Recollect, too, that in those very days, Catholic bigotry had broken out in a general plunder of the Jews. At Rome, at Milan, and Genoa their houses had been sacked, and their synagogues burnt; and Dietrich, having compelled the Catholics to rebuild them at their own expense, had earned the hatred of a large portion of his subjects. And now Pope John was doing all he could to thwart him. Dietrich bade him go to Constantinople, and plead with Justin for the persecuted Arians. He refused. Dietrich shipt him off, nolentem volentem. But when he got to Constantinople he threw his whole weight into the Emperor's scale. He was received by Justin as if he was St. Peter himself, the Emperor coming out to meet him with processions and wax-lights, imploring his blessing; he did exactly the opposite to what Dietrich bade him do; and published on his return a furious epistle to the bishops of Italy, calling upon them to oppress and extirpate the Arian perfidy, so that no root of it is left: to consecrate the Arian churches wheresoever he found them, pleading the advice of the most pious and Christian Emperor Justin, talking of Dietrich as tainted inwardly and wrapt up outwardly with the pest of heresy. On which Cochlaeus (who religiously believes that Dietrich was damned for his Arianism, and that all his virtues went for nothing because he had not charity, which exists, he says, alone within the pale of the Church), cannot help the naive comment, that if the Pontiff did really write that letter, he cannot wonder at Dietrich's being a little angry. Kings now, it is true, can afford to smile at such outbursts; they could not afford to do so in Dietrich's days. Such words meant murder, pillage, civil war, dethronement, general anarchy; and so Dietrich threw Pope John into prison. He had been in bad health before he sailed to Constantinople, and in a few months he died, and was worshipped as a saint.
