Musonius Rufus then made a violent attack on Publius Celer, accusing him of having brought about the destruction of Barea Soranus by perjury. By this impeachment all the hatreds of the days of the informers seemed to be revived; but the accused person was so worthless and so guilty that he could not be protected. For indeed the memory of Soranus was held in reverence; Celer had been a professor of philosophy, and had then given evidence against Barea, thus betraying and profaning the friendship of which he claimed to be a teacher. The next day was fixed for the trial. But it was not of Musonius or Publius, it was of Priscus, of Marcellus, and his brother informers, that men were thinking, now that their hearts were once roused to vengeance.
