In Xenophon, βάρβαρος reverts to a military-operational category — but differently from Herodotus. Tyranny disappears entirely from the barbarian’s semantic field, γένος becomes its strongest association, and the Cyropaedia’s admired Persian king dismantles the barbarian/tyranny equivalence that tragedy and Plato constructed.
In Plato, βάρβαρος and Ἕλλην have become each other’s nearest neighbors — the dyad consolidated into a standing formula. But the philosophical vocabulary of soul, virtue, and reason is kept separate from the ethnic label, running in a parallel register that barely intersects with it.
A fastText model trained on Herodotus reveals that βάρβαρος is primarily a military term, not a philosophical one — and that the conceptual elaboration of group difference happens at the level of specific peoples, not the generic label.
A fastText model trained on Euripides shows that βάρβαρος has moved: from a military category in Herodotus to a political-social one in tragedy. The exception — φύσις barely changes — is the analytically important finding.
CADE century-sliced models covering six hundred years of ancient Greek writing show that φύσις never rises as an association of βάρβαρος at any point from the archaic period through the Hellenistic. What does shift is the geographic reference of the term, the strength of the Greek/Barbarian dyad, and the philosophical content of φύσις itself.
Hall argues that Greek tragedy invented the Barbarian as a coherent ideological construct serving Athenian democratic self-definition. Saïd argues that Euripides spent his career dismantling that same construct. Both are reading the same corpus. The disagreement is productive.
