What We Know
- Name is **at least 2,500 years old** (Herodotus).
- **Greek Erythra Thalassa is the ultimate source** for all modern European names.
- **No single namer**—it emerged from the shared maritime vocabulary of Red Sea sailors, traders (Egyptians, Phoenicians, Greeks, Romans, Aksumites, Arabs, Indians).
- The sea itself—narrow, deep, hot, saline, reef-fringed, bloom-prone—**earned its name repeatedly** in every language of those who sailed it.
