A talisman is an object that is considered to possess supernatural or magical powers and is used especially to avert evils, disease, or death. A talisman is typically engraved or cut with figures or characters, constellations, planets, or other heavenly signs. It is often worn as an amulet or charm. From the Greek word “telein”, which means “to initiate into the mysteries”. The word talisman is often used synonymous with amulet.
An amulet is a protecting charm – any object worn to bring good luck and to ward off evil, illness, and harm from supernatural powers and from other people. Amulets are typically carvings, stones (especially with naturally occurring holes), plants (such as sage, 4-leaf clover, shamrock), coins, and jewelry (crosses, horseshoes, gemstones).
