Rhium or Rhion (Ancient Greek: Ῥίον) was a town of ancient Messenia, in the Thuriate Gulf, and also the name of one of the five divisions into which the mythical Cresphontes is said to have divided Messenia.[1] Strabo describes Rhium as over against Taenarum (ἀπεναντίον Ταινάρον), which is not a very accurate expression, as hardly any place on the western coast, except the vicinity of Cape Acritas, is in sight from Taenarum.[2]
Its site is unlocated.[3]
