Pentagram (pentacle, pentangle, pentalpha): It was not until the twentieth century that the pentagram became associated with Satanism. In Christianity it served to symbolise the five wounds of Christ, the Greeks thought it had magical properties and in Wiccan / Pagan lore it symbolizes the five elements of earth, air, water, fire and spirit. ...Although ironically, throughout the Middle Ages and Renaissance it was commonly used to ward off witches and demons.
