The discovery of Isaac Newton’s secret papers in 1936 had stunned the world by revealing Newton’s all-consuming passion for the study of ancient alchemy and mystical wisdom. Newton’s private papers included a handwritten letter to Robert Boyle in which he exhorted Boyle to keep “high silence” regarding the mystical knowledge they had learned. “It cannot be communicated,” Newton wrote, “without immense damage to the world.”
The meaning of this strange warning was still being debated today.
“Professor,” Sato said suddenly, glancing up from her BlackBerry, “despite your insistence that you have no idea why you’re here tonight, perhaps you could shed light on the meaning of Peter Solomon’s ring.”
“I can try,” Langdon said, refocusing.
She produced the specimen bag and handed it to Langdon. “Tell me about the symbols on his ring.”
Langdon examined the familiar ring as they moved through the deserted passageway. Its face bore the image of a double-headed phoenix holding a banner proclaiming ORDO AB CHAO, and its chest was emblazoned with the number 33. “The double-headed phoenix with the number thirty-three is the emblem of the highest Masonic degree.” Technically, this prestigious degree existed solely within the Scottish Rite. Nonetheless, the rites and degrees of Masonry were a complex hierarchy that Langdon had no desire to detail for Sato tonight. “Essentially, the thirty-third degree is an elite honor reserved for a small group of highly accomplished Masons. All the other degrees can be attained by successful completion of the previous degree, but ascension to the thirty-third degree is controlled. It’s by invitation only.”
“So you were aware that Peter Solomon was a member of this elite inner circle?”
“Of course. Membership is hardly a secret.”
“And he is their highest-ranking official?”
“Currently, yes. Peter heads the Supreme Council Thirty-third Degree, which is the governing body of the Scottish Rite in America.” Langdon always loved visiting their headquarters — the House of the Temple — a classical masterpiece whose symbolic ornamentation rivaled that of Scotland’s Rosslyn Chapel.
“Professor, did you notice the engraving on the ring’s band? It bears the words ‘All is revealed at the thirty-third degree.’ ”
Langdon nodded. “It’s a common theme in Masonic lore.”
“Meaning, I assume, that if a Mason is admitted to this highest thirty-third degree, then something special is
“Yes, that’s the lore, but probably not the reality. There’s always been conspiratorial conjecture that a select few within this highest echelon of Masonry are made privy to some great mystical secret. The truth, I suspect, is probably far less dramatic.”
Peter Solomon often made playful allusions to the existence of a precious Masonic secret, but Langdon always assumed it was just a mischievous attempt to coax him into joining the brotherhood. Unfortunately, tonight’s events had been anything but playful, and there had been nothing mischievous about the seriousness with which Peter had urged Langdon to protect the sealed package in his daybag.
Langdon glanced forlornly at the plastic bag containing Peter’s gold ring. “Director,” he asked, “would you mind if I held on to this?”
She looked over. “Why?”
“It’s very valuable to Peter, and I’d like to return it to him tonight.”
She looked skeptical. “Let’s hope you get that chance.”
“Thanks.” Langdon pocketed the ring.
“Another question,” Sato said as they hastened deeper into the labyrinth. “My staff said that while cross-checking the concepts of the ‘thirty-third degree’ and ‘portal’ with Masonry, they turned up literally hundreds of references to a ‘
“That’s not surprising, either,” Langdon said. “The pyramid builders of Egypt are the forerunners of the modern stonemasons, and the pyramid, along with Egyptian themes, is very common in Masonic symbolism.”
“Symbolizing what?”
“The pyramid essentially represents enlightenment. It’s an architectural symbol emblematic of ancient man’s ability to break free from his earthly plane and ascend upward toward heaven, toward the golden sun, and ultimately, toward the supreme source of illumination.”
She waited a moment. “Nothing else?”
“According to my staff,” she said, “it sounds like there is a much more relevant connection tonight. They tell me there exists a popular legend about a
