Dan Brown, author of The Da Vinci Code, also released a book titled The Lost Symbol, and the story contains a number of references to astrology. The novel is the latest installment in a series of stories featuring the main protagonist Robert Langdon, who is supposed to be an expert in religious symbology. But could there be a reality much deeper and greater than what is written in the novel? Is there really a Lost Symbol? And if so, was it intensely coveted by Sir Isaac Newton?
