Goddess symbols, individualized for each goddess, were incorporated into the worship of the ancient goddesses, were often worn as jewelry, and also used in the household decor as talismans to seek the goddesses special gifts, blessings, or protection. A large number of goddess symbols have survived in statuary and other works of art.
Many of the goddess symbols come from the legends surrounding a specific goddess and were “characters” in her story. Other goddess symbols were derived from the rituals used in the ancient rites of worship of these pagan goddesses.
Hecate, “The Distant One” ( best known as Hecate, Greek goddess of the Crossroads) is often represented by symbols associated with her personality traits and her role as Queen of the Night. Since Hecate is the goddess of witchcraft, it should come as no surprise that many of her goddess symbols play a prominent role in the celebration of Halloween.
