The nurse provides the audience with information about what has happened to Medea. She tells us of Jason's betrayal of his wife and gives us information about Medea's present condition:
"She calls out to the gods to witness
how Jason is repaying her favours.
She just lies there. She won't eat—her body
she surrenders to the pain, wasting away,
always in tears, ever since she found out
how her husband has dishonoured her". (Lines 26-35)
