Final answer:
In 'Medea', Jason calling Medea a 'barbarian' reflects the Greeks' cultural prejudice against non-Greeks, seen as less civilized.
Step-by-step explanation:
In Euripides' play Medea, Jason refers to Medea as a 'barbarian', illuminating the cultural prejudices held by the Greeks against those they deemed as foreigners or culturally inferior. The term 'barbarian' comes from the Greek barbaros, which means 'foreigner', and was often used pejoratively to describe a culture perceived as less civilized. This view is portrayed in Jason's betrayal and Medea's subsequent actions, which were driven by the unjust and inhumane conventions of the time, resulting in her monstrous act of killing her own children.
