Triple goddess symbol
One of the most well known Wiccan symbols, the Triple Goddess is depicted in several different ways. One example is a circle with an inverted crescent moon on each side. Used as a symbol of Wiccan recognition, the Triple Goddess Symbol signifies the changes of life, birth and death as well as the three aspects of the moon. Believing that as the moon moves through its waxing, waning and full cycle, life corresponds. As the Goddess is the Wiccan symbol for the feminine polarity of the universe, the Triple Goddess Symbol signifies the maiden, motherhood and crone stages of womanhood.
The pentagram inside the full moon (in the centre) makes it a pentacle The upward point of the star is representative of the spirit. The other four points all represent an element; earth, air, fire, and water. All these things contribute to life and are a part of each of us. A circle around a pentagram contains and protects. The circle symbolises eternity and infinity, the cycles of life and
nature. The circle touching all 5 points indicates that the spirit, earth, air, water and fire are alll connected.
To wear a pentagram necklace or other form of jewelry, is to say you feel the connection with the elements and respect the earth.
