In A.D. 75 a sea-faring, Greek-speaking Egyptian merchant wrote a book called Periplus, which talks about various ports in India. One of the ports he mentioned is Musiris, which is near present day Kodungallur in Kerala. Dr. Shajan, an archaeologist thinks that ancient Musiris is a town called Pattanam, located 12 KM away from Kodungallur.
Pattanam, on the other hand, has yielded amphora (holding vessels) of Roman make and those made elsewhere in the Persian Gulf. This shows that Pattanam had trade not only with Rome but also with places in the Persian Gulf, she added. [Tracing an ancient trading route]
Is this enough evidence to identify Pattanam as Musiris? While there has been evidence of trade between Kerala and ancient Rome, more research is needed according to visiting fellow of Southampton University, Roberta Tambor.
