Because of its geometric symmetry, the hexagram has been a popular symbol in many cultures from earliest times. Anthropologists claim that the triangle pointing downward represents female sexuality, and the triangle pointing upward, male sexuality; thus, their combination symbolizes unity and harmony. In alchemy, the two triangles symbolize *"fire" and *"water"; together, they represent the reconciliation of opposites. Some medieval alchemists even borrowed the talmudic pun - ish mayim, fiery water, and shamayim , heaven - to demonstrate the interpenetration of the two realms. 1 Because if this symbolism, the hexagram was even used occasionally as the emblem displayed above a brandy shop.
The earliest known Jewish use of the hexagram was as a seal in ancient Israel (6th century B.C.E.) and then eight centuries later in a *synagogue frieze in Capernaum. But these early hexagrams may have been only ornamental designs; ironically, a swastika, another popular ancient motif, appears alongside the hexagram on the Capernaum synagogue wall. In the Middle Ages, hexagrams appear frequently on churches, but rarely in synagogues or on Jewish ritual objects. It was the *menorah that served as the primary Jewish symbol from antiquity until the post-Renaissance period, not the " Jewish star."
Although scholars have attempted to trace the Star of David back to King David himself; to Rabbi Akiva and the Bar Kokhba ("son of the star") rebellion (135 C.E.); or to *kabbalists, especially Rabbi Isaac Luria (16th century), no Jewish literature or artifacts document this claim. Rather, all evidence suggests that the early use of the hexagram was limited to "practical Kabbalah," that is, Jewish magic, probably dating back to the 6th century C.E. Legends connect this symbol with the "Seal of Solomon," the magical signet signet *ring used by King Solomon to control demons and spirits. 2 Although the original ring was inscribed with the Tetragrammaton, the sacred Four-Letter *Name of God, medieval *amulets imitating this ring substituted the hexagram or pentagram (five-pointed stare), often accompanied by rampant *lions, for the sacred Name. The star inscribed on these rings was usually called the "Seal of Solomon."
In addition to such legends about Solomon's ring, medieval Jewish magical texts spoke of a magic shield possessed by King David which protected him from his enemies. According to these texts, the shield was inscribed with the seventy-two letter name of God, or with Shaddai (Almighty) or *angelic names, and was eventually passed down to *Judah Maccabee. The 15th-century kabbalist, Isaac Arama, claimed that Psalm 67, later known as the "Menorah Psalm" because of its *seven verses (plus an introductory verse), was engraved on David's shield in the form of a menorah. Another tradition suggests that Isaiah 11:2, enumerating the six aspects of the divine spirit, was inscribed on the shield in the outer six triangles of the hexagram. 3 In time, the hexagram replaced this menorah in popular legends about David's shield, while the five-pointed pentagram became identified with the Seal of Solomon.
The hexagram was also widely regarded as a messianic symbol, because of its legendary connection with David, ancestor of the *Messiah. On Sabbath eve, German Jews would light a star-shaped brass *oil *lamp called a Judenstern (Jewish star), emblematic of the idea that Shabbat was a foretaste of the Messianic Age. The hexagram was also popular among the followers of Shabbatai Tzevi, the false messiah of the 17th century, because of its messianic associations.
