nature the way the pagans did, and don't even know it. May Day is a perfect example, the celebration of spring... the earth coming back to life to produce her bounty. The mysterious magic inherent in the Divine Proportion was written at the beginning of time. Man is simply playing by Nature's rules, and because art is man's attempt to imitate the beauty of the Creator's hand, you can imagine we might be seeing a lot of instances of the Divine Proportion in art this semester."
Over the next half hour, Langdon showed them slides of artwork by Michelangelo, Albrecht Durer, Da Vinci, and many others, demonstrating each artist's intentional and rigorous adherence to the Divine Proportion in the layout of his compositions. Langdon unveiled PHI in the architectural dimensions of the Greek Parthenon, the pyramids of Egypt, and even the United Nations Building in New York. PHI appeared in the organizational structures of Mozart's sonatas, Beethoven's Fifth Symphony, as well as the works of Bartok, Debussy, and Schubert. The number PHI, Langdon told them, was even used by Stradivarius to calculate the exact placement of the f-holes in the construction of his famous violins.
"In closing," Langdon said, walking to the chalkboard," we return to symbols" He drew five intersecting lines that formed a five-pointed star. "This symbol is one of the most powerful images you will see this term. Formally known as a pentagram - or pentacle, as the ancients called it - this symbol is considered both divine and magical by many cultures. Can anyone tell me why that might be?"
Stettner, the math major, raised his hand. "Because if you draw a pentagram, the lines automatically divide themselves into segments according to the Divine Proportion."
Langdon gave the kid a proud nod. "Nice job. Yes, the ratios of line segments in a pentacle allequal PHI, making this symbol the ultimate expression of the Divine Proportion. For this reason, the five-pointed star has always been the symbol for beauty and perfection associated with the goddess and the sacred feminine."
The girls in class beamed.
"One note, folks. We've only touched on Da Vinci today, but we'll be seeing a lot more of him this semester. Leonardo was a well-documented devotee of the ancient ways of the goddess. Tomorrow, I'll show you his fresco The Last Supper, which is one of the most astonishing tributes to the sacred feminine you will ever see."
"You're kidding, right?" somebody said. "I thought The Last Supper was about Jesus!" Langdon winked. "There are symbols hidden in places you would never imagine."
"Come on," Sophie whispered. "What's wrong? We're almost there. Hurry!"
Langdon glanced up, feeling himself return from faraway thoughts. He realized he was standing at a dead stop on the stairs, paralyzed by sudden revelation.
O, Draconian devil! Oh, lame saint!
Sophie was looking back at him.
It can't be that simple, Langdon thought. But he knew of course that it was. There in the bowels of the Louvre... with images of PHI and Da Vinci swirling through his mind, Robert Langdon suddenly and unexpectedly deciphered Sauniere's code.
"O, Draconian devil!" he said. "Oh, lame saint! It's the simplest kind of code!"
Sophie was stopped on the stairs below him, staring up in confusion. A code? She had been pondering the words all night and had not seen a code. Especially a simple one.
"You said it yourself." Langdon's voice reverberated with excitement. "Fibonacci numbers only have meaning in their proper order. Otherwise they're mathematical gibberish."
Sophie had no idea what he was talking about. The Fibonacci numbers? She was certain they had been intended as nothing more than a means to get the Cryptography Department involved tonight. They have another purpose? She plunged her hand into her pocket and pulled out the printout, studying her grandfather's message again.

O, Draconian devil!
Oh, lame saint!
What about the numbers?
"The scrambled Fibonacci sequence is a clue," Langdon said, taking the printout. "The numbers area hint as to how to decipher the rest of the message. He wrote the sequence out of order to tell us to apply the same concept to the text. O, Draconian devil? Oh, lame saint? Those lines mean nothing.
They are simply letters written out of order."
Sophie needed only an instant to process Langdon's implication, and it seemed laughably simple. "You think this message is... une anagramme?" She stared at him. "Like a word jumble from a newspaper?"
Langdon could see the skepticism on Sophie's face and certainly understood. Few people realized that anagrams, despite being a trite modern amusement, had a rich history of sacred symbolism.
The mystical
