In Ion, disturbing riptides of thought and feeling run just below the often shimmering surfaces of Euripidean melodrama. Although the play contains some of Euripides' most beautiful lyrical writing, it quivers throughout with near disasters, poorly informed actions and misdirected intentions that almost result in catastrophe. Kreousa says at one point that good and evil do not mix, but Euripides' argument, and what the youthful Ion strives to understand, is that human beings are not only compounded of good and evil, but that the two are often the same thing differently experienced, differently understood, just as beauty and violence are mixed both in the gods and in the mortal world.
