Spazio e lingua nella 'costruzione' greca dell'identità etnica. Alcune osservazioni a partire da Erodoto

The paper aims to offer an account of some representative opinions of ancient Greeks about the role of the space, conceived in its geographical/environmental value, in which a certain population lives, as well as of the language spoken by a population, in order to build historically the concept of Greek nation (to Hellenikón). The different positions expressed on these matters by Herodotus, Thucydides, Strabon and Pausanias are discussed, and the examination mostly concernes the ethnic and historical-linguistic aspects of the representation of the Dorians and Ionians.
