1900 years after she was carved, an Indian ivory statuette was uncovered in the ancient Roman city of Pompeii. How did she come there, and how much had the world changed since the eruption of Vesuvius buried her? This is her story: a story of the globalization of the ancient world, a story of the vast diversity and complexity of the world that our ancestors called home. Episode 4 of Echoes of India looks back on the first three to paint a picture of a planet in flux, as economic webs weave together ancient civilizations in a pattern of interaction and innovation that is strikingly reminiscent of the world we know today. Hear the explosion of Vesuvius, the great markets of Alexandria, and the booming thunder of the monsoons that blew trading fleets to the shores of India.
