  • Pentacle \Pen"ta*cle\, n. [Gr. pe`nte five.] 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) [1913 Webster + PJC]
