Buddha. After all, the Greeks had settled here even earlier, in the third century BCE. Other examples, before being blown up in 2001, were the huge images of Buddha carved out of the cliff in Bamiyan, Afghanistan, with their moulded mud and stucco draperies. Alexander's forays and settlements to lands well to the east of his Macedonian homeland remind us that several of the cities that Tucker describes were far more ancient than the Silk Road. Babylon, which fell to Alexander in 331 BCE, had already by then been the Middle East's most magnificent city for over fifteen hundred years. The earliest city to occupy the site of Chang'an was in existence before 1000 BCE.
Tucker manages to convey a huge sweep of history and geography. You will need time to read this book as, if you merely dip into it, you will lose the interconnecting threads, which are the crux of his thesis, i.e. that, throughout fifteen hundred years, numerous cultures met along the Silk Road and nourished each other's creative spirits. You will need to read it at a table because it is too heavy to read on your knees. And you will need an atlas alongside it that has maps showing some realms not often shown on a single spread. Your maps will need to show the geographical proximity of the towering mountain ranges of the Pamirs and the Hindu Kush with the drainage basins of the Aral Sea to their west and north and with the upper tributaries of the Indus to their east and south. The passes connecting these regions beckoned both Alexander and, nearly two thousand years later, Tamerlane, both intent on conquering and settling the north of the Indian subcontinent. You will need a single map to show the vast latitudinal spread of the great grasslands, deserts and semi-deserts from Turkey to northern China over which the nomads galloped. It was along these northernmost routes of the Silk Road that the Mongols charged on their terrifying way to Vienna, besieging it in 1241 and only withdrawing because they had to travel back, unexpectedly but unavoidably, all the way to Karakorum to appoint a new Grand Khan. The Silk Road saw many such events that were turning points in history, such as when in 1218 the governor of a city in what is now Kazakhstan killed an envoy of Ghengis Khan, suspecting that he was a spy, an action that precipitated the wrath of the Khan, and "was to propel the world into an abyss, setting in motion a chain of events that would lead to the deaths of millions of people from the Danube to the Sea of Japan' (p.221) - because Ghengis Khan's horsemen set out to avenge this insult, inflicting terrible retribution on all in their path.
