Loadstone is a precious stone that is believed to possess a variety of magical qualities. When ill one holds it in the hands and shakes it well; it cures wounds, snakebites, weak eyes, headaches, and restores health.
A saying has it that the possessor of the loadstone may walk through reptiles in safety, even when the “black death” accompanies them. Orpheus said, “with this stone you can hear the voices of the gods and learn many wonderful things;” that it has the property of unfolding the future; and if held close to the eyes it will inspire the divine spirit. A.G.H.
