"Do you know why it's called Solomon's Seal? Solomon used to seal monsters and giants and things into jars. You remember in the Arabian Nights when they'd open the jar and out would come the genie? I noticed the Solomon's Seal here [over the eagle's head], composed of thirteen stars. And then I saw that each of the triangles was a Pythagorean tetrakys, a triangle composed of ten points: one point in the middle and four points to each side... The apex represents the creative center out of which the universe and all things have come."
The Power of Myth with Bill Moyers
"The most iconic symbol of Judaism today is the six-pointed star, or hexagram, made from two interlocking equilateral triangles and known as the Magen David, or Star of David. This motif, however, is not Jewish in origin. In the Hellenistic world, hexagrams were used by all religions, and in the Middle Ages, Jews, Christians, and Muslims alike used them to ward off demons and fires. In the fourteenth century, Jewish mystical texts began associating the image with the shield of God used to protect King David."
