In the mid-first century CE, Greco-Roman mariners operating from Egypt mastered the seasonal monsoon winds of the Indian Ocean, enabling direct open-water voyages from the Red Sea ports of Berenike and Myos Hormos to the markets of India rather than the slow coast-hugging routes of earlier times.
The breakthrough was attributed by Pliny the Elder to the navigator Hippalus (c. 45-47 CE), after whom the southwest monsoon wind was named, and the resulting commerce was documented in unusual detail by the anonymous Greek merchant's manual known as the Periplus of the Erythraean Sea (composed c. 40-70 CE). Trade surged dramatically: the geographer Strabo reported that as many as 120 ships sailed annually from Myos Hormos to India under Augustus, where previously only a handful had made the journey. Roman gold and silver coin, wine, glass, and metalware flowed east in exchange for pepper, spices, gemstones, fine textiles, and silk routed through hubs such as Muziris and Barygaza, with Pliny famously lamenting that India, China, and Arabia together drained one hundred million sesterces from the empire each year. This monsoon-powered network bound the Mediterranean economy to South Asia on an unprecedented scale and is distinct from the later 166 CE Roman embassy recorded in Chinese sources.
