Roman Empire [SEP] Trade and commodities
Roman provinces traded among themselves, but trade extended outside the frontiers to regions as far away as China and India. The main commodity was grain. Chinese trade was mostly conducted overland through middle men along the Silk Road; Indian trade, however, also occurred by sea from Egyptian ports on the Red Sea. Along these trade paths, the horse, upon which Roman expansion and commerce depended, was one of the main channels through which disease spread. Also in transit for trade were olive oil, various foodstuffs, "garum" (fish sauce), slaves, ore and manufactured metal objects, fibres and textiles, timber, pottery, glassware, marble, papyrus, spices and "materia medica", ivory, pearls, and gemstones.
