Ancient Chinese documents dating back 1600 years have revealed the presence of Romans at the very heart of China as far back as the year 166 AD. According to these chronicles, they had been emissaries sent by the powers in Rome in order to establish relations with the Han Empire. Were they ambassadors or just ordinary merchants ? Maybe they were both… At the times of Augustus, Rome’s first emperor, the empire had been enjoying two prosperous centuries. It was the era of the Pax Romana and Rome’s power was to expand rapidly due to contacts and trade. Endless caravans supplied a steady stream of goods from the Orient to the ports of the Mediterranean. Each trip represented a perilous voyage of 11 000 km with dangers lurking along the trade routes, not least of them being the Huns who turned travelling into a dangerous and uncertain enterprise.
