took a microcassette recorder from her bag. ‘You don’t mind, do you?’ she asked.
‘Of course not,’ said Knox.
She nodded at the crane, the metal beginning to groan and shriek a little as it took the weight of the anchor and began lifting it from the sea-bed. ‘And maybe we could go somewhere quieter?’
He led her up a gangway and past the ship’s decompression chamber, leaned against the starboard rail. The wind had picked up; the sea was getting frisky. The ship’s dynamic positioning system had been turned on, however, and its GPS sensors, gyroscopes and thrusters were keeping them impressively steady, a vital capability for using a crane on a sea-bed sixty metres deep. A large wave swept past them to break against the reef. On its far side, he could see the white cotton sails of several fishing pirogues in the lagoon, all of them heading for shore. ‘Better?’ he asked.
‘Perfect,’ said Lucia. ‘You were about to sweep me off to thirteenth-century China.’
‘The time of the Mongol Khans,’ said Knox. ‘Genghis was a conqueror. He rampaged through Russia and China and put the fear of God into Europeans.’ Literally, as it had happened: Christians had feared he and his armies were the end-times prophecy of Gog and Magog made flesh. ‘But his successors were different, particularly his grandson Kublai.’
‘In Xanadu did Kublai Khan a sacred pleasure dome decree,’ suggested Lucia.
‘That’s the guy,’ agreed Knox. ‘He saw himself as a ruler more than a general, and China was the jewel in his crown. He established a new capital at Beijing, tried to win over his new Chinese subjects by appointing them to key positions. But it never really took. The Han and the Mongols each considered the other inferior. And these were tough times anyway. China was hit by the black death almost as badly as Europe, and there was massive flooding, hyperinflation, poverty and famine. The Han began to rebel, as did other ethnic groups. The first uprisings were quashed but each new one weakened the Mongols’ grip a little more until the empire finally collapsed in 1368. One of the rebel leaders, a Han called Zhu Yuanzhang, seized the Dragon Throne and proclaimed himself first emperor of the Great Ming.’
‘That being the start of the Ming Dynasty, presumably?’
‘Yes. Zhu Yuanzhang held power for thirty years or so, but his succession proved a problem. His eldest son, the Crown Prince, died before him, forcing him to pick between his own most capable surviving son—a man called Zhu Di—or to skip a generation and appoint his grandson Zhu Yunwen instead. He went for his grandson.’
‘Don’t tell me: Zhu Di got mad.’
‘It depends on who you believe,’ Knox told her. ‘We know that Zhu Yunwen was worried sick about rivals. After his ascension, he barred Zhu Di from even paying respects to his dead father—a major humiliation—then stripped his supporters of rank, effectively forcing him to give up or fight back. He chose to fight back. Skirmishes with the imperial army turned into a lowlevel civil war. In 1402, Zhu Di marched on Nanjing, China’s new capital, and his nephew fled. Then he declared himself the Yongle Emperor. Emperor of eternal happiness.’
Lucia smiled. ‘No worries about raising expectations, then.’
‘He didn’t do too badly, all in all. He excised his nephew from the history books and purged his supporters; but that was pretty standard. He fought off the Mongols and the Vietnamese, introduced land reclamation and other successful agricultural policies, rebuilt the Grand Canal and moved his capital back to Beijing. He also commissioned a series of magnificent armadas.’
‘Ah. Our famous treasure fleets.’
‘This was unprecedented. The Han Chinese were Confucians; only China mattered. If the barbarian world had business with China, it had to make the journey itself. But Zhu Di didn’t think that way. He wanted to show off, and maybe let it be known around the region that he wasn’t a man to mess with. His nephew was rumoured still to be alive, after all, so the last thing he’d have wanted was any lingering questions about his legitimacy. Whatever his reasons, he ordered a man called Zheng He to build a vast fleet then sail around the China Seas to establish diplomatic and trading links, suppress any unrest in China’s overseas territories, that kind of thing.’
‘Zheng He. This would be the eunuch, right?’
‘Yes. He was actually a Chinese Muslim whose family had fought with the Mongols, and he was taken captive and then castrated when still just a boy. It happened a lot back then. But he made a name for himself, become one of Zhu Di’s favourites.’ Lucia raised an eyebrow, making Knox laugh. ‘Not in that sense,’ he assured her. ‘Zhu Di liked the ladies. Koreans, for choice. But that was precisely why he trusted eunuchs: they wouldn’t cause mischief in his harem, and they had no dynastic ambitions of their own.’
‘Okay. So Mr Eternal Happiness commissions his favourite eunuch to go sailing. And there were multiple voyages, right?’
‘Seven in all, though the final one was much later, more an afterthought than anything. Mostly they visited the places you’d expect: Sumatra and Java and the other main Indonesian islands. Vietnam, Thailand, Sri Lanka, Malaya, India. Places which were pretty well known to the Chinese. Their fourth voyage made it to Arabia and East Africa, but it’s the sixth that’s the most intriguing. Zheng He didn’t actually go very far himself, but various of his vice-admirals each led a contingent of their own, and we’re not entirely sure where they went, not least because there was a great fire in Beijing shortly after they set out, which the emperor interpreted as a divine admonishment against his treasure fleets, so all records of the voyage were destroyed.’
‘And this anchor of yours would have come from this sixth voyage, right?’
‘Most likely,’ agreed Knox. ‘Though Chinese ships were hopeless at sailing against the wind: they pretty much had to go wherever the weather took them. That was fine, most of the time, because the trade winds are very reliable between Africa and China. But if some Chinese ship from one of the other fleets had been blown off course at the wrong time, it might have had little choice except to end up here. And these armadas were huge. There were supposed to be three hundred and seventeen ships in the first voyage alone, carrying over twenty-eight thousand people. Even allowing for some exaggeration, that’s pretty damned impressive. The demand for wood was so intense that they deforested whole regions of China. Most of the ships were supply boats, troop transports, that kind of thing. Others were for cargo, for these were trading missions too, swapping Chinese silks and porcelain for highly prized goods like pearls, ivory and exotic woods. But each fleet also included a number of what were known as treasure ships. These were floating palaces, really; or perhaps more accurately embassies, designed specifically to impress and intimidate foreign powers. They were reputed to be over four hundred feet long and a hundred and eighty feet wide. That’s like floating a football stadium out to sea. This was ninety-odd years before Columbus, yet these beasts were more than twice as wide as the Santa Maria was long. They had nine masts, the tallest of which was said to have stood over three hundred feet high.’
‘Three hundred feet?’ Lucia pulled a face. ‘Is that even possible?’
‘A lot of historians and shipbuilders think not. They say the treasure ships were more likely to have been sixmasters, only about two hundred foot long.’ He gave a little grin, nodded over the side of the ship down towards the sea-bed. ‘But that’s what makes all this so exciting: we won’t know one way or the other until we—’ Cheers and hoots erupted at the stern. He looked around to see that the anchor had just breached the surface of the water, like some great whale coming up for air, streams of seawater cascading from it and the steel cable and the hoist straps at either end as it was slowly raised higher and higher.
‘Wow!’ murmured Lucia, producing a camera from her bag.
‘You want to go closer?’ asked Knox. She nodded eagerly, so he led her back down. The crane arm began to turn, bringing the black and rust-red anchor around over the deck, its cables and straps creaking loudly
