Very interesting indeed🙂
Still I am asking myself whether this could not be a strange coincidence, like in Europe, where there is a historic region named „Galicia“ in Northwestern Spain and another one with the same name, which is situated in present-day Southeastern Poland and Western Ukraine 🙂
Yes, usually a coincidence. There was an Eryrthraea in Greece, but the Greeks also referred to the Indian Ocean (along with its ‘fingers’ like the Red Sea, Gulf of Suez, etc) as the Erythraean Sea.
