Antiphon, On the murder of Herodes
K. J. Maidment, Ed.

It is their one chance of salvation, especially when the victims of their lies happen not to be present. Had I myself proceeded to give orders that the slave should be racked for not telling the truth, that step in itself would doubtless have been enough to make him stop incriminating me falsely. As it was, the examination was conducted by men who also knew what their own interests required.
