An amulet, similar to a talisman (Arabic: طلسم / tilasim), can be any object but its most important characteristic is its alleged power to protect its owner from danger or harm. Potential amulets include gems, especially engraved gems, statues, coins, drawings, pendants, rings, plants and animals; even words in the form of a magical spell, incantation, to repel evil or bad luck.
The word "amulet" comes from the Latin amuletum; the earliest extant use of the term is in Pliny's Natural History, meaning "an object that protects a person from trouble".
