The Periplus of the Erythraean Sea, a Greek-language sailing guide likely written by a merchant familiar with Red Sea and Indian Ocean routes, describes ports, goods, and sailing conditions from Egypt down the East African coast and across to India. It reflects a mature understanding of the seasonal monsoon winds that allowed ships to sail directly across the Arabian Sea rather than hugging the coastline, shortening voyages considerably. The text lists goods such as pepper, textiles, ivory, and precious stones moving between Roman Egypt, Arabia, East Africa, and Indian ports. This monsoon-based maritime trade connected the Roman Mediterranean economy with South Asia on a regular, if seasonal, basis.
Relevance to Trade History
The Periplus documents one of the earliest well-recorded long-distance maritime trade systems, showing how monsoon navigation linked the Mediterranean world directly to South Asia.
