Final answer:
The number four holds symbolic meaning in Wiccan traditions, representing the cardinal points of the compass and different aspects of nature.
Step-by-step explanation:
Within Wiccan traditions, the number four holds significant symbolic meaning. When Wiccans gather to worship and perform rituals, they usually establish a religious place outdoors by casting a circle. To mark the boundaries and establish the threshold of the circle, the witch casting it will symbolically 'cut' the circle in three dimensions by walking out the circumference on the ground.
Then, the caster will call on the guardians of the watchtowers of the four directions-north, south, east, and west-to mark the spherical shape. These four directions represent the cardinal points of the compass, and they are associated with different elements and aspects of nature.
