A five-pointed star, also called a pentagram or pentalpha.
See illustr. under pentalpha. Sometimes referring to a
similar figure, such as the figure composed of two
equilateral triangles intersecting so as to form a
six-pointed star. It was used in early ornamental art, and
also with superstitious import by the astrologers and mystics
of the Middle Ages. The six-pointed star is more comonly
called a hexagram, or called Solomon's seal; it resembles
the star of David (Magen David)
