Caravans make regular departures from Luoyang with Chinese ginger, cassia (a type of cinnamon), and silk to be bartered in Central Asia for gold, silver, glassware, pottery, cloth, and intaglio gems from Rome. Suetonius, Roman historian, publishes Viris Illustribus ("On Famous Men" – in the field of literature).
