Pentagram
The pentagram is a five pointed figure formed by producing the sides of a pentagon both ways to their point of intersection, so as to form a five-pointed star
The pentagram (also called pentacle, pentalpha, pentancle, pentagle, or pentangle) is thought by some occultists to trace its esoteric significance to an astronomical observance of the pattern of Venus‘ conjunctions with the Sun and has had many meanings in many cultures through the ages.
