The other chapel, which was lined with the star-stone, did only cast a splendorous and comfortable light; both the chapels stood upon pillars, just in the middle of a round cloister, which was dark as night; neither was there any other light within them, but what came from the fire- and star-stone; and being everywhere open, allowed to all that were within the compass of the cloister, a free prospect into them; besides, they were so artificially contrived, that they did both move in a circle about their own centres, without intermission, contrary ways. In the chapel which was lined with the fire-stone, the Empress preached sermons of terror to the wicked, and told them of the punishments for their sins, to wit, that after this life they should be tormented in an everlasting fire.
