“Hmm,” she repeated. “ForDisc puts him at one hundred seventy-five centimeters—nearly five nine.”
“That’s odd. Really odd.” Could my tape measure be off—by four full inches? I stepped back and took another look at the skeleton. Suddenly I was struck by how unusual the proportions were—an anomaly I’d registered subconsciously but had failed to appreciate fully. “Look how long of limb and short of trunk he is,” I said to Miranda and Stefan. “This guy was like a human stork.” ForDisc estimated stature by extrapolating from femur and tibia length, and normally that formula was quite accurate. But the formula was fooled by a leggy guy like this—a reminder that it’s the exceptions and outliers that make life interesting and keep science challenging.
The software was also handicapped by the age—or rather the youth—of its data. ForDisc knew nineteenth-and twentieth-century skeletons well—especially modern white Americans—but ancient bones were terra incognita to it. And so, like us, ForDisc didn’t know if our guy was first century or fourteenth, if he was Palestinian or Parisian.
“Well, rats,” said Miranda. “I want a ForDisc upgrade. One that has time-travel and crystal-ball features.”
I was disappointed, too, but Stefan seemed unfazed. “No problem. Let’s get the samples for the C-14 test. That’s the big question anyway: How old are the bones—seven hundred years or two thousand?” He turned to me. “Do you prefer to be a dentist or a bone surgeon? I brought a saw if you want to cut a cross section from the femur.”
“Dentist,” I said. “Pulling teeth is easier. Besides, it doesn’t fill the air with bone dust. Or with plague spores. What if this guy had the plague—wasn’t there an epidemic here in the fourteenth century?” Miranda nodded. “So shouldn’t we be worried? Shouldn’t we be wearing masks?”
“Yes, but no,” said Miranda. “It was really bad here. An infected ship anchored at Marseilles in January of 1348, and the rats swam ashore. Plague hit Avignon two weeks later. Within a matter of months, two-thirds of the people were dead—twenty, thirty thousand people. Corpses rotting in the streets, choking the river.”
“Terrible,” I said. “Must have been terrifying, too.”
“A lot of people blamed the Jews,” she went on. “All over Europe, Jews were driven from cities. Entire Jewish settlements were massacred. Horrific. But here, the pope at the time of the plague—Clement the Sixth—defended the Jews, said they weren’t to blame. He even offered them refuge.”
“That took guts,” I said. “The townspeople could’ve turned on him.”
“No kidding,” she agreed. “What’s the old saying? ‘The friend of my scapegoat is my scapegoat’? But plague doesn’t make hibernating time-bomb endospores the way some other bacteria do.”
“And you know this how?” I pressed.
“I studied up on the way over last week—journal articles on plague were my in-flight entertainment.” Despite my lingering annoyance about the unpleasant turn the dinner-table conversation had taken, I gave her a grudging half smile for that. “In London,” she added, “a team of scientists is trying to reconstruct the entire DNA sequence of the plague bacterium. They’re getting snippets from known plague victims—bones from a fourteenth-century plague cemetery—but they’re having a hard time piecing the genome together. Bottom line? Plague doesn’t survive for centuries, and this guy’s not contagious.”
“Okay, okay, I’m convinced. But I’d still rather pull a tooth than butcher a bone.”
“Let’s send a molar,” Stefan suggested.
Holding the mandible with my left hand, I gripped one of the eighteen-year molars, a wisdom tooth, pinching it firmly between my right thumb and forefinger. I wiggled it gently and felt a slight grating as the tooth wobbled in the dry socket. Wiggling a bit harder, I began to tug, and with a rasp and a faint crunch, it pulled free of the jaw. “What do you think?” I asked, holding out the tooth for Miranda and Stefan to inspect. “First century or fourteenth?”
Miranda weighed in first. “I say it’s him. With a capital H: Him.”
“Jesus? Really?” I pointed toward the fringe of osteoarthritis on the spine. “But he’s ancient,” I reminded her. “My age; maybe older.”
“Nah, not older,” she shot back. “Just harder working. Wore out his spine.”
“You surprise me, Miranda. I had you pegged as a doubter.”
She shrugged. “Sometimes I like to play the long shot. Makes life more interesting.”
I looked at Stefan. “What about you? How do you vote?”
He shrugged, looking bored. “Oh, of course it would be interesting if Miranda was right, but that’s unlikely. I think probably fourteenth century.” He said it in a monotone, but his eyes flickered, and I wondered if he was more hopeful than he was admitting.
