[27] "The Masters and their like also practice the art Pyromancia in a wretched mirror, and make children look into it, whom they then do conjure and also whisper secret words in their ears, and fancy they get much information thereby. But it is all a heresy, the work and allurement of the wicked devil. Christian, have a care! I give thee honest warning. They practise the thing, too, in a beautiful, shining, polished sword.... In the art Pyromancia there is also much other heresy, and especially there is one that is so, the worst and wickedest of all: and the firmer one's belief in it is, the greater is his sinfulness. Here, young boys are said to behold future things and all things in a crystal. Base, desperate, and faint-hearted Christians practise it, to whom the shadow and the phantom of the devil are dearer than the truth of God. Some take a clear and beautifully polished crystal or beryl, which they consecrate and keep clean, and treat with incense, myrrh, and the like. And when they propose to practise their art, they wait for a clear day, or select some clean chamber in which are many candles burning; the masters then bathe, and take the pure child into the room with them, and clothe themselves in pure white garments, and sit down and speak in magic sentences, and then burn their magic offering, and make the boy look into the stone, and whisper in his ears secret words, which have, as they ween, some holy import: verily, those words are of the Devil."
