Inferno: (Robert Langdon Book 4)

waiting to greet them. Upon seeing Mirsat, the guards unlocked one of the doors and swung it open.
    “Sağ olun,” Mirsat said, uttering one of a handful of Turkish phrases Langdon was familiar with—an especially polite form of “thank you.”
    The group stepped through, and the guards closed the heavy doors behind them, the thud resonating through the stone interior.
    Langdon and the others were now standing in Hagia Sophia’s narthex—anarrow antechamber that was common in Christian churches and served as an architectural buffer between the divine and the profane.
    Spiritual moats , Langdon often called them.
    The group crossed toward another set of doors, and Mirsat pulled one open. Beyond it, instead of the sanctuary he had anticipated seeing, Langdon beheld a secondary narthex, slightly larger than the first.
    An esonarthex , Langdon realized, having forgotten that Hagia Sophia’s sanctuary enjoyed two levels of protection from the outside world.
    As if to prepare the visitor for what lay ahead, the esonarthex was significantly more ornate than the narthex, its walls made of burnished stone that glowed in the light of elegant chandeliers. On the far side of the serene space stood four doors, above which were spectacular mosaics, which Langdon found himself intently admiring.
    Mirsat walked to the largest door—a colossal, bronze-plated portal. “The Imperial Doorway,” Mirsat whispered, his voice almost giddy with enthusiasm. “In Byzantine times, this door was reserved for sole use of the emperor. Tourists don’t usually go through it, but this is a special night.”
    Mirsat reached for the door, but paused. “Before we enter,” he whispered, “let me ask, is there something in particular you would like to see inside?”
    Langdon, Sinskey, and Brüder all glanced at one another.
    “Yes,” Langdon said. “There’s so much to see, of course, but if we could, we’d like to begin with the tomb of Enrico Dandolo.”
    Mirsat cocked his head as if he had misunderstood. “I’m sorry? You want to see … Dandolo’s tomb?”
    “We do.”
    Mirsat looked downcast. “But, sir … Dandolo’s tomb is very plain. No symbols at all. Not our finest offering.”
    “I realize that,” Langdon said politely. “All the same, we’d be most grateful if you could take us to it.”
    Mirsat studied Langdon a long moment, and then his eyes drifted upward to the mosaic directly over the door, which Langdon had just been admiring. The mosaic was a ninth-century image of the Pantocrator Christ—the iconic image of Christ holding the New Testament in his left hand while making a blessing with his right.
    Then, as if a light had suddenly dawned for their guide, the corners of Mirsat’s lips curled into a knowing smile, and he began wagging his finger. “Clever man! Very clever!”
    Langdon stared. “I’m sorry?”
    “Don’t worry, Professor,” Mirsat said in a conspiratorial whisper. “I won’t tell anyone why you’re really here.”
    Sinskey and Brüder shot Langdon a puzzled look.
    All Langdon could do was shrug as Mirsat heaved open the door and ushered them inside.

CHAPTER 88
    THE EIGHTH WONDER of the World, some had called this space, and standing in it now, Langdon was not about to argue with that assessment.
    As the group stepped across the threshold into the colossal sanctuary, Langdon was reminded that Hagia Sophia required only an instant to impress upon its visitors the sheer magnitude of its proportions.
    So vast was this room that it seemed to dwarf even the great cathedrals of Europe. The staggering force of its enormity was, Langdon knew, partly an illusion, a dramatic side effect of its Byzantine floor plan, with a centralized naos that concentrated all of its interior space in a single square room rather than extending it along the four arms of a cruciform, as was the style adopted in later cathedrals.
    This building is seven hundred years older than Notre-Dame , Langdon thought.
    After taking a moment to absorb the breadth of the room’s dimensions, Langdon let his eyes climb skyward, more than a hundred and fifty feet overhead, to the sprawling, golden dome that crowned the room. From its central point, forty ribs radiated outward like rays of the sun, extending to a circular arcade of forty arched windows. During daylight hours, the light that streamed through these windows reflected—and re-reflected—off glass shards embedded in the golden tile work, creating the “mystical
