Aeson or Aison (Greek, Ancient (to 1453);: Αἴσων) was a Greek town in ancient Thrace. It belonged to the Delian League as it appears in Athenian tribute registers between 454/3 and 429/8 BCE.[1] These registers are the only evidence for Aeson's location in Thrace.[1] It is possible that the Aeson River (which is identified with the modern Pelikas) of Macedonia mentioned by Plutarch is related.[2] It has also been suggested that Aeson could be identified with Aesa.[1]
Its site has not been located.[1]
