Bisaltia (Greek: Βισαλτία) or Bisaltica was an ancient country which was bordered by Sintice on the north, Crestonia on the west, Mygdonia on the south and was separated by Odomantis on the north-east and Edonis on the south-east by river Strymon.The eponymous inhabitants, known as the Bisaltae, were a Thracian people. Later, the region was annexed by the kingdom of Macedon and became one of its districts. The most important town in Bisaltia was the Greek city of Argilos.[1] There was also a river named Bisaltes in the region, which has not been certainly identified.
In Roman times, Bisaltia crossed a branch of the via Egnatia, in which the Roman sources (Itineraria) mention four horses change stations : Trinlo (=Tragilos), Graero, Arason (=Arolos) and Euporia.[2] In various sites of Bisaltia have been found so far several interesting inscriptions of imperial times.[3]
Important towns of Bisaltia were Argilos, Berge and Brea.
