'The others have had the benefit of several weeks to examine this photo,' de l'Orme explained. 'It's a route map known as the Peutinger Table. Twenty-one feet long by one foot high in the original. It details a medieval network of roads seventy thousand miles long that ran from the British Isles to India. Along the road were stage stops, spas, bridges, rivers, and seas. Latitude and longitude were irrelevant. The road itself was everything.'
The archaeologist paused. 'I had asked you all to try to find anything out of the ordinary on the photo. I particularly directed your attention to the Latin phrase 'Here be dragons,' midcenter on the map. Did anyone notice anything unusual in that region?'
'It's seven-thirty in the morning,' someone said. 'Please teach us our lesson so we may eat our breakfast.'
'If you please,' de l'Orme said to his aide.
Santos lifted a wooden box onto the table, brought out from it a thick scroll, and began to unroll it delicately. 'Here is the original table,' said de l'Orme. 'It is housed here in the museum.'
'This is why we were brought to New York?' complained Parsifal.
'Please, compare for yourselves,' said de l'Orme. 'As you can see, the photo duplicates the original at a scale of one-to-one. What I wish to demonstrate is that seeing is not believing. Santos?'
The young man drew on a pair of latex gloves, produced a surgical scalpel, and bent over the original.
'What are you doing?' an emaciated man squeaked in alarm. His name was Gault, and Ali would later learn that he was an encyclopedist of the old Diderot school, which believed that all things could be known and arranged alphabetically. 'That map is irreplaceable,' he protested.
'It's all right,' de l'Orme said. 'He's simply exposing an incision we've already made.' The excitement of an act of vandalism in front of their eyes woke them up. Everyone came close to the table. 'It is a secret the cartographer built into his map,' de l'Orme said. 'A well-kept secret. If not for a blind man's bare fingertips, it might never have been discovered. There is something quite wicked about our reverence for antiquity. We've come to treat the thing itself with such care that it has lost its original truth.'
'But what's this?' someone gasped.
Santos was inserting his scalpel into the parchment where the cartographer had painted a small forested mountain with a river issuing from its base.
'Because of my blindness, I'm allowed certain dispensations,' de l'Orme said. 'I touch things most other people may not. Several months ago, I felt a slight bump at this place on the map. We had the parchment X-rayed, and there seemed to be a ghost image underneath the pigment. At that point we performed surgery.'
Santos opened a tiny hidden door. The mountain lifted upon hinges made of thread. Underneath lay a crude but coherent dragon. Its claws embraced the letter B.
'The B stands for Beliar,' said de l'Orme. 'Latin for "Worthless." Another name for Satan. This was the manifestation of Satan concurrent with the making of the Peutinger Table. In the Gospel of Bartholomew, a third-century tract, Beliar is dragged up from the depths and interrogated. He gives an autobiography of the fallen angel.'
The scholars marveled at the mapmaker's ingenuity and craft. They congratulated de l'Orme on his detective work.
'This is insignificant. Trivial. The mountain on this doorway lies in the karst country of the former Yugoslavia. The river coming from its base is probably the Pivka, which emerges from a Slovenian cave known today as Postojna Jama.'
'The Postojna Jama?' Gault barked in recognition. 'But that was Dante's cave.'
'Yes,' said de l'Orme, and let Gault tell them himself.
'It's a large cave,' Gault explained. 'It became a famous tourist attraction in the thirteenth century. Nobles and landowners would tour with local guides. Dante visited while researching –'
'My God,' said Mustafah. 'For a thousand years the legend of Satan was located right here. But how can you call this trivial?'
'Because it leads us nowhere we've not already been,' said de l'Orme. 'The Postojna Jama is now a major portal for traffic going in and out of the abyss. The river has been dynamited. An asphalt road leads into the mouth. And the dragon has fled. For a thousand years this map told us where he once resided, or possibly where one of his doorways into the subplanet lay. But now Satan has gone elsewhere.'
Thomas took over again.
