Historia Arianorum

These were the words of the Bishop Liberius. And the eunuch, who was vexed, not so much because he would not subscribe, as because he found him an enemy to the heresy, forgetting that he was in the presence of a Bishop, after threatening him severely, went away with the offerings; and next commits an offense, which is foreign to a Christian, and too audacious for a eunuch. In imitation of the transgression of Saul, he went to the Martyry of the Apostle Peter, and then presented the offerings.

But Liberius having notice of it, was very angry with the person who kept the place, that he had not prevented him, and cast out the offerings as an unlawful sacrifice, which increased the anger of the mutilated creature against him. Consequently he exasperates the Emperor against him, saying, 'The matter that concerns us is no longer the obtaining the subscription of Liberius, but the fact that he is so resolutely opposed to the heresy, that he anathematizes the Arians by name.'

He also stirs up the other eunuchs to say the same; for many of those who were about Constantius, or rather the whole number of them, are eunuchs, who engross all the influence with him, and it is impossible to do anything there without them. The Emperor accordingly writes to Rome, and again Palatines, and Notaries, and Counts are sent off with letters to the Prefect, in order that either they may inveigle Liberius by stratagem away from Rome and send him to the Court to him, or else persecute him by violence.
