cuneiform tablets inscribed with the same characters she’d deciphered in the cave; ancient tools from the early Bronze Age, including an axe, chisels, hammers and knives. ‘Are these reproductions?’ she asked Stokes.
‘All originals,’ he said like a proud father. He looked back to the door. ‘Will you be joining us, Agent Flaherty?’
‘Just taking it all in,’ Flaherty said, and made his way over in small steps. The smooth soles of his loafers caught the slick surface of a wide swath of carpet in the room’s centre. A trace of chemicals wafted up into his nostrils. Cleaning solution. The area had been scrubbed very recently. Flaherty had a sneaking suspicion as to why.
‘Oh wow,’ Brooke muttered. She stared in wonderment at the huge monolith carved in bas-relief with two winged Mesopotamian protective spirits, or
‘No. That was the seal that we removed from the cave entrance.’
‘Really.’ She quickly tabulated that it predated Babylonian works by at least fourteen centuries. Ye t its quality was equally stunning. ‘It’s magnificent.’
‘Indeed. Even more impressive than what came centuries after it. Just like the writing you transcribed for us - far more sophisticated than anyone ever expected.’
In the obelisk-shaped display case next to the seal, Brooke spotted a highly unusual clay tablet etched not only in writing, but schematic designs. ‘This text … these images,’ she said in awe. ‘Is this what I think it is?’
Stokes nodded. ‘The world’s oldest map. Given to me by a dear friend.’
For a long moment, Stokes stared at the artifact. More than anything, this keepsake symbolized the incredible spiritual transformation he’d undergone after the monks had found him disfigured on the roadside all those years ago.
In the sanctuary of a hilltop monastery, it had been Monsignor Ibrahim himself who’d overseen Stokes’s physical and spiritual rehabilitation. The monsignor had brought Stokes to the looming mountain that marked Lilith’s ancient tomb and imparted to him a haunting tale of civilization’s first Apocalypse that transformed what had once been a lush paradise. By torchlight, they’d stood side by side in the cave’s entry passage as the monsignor recounted Lilith’s journey, immortalized in stone. He’d shown Stokes the chamber where Lilith’s victims had been buried en masse. Then he’d brought Stokes to the demon’s tomb, deep inside the mountain.
‘Like you, Lilith’s bold venture into the unknown realm had not been in vain,’ Monsignor Ibrahim had told him. ‘Her predestined journey merely marked the beginning for many changes yet to come. Everything you need is here. Now it is time for your destiny to begin.’
And from that humble beginning - that tiny mustard seed - sprang Operation Genesis.
Stokes punched a code into the base of the display case, then unhinged the lid. He removed the tablet, admired it and offered it to her.
‘A map for what place?’ Brooke asked as she cautiously accepted the tablet.
‘That, Ms Thompson, is the map to what later mythology would call Eden. A treasure map that points to the beginning of humanity and civilization. A thriving city in the northern mountains of ancient Mesopotamia. It is how we found the cave.’
Once again, Brooke was overcome by wonder.
‘You can see here,’ Stokes said, ‘the river that once led to the Zagros Mountains. But the real clues are written here.’ He indicated the wedge-shaped symbols.
The way the symbols repeated suggested to Brooke that it was a numbering system. If so, the established timeline of recorded history had again been turned upside down. The earliest known numeral system had been developed in southern Mesopotamia in 2000 BC by the Sumerians - a sexagesimal system that used the number sixty as its base (with ten as a subbase). With sixty being the smallest number divisible by every factor from one to six, it could easily be separated into halves, thirds and quarters. Thus it simplified common measurements, such as time, geometric angles and geographic coordinates. The Sumerians annotated numbers one through nine with Y- shaped wedges (e.g., three: ‘YYY’, six: ‘YYYYYY’), and tens were sideways Vs that looked like less-than signs (e.g., twenty: ‘<<’, fifty: ‘<<<<<’).
What appeared on this tablet looked much different - much more sophisticated than the Sumerian numbering system. ‘These are numbers?’ Brooke said.
