Jewish Magical Rings of Power
According to the Testament of Solomon, a pseudepigraphic work of late Antiquity that serves as the basis for a whole genre of Solomonic magical lore, King Sol created a ring using a divine name of power and inscribed it with a seal, either a pentagram or hexagram (traditions vary). With this ring, he was able to enslave demons and he compelled them to help him construct the Temple in Jerusalem - a mythic illustration of the Jewish belief that there is nothing in the universe that is irredeemable, or cannot be bent to divine service.
But this is not the only ring of power in Jewish literature. Josephus also mentions a magical ring used to perform an exorcism in his native Judea (Antiquities 8).
In the Hechalot literature, rings and seals a recurrent theme. Both angels (Hechalot Rabbati) and adepts (Merkavah Rabbah) use rings with seals to tap into divine forces.
But it is Solomon’s ring that has captured the imagination of readers over the centuries. Not only is it good for exorcisms and demon management, but it also gives you the power to speak with animals. Discussions, recipes, and diagrams of the ring repeatedly appear in works such as the medieval work, Mafteach Shlomo (The Key of Solomon) and is invoked on amulets for protection against demons (Naveh and Shaked, Magic Spells and Formulae, p. 93).
