Talisman, a protective charm, different from an amulet in that it was supposed to derive its efficacy from its being prepared under the influence of the heavenly bodies. It frequently consisted of the figure or character of one or more of the heavenly bodies, engraved on a stone or metal believed to be influenced by them. The distinction is not always observed, and the terms talisman and amulet are often used as if synonymous.
