Of The Images of Mercury
The Magus, or Celestial Intelligencer

FROM the operations of Mercury they made an image of Mercury, Mercury ascending in Gemini; the form of which was a handsome young man, bearded, having in his left hand a rod, round which a serpent was entwined--in the right he carried a dart; having his feet winged. They say that this image confers knowledge, eloquence, diligence in merchandise, and gain; moreover, to obtain peace and concord, and cure fevers. They made another image of Mercury, ascending in Virgo, for good will, wit, and memory; the form of which was a man sitting upon a chair, or riding on a peacock, having eagle's feet, and on his head a crest, and in his left hand holding a cock of fire.
