine there in the
safest and strongest part. The reason for his so doing (which I must
not forbear to mention) was because Melanippus was Adrastus' great
enemy, having slain both his brother Mecistes and his son-in-law
Tydeus. Clisthenes, after assigning the precinct to Melanippus, took
away from Adrastus the sacrifices and festivals wherewith he had
till then been honoured, and transferred them to his adversary.
Hitherto the Sicyonians had paid extraordinary honours to Adrastus,
because the country had belonged to Polybus, and Adrastus was Polybus'
daughter's son; whence it came to pass that Polybus, dying
childless, left Adrastus his kingdom. Besides other ceremonies, it had
been their wont to honour Adrastus with tragic choruses, which they
assigned to him rather than Bacchus, on account of his calamities.
Clisthenes now gave the choruses to Bacchus, transferring to
Melanippus the rest of the sacred rites.
Such were his doings in the matter of Adrastus. With respect to
the Dorian tribes, not choosing the Sicyonians to have the same tribes
as the Argives, he changed all the old names for new ones; and here he
took special occasion to mock the Sicyonians, for he drew his new
names from the words "pig," and "ass," adding thereto the usual
tribe-endings; only in the case of his own tribe he did nothing of the
sort, but gave them a name drawn from his own kingly office. For he
called his own tribe the Archelai, or Rulers, while the others he
named Hyatae, or Pig-folk, Oneatae, or Assfolk, and Choereatae, or
Swine-folk. The Sicyonians kept these names, not only during the reign
of Clisthenes, but even after his death, by the space of sixty
years: then, however, they took counsel together, and changed to the
well-known names of Hyllaeans, Pamphylians, and Dymanatae, taking at
the same time, as a fourth name, the title of Aegialeans, from
Aegialeus the son of Adrastus.
Thus had Clisthenes the Sicyonian done. The Athenian Clisthenes,
who was grandson by the mother's side of the other, and had been named
after him, resolved, from contempt (as I believe) of the Ionians, that
his tribes should not be the same as theirs; and so followed the
pattern set him by his namesake of Sicyon. Having brought entirely
over to his own side the common people of Athens, whom he had before
disdained, he gave all the tribes new names, and made the number
greater than formerly; instead of the four phylarchs he established
ten; he likewise placed ten demes in each of the tribes; and he was,
now that the common people took his part, very much more powerful than
his adversaries.
Isagoras in his turn lost ground; and therefore, to counter-plot
