Sienna nodded politely and kept moving, her eyes also straight ahead. Marta was barely able to keep pace. As they reached the third room, she had fallen behind a bit and finally stopped short.
“Professor?” she called out, panting. “Perhaps you … want to show your sister … some of the gallery … before we see his mask?”
Langdon turned, seeming distracted, as if returning to the present from some far-off thought. “Excuse me?”
Marta breathlessly pointed to a nearby display case. “One of the earliest … printed copies of The Divine Comedy?”
When Langdon finally saw Marta dabbing her forehead and trying to catch her breath, he looked mortified. “Marta, forgive me! Of course, yes, a quick glance at the text would be wonderful.”
Langdon hurried back, permitting Marta to guide them over to the antique case. Inside was a well-worn, leather-bound book, propped open to an ornate title page: La Divina Commedia: Dante Alighieri.
“Incredible,” Langdon said, sounding surprised. “I recognize the frontispiece. I didn’t know you had one of the original Numeister editions.”
Of course you knew, Marta thought, puzzled. I showed this to you last night!
“In the mid–fourteen hundreds,” Langdon said hurriedly to Sienna, “Johann Numeister created the first printed edition of this work. Several hundred copies were printed, but only about a dozen survived. They’re very rare.”
It now seemed to Marta that Langdon had been playing dumb so he could show off for his younger sibling. It seemed a rather unbecoming immodesty for a professor whose reputation was one of academic humility.
“This copy is on loan from the Laurentian Library,” Marta offered. “If you and Robert have not visited there, you should. They have a spectacular staircase designed by Michelangelo, which leads up to the world’s first public reading room. The books there were actually chained to the seats so nobody could take them out. Of course, many of the books were the only copies in the world.”
“Amazing,” Sienna said, glancing deeper into the museum. “And the mask is this way?”
What’s the hurry? Marta needed another minute to regain her breath. “Yes, but you might be interested to hear about this.” She pointed across an alcove toward a small staircase that disappeared into the ceiling. “That goes up to a viewing platform in the rafters where you can actually look down on Vasari’s famous hanging ceiling. I’d be happy to wait here if you’d like to—”
“Please, Marta,” Sienna interjected. “I’d love to see the mask. We’re a little short on time.”
Marta stared at the pretty, young woman, perplexed. She very much disliked the new fashion of strangers calling each other by their first names. I’m Signora Alvarez, she silently chided. And I’m doing you a favor.
“Okay, Sienna,” Marta said curtly. “The mask is right this way.”
Marta wasted no more time offering Langdon and his sister informed commentary as they made their way through the winding suite of gallery rooms toward the mask. Last night, Langdon and il Duomino had spent nearly a half hour in the narrow andito, viewing the mask. Marta, intrigued by the men’s curiosity for the piece, had asked if their fascination was related somehow to the unusual series of events surrounding the mask over this past year. Langdon and il Duomino had been coy, offering no real answer.
Now, as they approached the andito, Langdon began explaining to his sister the simple process used to create a death mask. His description, Marta was pleased to hear, was perfectly accurate, unlike his bogus claim that he had not previously seen the museum’s rare copy of The Divine Comedy.
“Shortly after death,” Langdon described, “the deceased is laid out, and his face is coated with olive oil. Then a layer of wet plaster is caked onto the skin, covering everything—mouth, nose, eyelids—from the hairline down to the neck. Once hardened, the plaster is easily lifted off and used as a mold into which fresh plaster is poured. This plaster hardens into a perfectly detailed replica of the deceased’s face. The practice was particularly widespread in commemorating eminent persons and men of genius—Dante, Shakespeare, Voltaire, Tasso, Keats—they all had death masks made.”
“And here we are at last,” Marta announced as the trio arrived outside the andito. She stepped aside and motioned for Langdon’s sister to enter first. “The mask is in the display case against the wall on your left. We ask that you please stay outside the stanchions.”
“Thank you.” Sienna entered the narrow corridor, walked toward the display case, and peered inside. Her eyes instantly went wide, and she
