15. A MIRACLE
Then the fire was lit, and the flame blazed furiously. We who were privileged to witness it saw a great miracle, and this is why we have been preserved, to tell the story.
The fire shaped itself into the form of an arch, like the sail of a ship when filled with the wind, and formed a circle around the body of the martyr. Inside it, he looked not like flesh that is burnt, but like bread that is baked, or gold and silver glowing in a furnace. And we smelt a sweet scent, like frankincense or some such precious spices.
16. THE DEATH OF POLYCARP
Eventually, when those wicked men saw that his body could not be consumed by the fire, they commanded an executioner to pierce him with a dagger. When he did this [a dove flew out and] [*this may well be a later interpolation or transcription error] such a great quantity of blood flowed that the fire was extinguished. The crowd were amazed at the difference between the unbelievers and the elect ÔÇô of whom the great Polycarp was surely one, having in our own times been an apostolic and prophetic teacher, and bishop of the Catholic Church in Smyrna. For every word he spoke either has been or shall be accomplished.
