ABDERA, an ancient seaport on the south coast of Spain, between Malaga and New Carthage, in the district inhabited by the Bastuli. Founded by the Carthaginians, it became an impor tant town in the Roman province of Hispania Baetica. It was on a hill above the modern Adra (q.v.). Its most ancient coins bear the Phoenician inscription, abdrt, with the head of Heracles (Mel karth) and a tunny-fish; those of Tiberius (who seems to have made the place a colony) show the chief temple of the town with two tunny-fish erect in the form of columns. For inscriptions relating to the Roman municipality see Corpus Inscriptionum Latinarum, ii. 267.
