The Pentacle has been a Protective Symbol for thousands of years. Its earliest connections were with the worship of the Earth Mother Goddess; from whose Sacred five pedaled apple blossom and seeds the symbol may have been derived.
It is the simplest form of star that can be drawn with a single line - hence it is sometimes called the Endless Knot.
Other names are: the Goblin's Cross, the Pentalpha, the Witch's Foot, the Devil's Star, and the Seal of Solomon (more correctly attributed to the hexagram).
Like the Circle the Pentacle is considered a Protective Symbol because its continuous lines keep all evil out.
It has also been called The Symbol of Man, of Truth, as well as a Symbol of Completion.
Ancient Alchemists paired the Elements of the Earth to those of Man- Flesh & Bones to Earth, Blood to Water, Breath to Air, Body Heat to Fire, and the Soul to Heavenly Ether.
This Pentacle bears the Runic Alphabet: the Futhark, along its perimeter. This Ancient Magical Nordic Alphabet contains a Mystery of Wisdoms within each letter.
With such Magical Properties encircling the Pentacle a Powerful Defense is created through which naught may penetrate.
It has long been believed to be a Potent Protection against evil and demons, hence a Symbol of Safety.
