Magical tools were thus very common in magical rituals. Tools were probably just as important as the spells and incantations that were repeated for each magical ritual. A magician's kit, probably dating from the third century, was discovered in the remains of the ancient city of Pergamon in Anatolia and gives direct evidence of this. The find consisted of a bronze table and base covered with symbols, a dish (also decorated with symbols), a large bronze nail with letters inscribed on its flat sides, two bronze rings, and three black polished stones inscribed with the names of supernatural powers.
