 Traditional medieval Arabic and Hebraic demonology both cultivated the legend of the Ring of Solomon, used to control demons and / or djinn.For example, magic rings in Persian folktales feature in "Arabian Nights", where Judar bin Omar, a fisherman finds the ring of Al-Shamardal, the enchanter and Ma'aruf, the cobbler discovers Shaddád ibn Aad's signet.The powers of both magic rings come from the servant djinn who are magically confined in them.
