Pentacle

In the Hermetic Order of the Golden Dawn and Wicca, pentacles symbolize the classical element earth.

[4][5] This is the derivation the Theosophical Society employ in their glossary: ...it seems most likely that it comes through Italian and French from the root pend- "to hang", and so is equivalent to a pendant or charm hung about the neck.

[citation needed] Pentacles showing a great variety of shapes and images appear in the old magical grimoires, such as the Key of Solomon; as Heinrich Cornelius Agrippa summarises it, their use was to "fore-know all future things, & command whole nature, have power over devils, and Angels, and do miracles."

[8]Francis Barrett, in his influential work The Magus of 1801 (Book 2, part 2), repeats these instructions almost verbatim.

[9] In the Golden Dawn magical system, the Earth Pentacle is one of four elemental "weapons" or tools of an Adept.

[2] In many old grimoires dealing with magical evocation, the pentacle is described as being hung about the neck, providing protection and authority to the operator.

Johannes Trithemius has the magician donning the pentacle just before casting the protective circle: Then taking your ring and pentacle, put the ring on the little finger of your right hand; hang the pentacle round thy neck; (Note, the pentacle may be either wrote on clean virgin parchment, or engraven on a square plate of silver and suspended from thy neck to the breast)....[14]One version of the Key of Solomon mentions both a "Great Pentacle" which is drawn in a book, as well as a collection of other pentacles which are drawn in ink on separate pieces of parchment for use as amulets: Thou shalt preserve them to suspend from thy neck, whichever thou wilt, on the day and hour wherein thou wast born, after which thou shalt take heed to name every day ten times, the Name which is hung from thy neck, turning towards the East, and thou mayest be assured that no enchantment or any other danger shall have power to harm thee.

If they then immediately appear, it is well; if not, let the master uncover the consecrated pentacles which he should have made to constrain and command the spirits, and which he should wear fastened round his neck, holding the medals (or pentacles) in his left hand, and the consecrated knife in his right; and encouraging his companions, he shall say with a loud voice:

Here be the symbols of secret things, the standards, the ensigns, and the banners, of God the conqueror; and the arms of the almighty One, to compel the aerial potencies.

If they appear at this time, show them the pentacles, and receive them with kindness, gentleness, and courtesy; reason and speak with them, question them, and ask from them all things which thou hast proposed to demand.

But if, on the contrary, they do not yet make their appearance, holding the consecrated knife in the right hand, and the pentacles being uncovered by the removal of their consecrated covering, strike and beat the air with the knife as if wishing to commence a combat, comfort and exhort thy companions, and then in a loud and stern voice repeat the following conjuration: ...[16] Once the spirit has appeared and been constrained, the pentacle is covered again, but is uncovered whenever demands are made of the spirit or when it is compelled to depart.
