But those of The Four Hundred that were most opposite to such a form of government, and the principal of them, both Phrynichus, who had been general at Samos and was ever since at difference with Alcibiades, and Aristarchus, a man that had been an adversary to the people both in the greatest manner and for the longest time, and Pisander and Antiphon, and others of the greatest power, not only formerly, as soon as they entered into authority and afterwards when the state at Samos revolted to the people, sent ambassadors to Lacedaemon and bestirred themselves for the oligarchy, and built a wall in the place called Eetioneia; but much more afterwards, when their ambassadors were come from Samos and that they saw not only the populars but also some others of their own party, thought trusty before, to be now changed.

And to Lacedaemon they sent Antiphon and Phrynichus with ten others with all possible speed, as fearing their adversaries both at home and at Samos, with commission to make a peace with the Lacedaemonians on any tolerable conditions whatsoever or howsoever; and in this time went on with the building of the wall in Eetioneia with greater diligence than before.
