He was preparing for an expedition against Persia when sickness overtook him. Feeling that it was mortal, he desired to be baptised--a stop he had hitherto not taken, although he had for years presided at councils and preached to his people, and even been designated as the "Bishop of bishops." He was received as a catechumen in the church of Heliopolis; he then moved to his palace in the suburbs of Nicomedia, when, calling Eusebius and several other bishops around him, he desired to have the rite administered. Here, having laid aside his purple robes, he was habited in white, and thus, stretched on his death-bed, he received baptism from the hands of Eusebius. One of his last acts was to recall Athanasius, a rival of Eusebius, who had been banished. Thus, with calmness and dignity, he awaited death. His last will he gave into the custody of his chaplain Eustiocius, to be delivered to his eldest son, Constantius, who was now absent; and on the 22nd of May, in the sixty-fourth year of his age, after a reign of thirty years, he expired. His body was conveyed in a coffin of gold to Constantinople, where it lay three months in state, with lights burning around and guards watching. On Eustiocius exhibiting the will to the bishops of Nicomedia, so alarmed were they at the contents that they placed it for security in the hands of the dead man, there to remain until Constantius should appear to receive it. When his eldest son arrived and read the document, he found that the emperor expressed in it his conviction that he had been poisoned by his brothers and their children, and he called-- so it was expressed--on Constantius to avenge his death. This fact alone proves, that whatever amount of Christian knowledge the emperor might have possessed, he had not understood its chief principles, at all events. Constantius faithfully fulfilled his father's dying bequest by the massacre of his uncles and their offspring, amounting to no less than six persons, two alone escaping.
