Literally, shield of David. The six-cornered star made by overlapping two triangles is an ancient and widespread symbol. Many ancient architectural ruins carry the engraving of this Hebrew seal. The 3rd- or 4th-century synagogue dug up in Capernaum, Israel, has not only the six-pointed Magen David upon it, but also the rarer five-pointed Seal of Solomon. In 1345, the Emperor Charles IV permitted Jews of Prague to use a flag bearing “the Shield of David and the Seal of Solomon” upon a red field. In modern times, the Shield of David has been the symbol of Zionism and the State of Israel.
