Symbols
The Symbols used in
Wicca are diverse, and eclectic. Judeo-Christian, Egyptian, Greek, Chinese, the
art of Symbolism is ever-eclectic in Wicca. I've picked several commonly used
symbols, and I give a brief description of their usage. Personal symbols, such
as a specific Mage's name rune, are sigils, whereas symbols of a God or other
non-human are Symbols or (incorrectly) Runes.

Pentagram.
A
Pentagram is the two-dimensional five pointed star, as opposed to a Pentacle,
which is a three-dimensional representation of a Pentagram. Two points up, the
pentacle represents The horned god, but also has been used to represent
"Satan" a Judeo-Christian God of Evil. Because of this negative use,
many Wiccans only use the feminine, one point up pentacle. Symbols seem to carry
energy from user to user, and the negative energy on the "upside down"
pentacle is almost as strong as that of the Swastika, another once-positive
symbol taken and perverted to near impossible positive use. Most Wiccans only
use the feminine pentacle. pentacle
Trident.
Represents: Neptune, Amphitrite, Aegir, other ocean Gods and Goddesses,
also The Triple Divinity, especially the Male Triple divinities.
Triple Moon:
Represents: The female triple divinity, esp. Hecate, Selene, Diana.
Sigils
Sigils are created by combining the letters of your name into a single design.
Much leeway is allowed with sigils, where the individual letters may be bent,
reversed or otherwise altered to achieve a distinct pattern. This is most
commonly done with runes by Wiccans, but is really much the same as a custom
monogram. (meaning Single symbol, "not initials".)
Creating a Sigil is a great way to mark your tools and other personal items. The power it has relies on the power you give it. Experiment with Runes and other writings until you find a Sigil that fits. Have fun!
