Star of David

Star of David, Jewish symbol composed of two overlaid equilateral triangles that form a six-pointed star. It appears on synagogues, Jewish tombstones, and the flag of the State of Israel. The symbol—which historically was not limited to use by Jews—originated in antiquity, when, side by side with the five-pointed star, it served as a magical sign or as a decoration. In the Middle Ages the Star of David appeared with greater frequency among Jews but did not assume any special religious significance; it is found as well on some medieval cathedrals. The term Magen David, which in Jewish liturgy signifies God as the protector (shield) of David, gained currency among medieval Jewish mystics, who attached magical powers to King David’s shield just as earlier (non-Jewish) magical traditions had referred to the five-pointed star as the “seal of Solomon.” Kabbalists popularized the use of the symbol as a protection against evil spirits. The Jewish community of Prague was the first to use the Star of David as its official symbol, and from the 17th century on the six-pointed star became the official seal of many Jewish communities and a general sign of Judaism, though it has no biblical or Talmudic authority. The star was almost universally adopted by Jews in the 19th-century as a striking and simple emblem of Judaism in imitation of the cross of Christianity. The yellow badge that Jews were forced to wear in Nazi-occupied Europe invested the Star of David with a symbolism indicating martyrdom and heroism.
