The Seal of Solomon is the microsom star, a sign of spiritual potential, the ability for endless self-overcoming, individuality, a symbol of the human soul as a combination of the conscious and the unconscious. Denoted by the interlacing of the sign of the element fire - a triangle with the top up and a triangle turned down - denoting water.
It was believed that this symbol, placed on the legendary signet ring of King Solomon, gave him power over genies and the ability to talk with animals.
