“Meanwhile the emperor, being desirous of personally examining Arius, sent for him to the palace, and asked him whether he would assent to the determinations of the Synod at Nicaea. He without hesitation replied in the affirmative, and subscribed the declaration of the faith in the emperor’s presence, acting with duplicity. The emperor, surprised at his ready compliance, obliged him to confirm his signature by an oath. This also he did with equal dissimulation. The way he evaded, as I have heard, was this: he wrote his own opinion on paper, and carried it under his arm, so that he then swore truly that he really held the sentiments he had written. That this is so, however, I have written from hearsay, but that he added an oath to his subscription, I have myself ascertained, from an examination of the emperor’s own letters. The emperor being thus convinced, ordered that he should be received into communion by Alexander, bishop of Constantinople. It was then Saturday, and Arius was expecting to assemble with the church on the day following: but divine retribution overtook his daring criminalities. For going out of the imperial palace, attended by a crowd of Eusebian partisans like guards, he paraded proudly through the midst of the city, attracting the notice of all the people. As he approached the place called Constantine’s Forum, where the column of porphyry is erected, a terror arising from the remorse of conscience seized Arius, and with the terror a violent relaxation of the bowels: he therefore enquired whether there was a convenient place near, and being directed to the back of Constantine’s Forum, he hastened thither. Soon after a faintness came over him, and together with the evacuations his bowels protruded, followed by copious hemorrhage, and the descent of the smaller intestines: moreover portions of his spleen and liver were brought off in the effusion of blood, so that he almost immediately died. The scene of this catastrophe still is shown at Constantinople, as I have said, behind the shambles in the colonnade: and by persons going by pointing the finger at the place, there is a perpetual remembrance preserved of this extraordinary death. So disastrous an occurrence filled with dread and alarm the party of Eusebius, bishop of Nicomedia; and the report of it quickly spread itself over the city and throughout the world.”
