The pentacle is regarded as sacred geometry and a powerful protective symbol for thousands of years. Found within the design of Nature, from the five-petaled apple blossom to the seed configuration within the fruit itself, it carries association with witchcraft, mysticism and the Goddess. The tradition of ceremonial magic designates the points as representative of the elements: Earth, Air, Fire, Water, and Spirit at the topmost. It is the contemporary religious symbol of Wicca and Neo-paganism. Artist Paul Borda comments, "If I could choose just one aspect of the design that I find engaging it would be the balance between the Celtic knotwork and the spiral patterning. The knotwork on the pentagram with its interlocking lines, always alternating between going over and going under, feels masculine to me and therefore represents the God. The crescent with the triform swirling spirals, smoothly interacting with each other yet never crossing each others boundaries, feels feminine to me and represents the Goddess. Together, I feel that the two design styles represent the union of Goddess and God enjoined in the sacred marriage." About the rim of the design reads "I am the beauty of the green earth, and the white moon among the stars", a line from the "Charge of the Goddess" by Wiccan poet Doreen Valiente.
