FRom the operations of Mars they made an Image in the hour of Mars, Mars ascending in the second face of Aries, in a Martiall stone, especially in a Diamond; The form of which was a man armed, riding upon a Lyon, having in his right hand a naked sword erected, carrying in his left hand the head of a man; they report, that an Image of this kind rendreth a man powerfull in good and evill, so that he shall be feared of all; and whosoever carryeth it they give him the power of enchantment, so that he shall terrifie men by his looks when he is angry, and stupifie them; they made another Image of Mars for the obtaining of boldness, courage, and good fortune in wars, and contentions, the form of which was a souldier armed and crowned, girt with a sword, carrying in his right hand a long Lance; and they made this at the hour of Mars, the first face of Scorpio ascending with it.
