5.67.1
In doing this, to my thinking, this Cleisthenes was imitating his own mother's father, Cleisthenes the tyrant of Sicyon, note for Cleisthenes, after going to war with the Argives, made an end of minstrels' contests at Sicyon by reason of the Homeric poems, in which it is the Argives and Argos which are primarily the theme of the songs. Furthermore, he conceived the desire to cast out from the land Adrastus son of Talaus, the hero whose shrine stood then as now in the very marketplace of Sicyon because he was an Argive.
5.67.2
He went then to Delphi, and asked the oracle if he should cast Adrastus out, but the priestess said in response: “Adrastus is king of Sicyon, and you but a stone thrower.” When the god would not permit him to do as he wished in this matter, he returned home and attempted to devise some plan which might rid him of Adrastus. When he thought he had found one, he sent to Boeotian Thebes saying that he would gladly bring Melanippus son of Astacus into his country, and the Thebans handed him over.
5.67.3
When Cleisthenes had brought him in, he consecrated a sanctuary for him in the government house itself, where he was established in the greatest possible security. Now the reason why Cleisthenes brought in Melanippus, a thing which I must relate, was that Melanippus was Adrastus' deadliest enemy, for Adrastus had slain his brother Mecisteus and his son-in-law Tydeus.
5.67.4
Having then designated the precinct for him, Cleisthenes took away all Adrastus' sacrifices and festivals and gave them to Melanippus. The Sicyonians had been accustomed to pay very great honor to Adrastus because the country had once belonged to Polybus, his maternal grandfather, who died without an heir and bequeathed the kingship to him.
5.67.5
Besides other honors paid to Adrastus by the Sicyonians, they celebrated his lamentable fate with tragic choruses in honor not of Dionysus but of Adrastus. Cleisthenes, however, gave the choruses back to Dionysus and the rest of the worship to Melanippus.

5.68.1
This, then, is what he did regarding Adrastus, but as for the tribes of the Dorians, he changed their names so that these tribes should not be shared by Sicyonians and Argives. In this especially he made a laughing-stock of the Sicyonians, for he gave the tribes names derived from the words ‘donkey’ and ‘pig’ changing only the endings. The name of his own tribe, however, he did not change in this way, but rather gave it a name indicating his own rule, calling it Archelaoi, rulers of the people. The rest were Swinites, Assites and Porkites.
5.68.2
These were the names of the tribes which the Sicyonians used under Cleisthenes' rule and for sixty years more after his death. Afterwards, however, they took counsel together and both changed the names of three to Hylleis, Pamphyli, and Dymanatae, and added a fourth which they called Aegialeis after Aegialeus son of Adrastus.
ch. 69
5.69.1
This is what the Sicyonian Cleisthenes had done, and the Athenian Cleisthenes, following the lead of his grandfather and namesake, decided out of contempt, I imagine, for the Ionians, that his tribes should not be the same as theirs.
5.69.2
When he had drawn into his own party the Athenian people, which was then debarred from all rights, he gave the tribes new names and increased their number, making ten tribe-wardens in place of four, and assigning ten districts to each tribe. When he had won over the people, he was stronger by far than the rival faction.
