A few moments later he was back outside with a map of Europe which he unrolled and pinned down on the patio table using their coffee mugs. Costas drew his chair up as Jack swept his hand from Scandinavia to the Black Sea.
“The Byzantines called them Varangians,” Jack said. “Tall, blond, terrifying barbarians from the north who served as mercenaries in the Byzantine emperor’s legendary Varangian Guard, the successor of the Praetorian Guard of ancient Rome. In Hardrada’s day the Varangian Guard were mainly Vikings, Norse warriors from Scandinavia whose behaviour fully justified their reputation. They pillaged and burned their way around the Mediterranean, thinly disguised as standard-bearers for the Christian emperor but in reality pagan heroes who returned to their homelands in the north full of tales of bloodlust and booty. By the time they were wiped out by the Crusaders during the Sack of Constantinople in 1204, many of the Guard were English, descendants of Anglo-Saxon warriors who had fled England following the Battle of Hastings in 1066 when William of Normandy defeated King Harold of England.”
“You mean the other Harold?” Costas queried.
Jack nodded. “There was Viking blood in all the contestants to the English throne in 1066. The Normans were north-men, descendants of Vikings who had settled in France the century before. King Harold of England’s Anglo-Saxon ancestors were themselves migrants from Denmark and northern Germany. But the only thoroughbred Viking among the contestants in 1066 was Harald Hardrada, King of Norway. He was the most feared of them all, and had learned his trade decades earlier as chief of the Varangian Guard in Constantinople.”
Costas measured the distance with his hand and shook his head. “That’s over two thousand miles from Norway.”
“Just as the Vikings were beginning to explore west, to the British Isles and beyond, they were also going east,” Jack explained. “From as early as the eighth-century AD Scandinavian traders were penetrating the rivers of central and eastern Europe, from the Vistula on the Baltic to the Dnieper on the Black Sea. They were seeking untold wealth, the fabled treasures of the Orient, a hunt for silver and precious stones that took them to Central Asia and deep into the world of Islam. Eventually they founded the Viking kingdom of Rus, the origin of modern Russia. From their stronghold at Kiev they were within striking distance of the place they called Michelgard, the Great City, a perilous journey down the Dnieper but the key to riches beyond their dreams.”
“That’s how they got to Constantinople?” Costas said.
Jack smiled. “It’s true. If you don’t believe it, you only have to look at Viking treasure hoards discovered in their Scandinavian homeland, full of Arab silver coins which the Vikings acquired in exchange for furs and slaves and amber.”
Jack could see Costas looking dubiously at the distance between Norway and present-day Istanbul. “If you still need convincing, take a look at this.” Jack handed him a black-and-white photograph showing a polished marble railing, its surface covered with ancient graffiti. “Those linear symbols on the edge? They’re runes, Viking letters, probably eleventh century. They’re too worn to decipher completely, but a name can be made out: ‘Halfdan was here,’ or something like that. Any guesses where it is? Thousands of tourists pass within touching distance of it every year. It’s in an alcove high above the nave of Hagia Sofia, in the heart of ancient Constantinople. Halfdan was almost certainly one of the Varangian bodyguard, and given the date, he could even have been one of Harald Hardrada’s men.”
As he finished speaking, a thudding noise from the east that had been increasing in volume became a reverberating clatter, and a Lynx helicopter appeared out of the clouds, descending towards the helipad near the shoreline.
“I’ll take your word for it.” Costas grinned and handed back the photograph. “Right now I think we need to greet our guests.”
A few minutes later the two men stood at the edge of the helipad as the twin Rolls-Royce Gem turboshafts powered down and the main rotor of the Lynx shuddered to a halt. The first figure to step out of the passenger compartment was a strikingly attractive woman wearing a leather jacket and jeans, her long brown hair swept back into a loose bun. Maria de Montijo was one of Jack’s oldest friends, part of a close-knit group including Maurice Hiebermeyer and Efram Jacobovich who had first met as students at Cambridge. Maria and Jack had helped each other through difficult times and had forged a close bond. He had involved her in the Golden Horn project from the outset, and it made sense that he was the first person she would call with news of the astonishing discovery in Hereford Cathedral.
Maria’s dark Spanish features creased into a smile as she embraced Jack and Costas in turn. “Jack, you’ve met Jeremy, my American graduate student.” The tall young man who loped behind Maria swept his blond hair from his face and proffered his hand. They had met several weeks earlier when Jack had visited the Institute of Medieval Studies in Oxford to have a translation made of the newly discovered Topkapi manuscript, the eyewitness account of the Crusader siege of Constantinople that contained the crucial position-fix for the chain across the harbour. Jack had been impressed by Jeremy’s facility with the medieval Greek, and had no reason to doubt Maria’s enthusiastic judgement of his potential.
“How long have you been out of the States?” Costas asked amiably.
“Three years.” Jeremy peered down at the shorter man through his glasses. “I’ve got a fellowship waiting for me at Princeton, but I just don’t seem to be able to get away from this place.”
“I know the problem,” Costas said. “I keep trying, but every time I do he finds some reason to keep me here.” He jerked his head towards Jack and grinned. “Luckily, working for an international outfit means I’m not trapped in English drizzle all year long.”
“Gentlemen, allow me to introduce Father Patrick O’Connor.” Maria gestured towards the helicopter, and they turned to watch the figure being helped down by the pilot. In startling contrast to the flight suit and helmet of the crewman, he was wearing the distinctive black cassock of a Jesuit priest and was carrying two battered leather briefcases.
After nodding to the pilot, he strode confidently across the helipad, dropped his cases on the tarmac and shook Jack’s hand firmly. “Dr. Howard. Delighted to meet you at last. Maria’s told me all about you, and of course I’ve seen you on TV following your remarkable discoveries last year.”
Jack eyed the other man keenly. The accent had a hint of Irish brogue, but could as easily have been Boston. He guessed that O’Connor was a youthful fifty-five, his remaining hair grey and cropped close but with the weathered face and fit body of a man who had not spent his entire life in the cloisters.
“Maria tells me you have a PhD in early Church history,” Jack said.
“Trinity College, Dublin, then Heidelberg,” O’Connor replied. “Then I found my vocation. Twenty years in Central America, mainly Mexico, doing what we Jesuits do best, building schools, ministering to the sick, trying to bring humanity to places where there’s sometimes hardly any left at all.”
“And then you found academia again.”
O’Connor nodded. “Five years ago. I’d done my tour of duty and applied for a vacancy in the Vatican library. To my delight they offered me a tailor-made position in the Antiquities Department, as inspector of early buildings and archaeology. My remit covers everything in Rome under Vatican control up to the time of the Renaissance, with plenty of time for my own research. I was in Oxford to hear Maria’s seminar on Richard of Holdingham and the Mappa Mundi, one of my special areas of interest. I believe I may have something to offer.”
