Pentagram
More recently, the meaning of the pentagram was discussed in The Da Vinci Code by Dan Brown. According to the book, the pentagram actually belonged to the ancient religion of Pagan Sun Worship, and was tied to the female planet Venus: every 8 years Venus traces a perfect pentagram across the sky. The book says that the pentagram was a symbol for the sacred female, but was later taken by Christianity and said to mean the devil in order to destroy beliefs that females were sacred.
