What is "parauaea"

Parauaea was an ancient Greek region in Epirus. The area was incorporated into Macedon in 350 BC as part of Upper Macedonia. The Thesprotian tribe inhabiting it was called Parauaioi . Parauaei under king Oroedus and 1000 Orestai, entrusted to Oreoedus by Antiochus, their king, had joined the Spartans under Cnemus during the 3rd year of the Peloponnesian war. Rhianus (3rd century BC) calls them a Thesprotian nation, and so does Stephanus of Byzantium quoting Rhianus. Their name, Parauaioi meant, those dwelling beside Aous, a river in Epirus.
