In his magnum opus _Geographia_, the 2nd c. CE Roman writer Claudius Ptolemy presents a list of ports and emporia on the coasts of Gujarat, the Konkan and Southern India. Some like Sopara and Bharuch are well-described and corroborated by references in Indian literature and epigraphy; several remain identified. Ptolemy identifies a port or emporium named Dounga, between Sopara and Chaul—the modern villages of Dunge and Dungi answer to the brief in name and location. In this talk, Raamesh uses physical exploration and satellite imagery of both Dungi and Dunge to try and identify the Ptolemaic port. The talk will also touch upon exploratory methods for finding other archaeological sites associated with the Indo-Roman trade of antiquity.
