CHAPTER XX
CONCERNING THE SILKEN CLOTH
WHEN any Instrument of the Art is properly consecrated, it should be wrapped in silk and put away, as we have said.
Take, then, silk of any colour except black or grey, whereon write the words and Characters in Figure 90.
Perfume it with incense of good odour, sprinkle it, and recite Psalms lxxxii.; lxxii.; cxxxiv.; lxiv.
After this thou shalt put it aside for seven days with sweet spices and thou shalt use this silk to wrap all the Instruments of the Art.
