The old dean placed his hands reverently around the sides of the Masonic Pyramid and spoke very quietly. «My friends, I do not know exactly
«Father,» Langdon said, his tone challenging, «we’re all familiar with the Revelation of Saint John and the literal meaning of the Apocalypse, but biblical prophecy hardly seems — »
«Oh, heavens, the Book of Revelation is a mess!» the dean said. «Nobody knows how to read that. I’m talking about
«It’s a safe prediction to make,» Langdon said. «Knowledge grows exponentially. The more we know, the greater our ability to learn, and the
«Yes,» Katherine added. «We see this in science all the time. Each new technology we invent becomes a tool with which to invent new technologies. . and it snowballs. That’s why science has advanced more in the last five years than in the previous five
Silence fell in the dean’s office, and Galloway sensed that his two guests still had no idea how this pyramid could possibly help them reveal anything further.
For many years, the Reverend Colin Galloway, along with his Masonic brothers, had played the role of gatekeeper. Now it was all changing.
«professor langdon?» galloway said, reaching out across his desk. «take my hand if you will.»
Robert Langdon felt uncertain as he stared across at Dean Galloway’s outstretched palm.
Politely, Langdon reached out and placed his right hand in the dean’s withered hand. The old man grasped it firmly but did not begin to pray. Instead, he found Langdon’s index finger and guided it downward into the stone box that had once housed the golden capstone.
«Your eyes have blinded you,» the dean said. «If you saw with your fingertips as I do, you would realize this box has something left to teach you.»
Dutifully, Langdon worked his fingertip around the inside of the box, but he felt nothing. The inside was perfectly smooth.
«Keep looking,» Galloway prompted.
Finally, Langdon’s fingertip felt something — a tiny raised circle — a minuscule dot in the center of the base of the box. He removed his hand and peered inside. The little circle was virtually invisible to the naked eye.
«Do you recognize that symbol?» Galloway asked.
«Symbol?» Langdon replied. «I can barely see anything at all.»
«Push down on it.»
Langdon did as he asked, pressing his fingertip down onto the spot.
«Hold your finger down,» the dean said. «Apply pressure.»
Langdon glanced over at Katherine, who looked puzzled as she tucked a wisp of hair behind her ears.
A few seconds later, the old dean finally nodded. «Okay, remove your hand. The alchemy is complete.»
«Nothing,» Langdon said.
«Look at your fingertip,» the dean replied. «You should see a transformation.»
Langdon looked at his finger, but the only transformation he could see was that he now had an indentation on his skin made by the circular nubbin — a tiny circle with a dot in the middle.

«
Although Langdon recognized the symbol, he was more impressed that the dean had been able to feel the detail of it. Seeing with one’s fingertips was apparently a learned skill.
«It’s alchemical,» Katherine said, sliding her chair closer and examining Langdon’s finger. «It’s the ancient symbol for
«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
«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
«Enough!» Dean Galloway was chuckling now. «Professor, thank you. You are correct, of course.»
Langdon now realized he had just been played.
«The circumpunct,» Galloway said, still smiling to himself, «is essentially
«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
«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
