The History and Folklore of the Sard and Serpentine

The Italian peasants of to-day believe that pebbles of green serpentine afford protection from the bites of venomous creatures. These stones are usually green with streaks or veins of white, and the name was derived from their fancied resemblance to a serpent's skin. In addition to their prophylactic powers, if any one has been bitten by such a creature, the stone, when applied to the wound, is supposed to draw out the poison. Here, as in the case of coral, the hand of man must not have shaped the amulet; it should be in its natural state. As a general rule, however, the belief that the touch of any iron instrument, such as the tool of the gem-cutter, destroys the magic efficacy of the substance, is less firmly held in regard to stones than in reference to coral.
