prophetically

But the most admirable Polycarp, when he first heard [that he was sought for], was in no measure disturbed, but resolved to continue in the city. However, in deference to the wish of many, he was persuaded to leave it. He departed, therefore, to a country house not far distant from the city. There he stayed with a few [friends], engaged in nothing else night and day than praying for all men, and for the churches throughout the world, according to his usual custom. And while he was praying, a vision presented itself to him three days before he was taken; and, behold, the pillow under his head seemed to him on fire. Upon this, turning to those that were with him, he said to them prophetically, “I must be burnt alive.”

While he spoke these and many other like things, he was filled with confidence and joy, and his countenance was full of grace, so that not merely did it not fall as if troubled by the things said to him, but, on the contrary, the proconsul was astonished, and sent his herald to proclaim in the midst of the stadium thrice, “Polycarp has confessed that he is a Christian.” This proclamation having been made by the herald, the whole multitude both of the heathen and Jews, who dwelt at Smyrna, cried out with uncontrollable fury, and in a loud voice, “This is the teacher of Asia, the father of the Christians, and the overthrower of our gods, he who has been teaching many not to sacrifice, or to worship the gods.” Speaking thus, they cried out, and besought Philip the Asiarch to let loose a lion upon Polycarp. But Philip answered that it was not lawful for him to do so, seeing the shows of wild beasts were already finished. Then it seemed good to them to cry out with one consent, that Polycarp should be burnt alive. For thus it behoved the vision which was revealed to him in regard to his pillow to be fulfilled, when, seeing it on fire as he was praying, he turned about and said prophetically to the faithful that were with him, “I must be burnt alive.”
