Sir Mortimer Wheeler 1945, and Jean-Marie Casal conducted archaeological excavations there in 1947–1950. The site was identified as the port of Podouke, known as an "emporium" in the Periplus of the Erythraean Sea and Ptolemy. Digs have found Amphorae, Arretine ware, Roman lamps, glassware, glass and stone beads, and gems at the site. Based on these excavations, Wheeler concluded that the Arikamedu was a Greek (Yavana) trading post that traded with Rome, starting during the reign of Augustus Caesar, and lasted about two hundred years—from the late first century BCE to the first and second centuries CE. Subsequent investigation by Vimala Begley from 1989 to 1992 modified this assessment, and now place the period of settlement from the 2nd century BCE to the 8th century CE.
