I hate to tell Archeology Magazine that the Persian Gulf is a long ways from the Indus Valley.

Good point. Do some people refer to the “Persian Gulf” as including the Gulf of Oman like they’re one thing?

By the time of Herodotus at the latest, the Greeks referred to the Indian Ocean and all these other gulfs, bays, and seas as the Erythraean Sea, and knew that Africa had been circumnavigated by the Phoenicians.

No doubt they mean Arabian *Sea*, of which Gulf of Oman is a part. Modern ‘scholars’ probably just don’t know that Arabian Gulf is sometimes just an alternate name for Persian Gulf.
