Langdon couldn’t help but smile. He still couldn’t fathom that he was standing in this room.
"Follow me," Langdon said. He started briskly down the first aisle, examining the indicator tabs of each vault. "Remember how I told you about the Path of Illumination? How the Illuminati recruited new members using an elaborate test?"

"The challenge the Illuminati had was that after they placed the markers, they needed some way to tell the scientific community the path existed."
"Logical," Vittoria said. "Otherwise nobody would know to look for it."

"As you probably know," Langdon said, "despite Galileo’s compromise,
"No good deed goes unpunished."
Langdon smiled. "So true. And yet Galileo was persistent. While under house arrest, he secretly wrote a lesser-known manuscript that scholars often confuse with
