Plutarch, Pericles
Bernadotte Perrin, Ed.

About this time also Aspasia was put on trial for impiety, Hermippus the comic poet being her prosecutor, who alleged further against her that she received free-born women into a place of assignation for Pericles. And Diopeithes brought in a bill providing for the public impeachment of such as did not believe in gods, or who taught doctrines regarding the heavens, directing suspicion against Pericles by means of Anaxagoras. [2] The people accepted with delight these slanders, and so, while they were in this mood, a bill was passed, on motion of Dracontides, that Pericles should deposit his accounts of public moneys with the prytanes, and that the jurors should decide upon his case with ballots which had lain upon the altar of the goddess on the acropolis. But Hagnon amended this clause of the bill with the motion that the case be tried before fifteen hundred jurors in the ordinary way, whether one wanted to call it a prosecution for embezzlement and bribery, or malversation. [3]

Well, then, Aspasia he begged off, by shedding copious tears at the trial, as Aeschines says, and by entreating the jurors; and he feared for Anaxagoras so much that he sent him away from the city. And since in the case of Pheidias he had come into collision with the people, he feared a jury in his own case, and so kindled into flame the threatening and smouldering war, hoping thereby to dissipate the charges made against him and allay the people's jealousy, inasmuch as when great undertakings were on foot, and great perils threatened, the city entrusted herself to him and to him alone, by reason of his worth and power. Such, then, are the reasons which are alleged for his not suffering the people to yield to the Lacedaemonians; but the truth about it is not clear.