‘Yes. Geographic coordinates based on astrological measurements,’ Stokes said. ‘Ingenious for its time.’
‘Is that possible, Brooke?’ Flaherty asked.
She considered it, then nodded. ‘The Mesopotamians were obsessed with the celestial cycles. So I’d say, yes.’ But without fully transcribing and testing the number system she had to accept what Stokes was saying. ‘And this was what led you to the cave?’ she asked Stokes.
‘Yes.’
If he’d truly been able to decipher this tablet, she thought, then why would he have commissioned her - an outsider - to assist in the excavation? It didn’t add up.
Flaherty was losing his patience. ‘This is all very nice, Stokes. But let’s talk about the other things you found in the cave. The real reason behind your excavation. We know about the skeletons. So why did you study all their teeth?’
‘Yes, the teeth,’ Stokes said. He reflected for a moment to choose his starting point. He directed his response to Brooke. ‘As you know, the emergence of civilization was long, uneven, violent, and marked by many false starts and setbacks. And every major turning point … every conquest in history, was determined by nature’s most potent equalizer: disease. Pestilence is the planet’s survival mechanism. The means not only for maintaining equilibrium, but for genetically selecting winners and losers.’
Flaherty said, ‘I thought guys like you didn’t believe in evolution?’
‘Creationism may make for good sermons, but it certainly doesn’t make good sense or good science,’ Stokes admitted. ‘Ms Thompson, the story you deciphered on the wall of that cave chronicled one of the most profound events that shaped modern civilization. It told of a thriving, technologically advanced people who’d effectively been wiped out shortly after the arrival of a foreign visitor.’
‘Lilith,’ Brooke said.
‘That’s one of the names later mythology ascribes to her,’ he conceded. ‘Lilith was responsible for a wholesale extermination at the dawn of the earliest civilization. A theme that would play out many, many more times throughout our history.’
‘But only the males died, right?’ Brooke said.
Stokes raised his eyebrows. ‘Every one of them. Which begged the question: how could pestilence selectively afflict only men? It seemed impossible. But the remains found in that cave substantiate the story. At that time Frank Roselli was overseeing Fort Detrick’s Infectious Disease lab. His top virologists and geneticists studied specimens from the cave - traces of ancient DNA left behind from a most unusual virus. Of course, I’m not a scientist,’ Stokes said, ‘so the nuances are lost on me. However, I do understand the basic mechanics.’ He paused to marshal his thoughts. ‘The majority of conventional viruses are coded in RNA and replicate within the cytoplasm of host cells. But some viruses, like Lilith’s plague, are coded in DNA and penetrate deeper into the host cell’s nuclear core to replicate.’
Roselli had explained to him how the nucleus of human cells stores the entire genetic code - the genome. The genome has twenty-three chromosome pairs, twenty-two non-sex chromosomes, and one pair of sex chromosomes. The female sex chromosome is noted as ‘XX’ and the male’s is ‘XY.’ At the genetic level all humans are 99.9 per cent identical. Mutations passed on from one generation to the next make up the remaining 0.1 per cent of the genetic code. These ‘single nucleotide polymorphisms’ recode one of the four nucleotides - adenine (A), cytosine (C), guanine (G) and thymine (T) - along the gene, changing an ‘A’ to a ‘C’ or a ‘G’ to a ‘T’. And in those slight mutations, ancestry can be traced back along a 100,000-year genetic tree to one man and one woman in Africa - the genetic Adam and genetic Eve. ‘Which means we’re all distant cousins,’ Roselli had explained. Roselli inevitably sided with science by refuting the notion of a truly common variant among any ethnic group. Yet Roselli’s scientists clearly demonstrated that a high frequency of specific genetic variations were common among different ethnic groups.
Stokes’s interpretation of the genetic data was simple: the Middle East was a hotbed of genetic variation, and Lilith’s plague was capable of pinpointing the specific genetic sequences that accounted for it.
