The Lost Symbol

“It’s alchemical,” Katherine said, sliding her chair closer and examining Langdon’s finger. “It’s the ancient symbol for gold.”

“Indeed it is.” The dean smiled and patted the box. “Professor, congratulations. You have just achieved what every alchemist in history has strived for. From a worthless substance, you’ve created gold.”

Langdon frowned, unimpressed. The little parlor trick seemed to be no help at all. “An interesting idea, sir, but I’m afraid this symbol — a circle with a round dot in the middle — has dozens of meanings. It’s called a circumpunct, and it’s one of the most widely used symbols in history.”

“What are you talking about?” the dean asked, sounding skeptical.

Langdon was stunned that a Mason was not more familiar with the spiritual importance of this symbol. “Sir, the circumpunct has countless meanings. In ancient Egypt, it was the symbol for Ra — the sun god — and modern astronomy still uses it as the solar symbol. In Eastern philosophy, it represents the spiritual insight of the Third Eye, the divine rose, and the sign of illumination. The Kabbalists use it to symbolize the Kether — the highest Sephiroth and ‘the most hidden of all hidden things.’ Early mystics called it the Eye of God and it’s the origin of the All-Seeing Eye on the Great Seal. The Pythagoreans used the circumpunct as the symbol of the Monad — the Divine Truth, the Prisca Sapientia, the at-one-ment of mind and soul, and the —”

“Enough!” Dean Galloway was chuckling now. “Professor, thank you. You are correct, of course.”

Langdon now realized he had just been played. He knew all that.

“The circumpunct,” Galloway said, still smiling to himself, “is essentially the symbol of the Ancient Mysteries. For this reason, I would suggest that its presence in this box is not mere coincidence. Legend holds that the secrets of this map are hidden in the smallest of details.”

“Fine,” Katherine said, “but even if this symbol was inscribed there intentionally, it doesn’t bring us any closer to deciphering the map, does it?”

“You mentioned earlier that the wax seal you broke was embossed with Peter’s ring?”

“That’s correct.”

“And you said you have that ring with you?”

“I do.” Langdon reached into his pocket, found the ring, took it out of the plastic bag, and placed it on the desk in front of the dean.

Galloway picked up the ring and began feeling its surfaces. “This unique ring was created at the same time as the Masonic Pyramid, and traditionally, it is worn by the Mason in charge of protecting the pyramid. Tonight, when I felt the tiny circumpunct on the bottom of the stone box, I realized that the ring is, in fact, part of the symbolon.”

“It is?”

“I’m certain of it. Peter is my closest friend, and he wore this ring for many years. I am quite familiar with it.” He handed the ring to Langdon. “See for yourself.”

Langdon took the ring and examined it, running his fingers over the double-headed phoenix, the number 33, the words ORDO AB CHAO, and also the words All is revealed at the thirty-third degree. He felt nothing helpful. Then, as his fingers traced down around the outside of the band, he stopped short. Startled, he turned the ring over and eyed the very bottom of its band.

“Did you find it?” Galloway said.

“I think so, yes!” Langdon said.

Katherine slid her chair closer. “What?”

“The degree sign on the band,” Langdon said, showing her. “It’s so small that you don’t really notice it with your eyes, but if you feel it, you can tell it’s actually indented — like a tiny circular incision.” The degree sign was centered on the bottom of the band. and admittedly looked to be the same size as the raised nubbin in the bottom of the cube.

“Is it the same size?” Katherine moved closer still, sounding excited now.

“There’s one way to find out.” He took the ring and lowered it into the box, aligning the two tiny circles. As he pushed down, the raised circle on the box slid into the ring’s opening, and there was a faint but decisive click.

They all jumped.

Langdon waited, but nothing happened.

“What was that?!” the priest said.

“Nothing,” Katherine replied. “The ring locked into place. but nothing else happened.”

“No great transformation?” Galloway looked puzzled.

We’re not done, Langdon realized, gazing down at the ring’s embossed insignia — a double-headed phoenix and the number 33. All is revealed at the thirty-third degree. His mind filled with thoughts of Pythagoras, sacred geometry, and angles; he wondered if perhaps degrees had a mathematical meaning.

Slowly, heart beating faster now, he reached down and grasped the ring, which was affixed to the base of the cube. Then, slowly, he began turning the ring to the right. All is revealed at the thirty-third degree.

He turned the ring ten degrees. twenty degrees. thirty degrees —
