Celtic spiral

Spirals are a frequent occurrence in nature; from snails right up to galaxies, so it seems like a natural motif for the Celts to pick up on. They were nearly always drawn in a clockwise manner, which some experts say is in keeping with the direction of the sun. Therefore, the spiral is symbol of being in harmony with the earth and sun, honoring our connection with Nature.
The 3 branch Spiral represents the triple goddess, three female figures, described as the maiden, the mother, and the crone, each of which symbolizes both a separate stage in the female life cycle (maiden: innocent and pure — mother: compassionate and nurturing — crone: experienced and wise)
