History of the Peloponnesian War

For in Samos there was a commotion about the oligarchy already; and this that followeth happened about the same time that The Four Hundred were set up in Athens.

Those Samians that had risen against the nobility and were of the people's side, turning when Pisander came thither at the persuasion of him and of those Athenians in Samos that were his accomplices, conspired together to the number of three hundred and were to have assaulted the rest as popular.

And one Hyperbolus, a lewd fellow, who, not for any fear of his power or for any dignity, but for wickedness of life and dishonour he did the city, had been banished by ostracism, they slew, abetted therein both by Charminus, one of the commanders, and by other Athenians that were amongst them, who had given them their faith. And together with these, they committed other facts of the same kind, and were fully bent to have assaulted the popular side.
