Cool article. An excerpt that I liked:

the research showed that the maritime trade route between India and Egypt in antiquity appeared to be even more productive and lasted longer than scholars had thought.

Also, it was not an overwhelmingly Roman enterprise, as had been generally assumed. The researchers said artifacts at the site indicated that the ships might have been built in India and were probably crewed by Indians.

"We talk today about globalism as if it were the latest thing, but trade was going on in antiquity at a scale and scope that is truly impressive," Dr. Wendrich said.

Somehow I never thought of the ancient Indian peoples as seafarers. Thanks for the eye-opener, Insel.
