“You are like a lyre bereft of its reed.”
ὑφῃρέθη σου κάλαμος ὡσπερεὶ λύρας
(I suspect that the κάλαμος may refer to a reed pipe accompaniment rather than a part of the lyre, but I am not certain. In either case, the line seems to evoke the state of one of the women in the play who may have been the women captured after the fall of Troy.)
