An incantation vessel, also known as a demon bowl, devil-trap bowl, or magic bowl, is a form of early protective magic found in what is now Iraq and Iran. Produced in the Middle East during late antiquity from the sixth to eighth centuries, particularly in Upper Mesopotamia and Syria, the bowls were usually inscribed in a spiral, beginning from the rim and moving toward the center. Most are inscribed in Jewish Babylonian Aramaic. The bowls were buried face down and were meant to capture demons. They were commonly placed under the threshold, courtyards, in the corner of the homes of the recently deceased and in cemeteries.
