“The shape of the snail’s shell associated it with the symbolism of the spiral, the whirlwind, the labyrinth, coiled snakes, winding paths, the orbits of heavenly bodies, the ram’s horn, and underground caverns. Spirals are symbols of continuity, evolution, devolution, involution, expansion, contraction, cycles, mysteries, and changes which are the natural result of all that has gone before. Beneficial spirals twirl to the right while destructive ones twirl to the left. Treasures, the self, wisdom, or Minotaurs, other beasts, and nightmares lie at the center of spirals.”
