17. Now to prove that these things are facts and not mere assertions, we have the testimony of all the Presbyters of the Mareotis, who always accompany the Bishop in his visitations, and who also wrote at the time against Ischyras. But neither those of them who came to Tyre were allowed to declare the truth, nor could those who remained in the Mareotis obtain permission to refute the calumnies of Ischyras. The copies also of the letters of Alexander, and of the Presbyters, and of Ischyras will prove the same thing. We have sent also the letter of the father of the Emperors, in which he expresses his indignation that the murder of Arsenius was charged upon any one while the man was still alive; as also his astonishment at the variable and inconsistent character of their accusations with respect to the cup; since at one time they accused the Presbyter Macarius, at another the Bishop Athanasius, of having broken it with his hands. He declares also on the one hand that the Meletians are calumniators, and on the other that Athanasius is perfectly innocent.
