MartPol. 15

When he had offered up the Amen and finished his prayer, the firemen lighted the fire. And, a mighty flame flashing forth, we to whom it was given to see, saw a marvel, yea and we were preserved that we might relate to the rest what happened.

Mart Pol 15.1

The fire, making the appearance of a vault, like the sail of a vessel filled by the wind, made a wall round about the body of the martyr; and it was there in the midst, not like flesh burning, but like [a loaf in the oven or like] gold and silver refined in a furnace. For we perceived such a fragrant smell, as if it were the wafted odor of frankincense or some other precious spice.
