Marine archaeologists utilizing deep-sea autonomous underwater vehicles (AUVs) have located the wreck of a 1st-century Roman merchant vessel resting in the silt off the southern coast of Sri Lanka. The ship, identified as a 'Pearl-Merchant's Galleon', was found carrying a rare cargo of lead-sealed glass vials containing hundreds of calcified organic pearls and semi-precious gems from the region.
This discovery provides the first physical evidence of Roman trade missions venturing as far as the Indian Ocean to procure luxury commodities directly from source markets. The vessel's design, featuring a double-planked hull reinforced with lead sheathing, suggests it was specifically built for the long and treacherous journey between the Red Sea and the Bay of Bengal.
