Hexagram: The Hexagram is one of the oldest symbols used universally in ceremonial magic and occult practices. It is shaped as a six-pointed star and is made with two overlapping triangles, one of them inverted. The hexagram represents the divine union of the male and the female and is also seen as the combination of all the four elements of fire, air, water and earth. It is known also as Seal of Solomon and the Jewish religion reveres it as the Star of David. Source: http://www.ancient-symbols.com/occult_symbols.html

Supposedly they would draw it on the palm of their hand to serve as identification to each other. I'll let Donald Duck explain...watch video here.
