During an epic naval battle between Chinese and local forces off the coast of Sri Lanka more than 600 years ago, a massive treasure ship laden with gold, precious gems and religious artefacts was scuppered and sank to the bottom of the Indian Ocean.
According to the history books, the vessel (or vessels – no one knows for sure exactly how many ships might have sunk) was part of the fleet of Chinese admiral Zheng He, one of the greatest maritime adventurers of all time. But while stories of his exploits abound in Chinese texts, no hard evidence has ever been found to prove the existence of his ships.
That, however, could be about to change, as researchers are set to embark on an archaeological expedition that they believe could not only settle a centuries-old debate, but also yield a hoard of lost Ming dynasty (1368-1644) treasure.
