Seal of Solomon. In Medieval Jewish, Christian and Islamic legends, the Seal of Solomon was a magical signet ring said to have been possessed by King Solomon, which variously gave him the power to command demons, genies, or to speak with animals.
Solomon’s Seal on an Abbasid coin ~13th century. Magen David centered with a representation of each Tribe at the end of each cross-bar. The three dots centered may possibly represent King, Holiness, Redeemer consecutively. Very beautiful seal.
