Sophocles did not write such grand lines, yearning for the truth, as Æschylus, but his plays, of Ajax’ madness, and especially of Antigone’s self-devotion, were more touching, and full of human feeling; and Euripides, who was a little younger, wrote plays more like those of later times, with more of story in them, and more characters, especially of women.  He even wrote one in which he represented Helen as never having been unfaithful at all; Venus only made up a cloud-image to be run away with by Paris, and Helen was carried away and hidden in Egypt, where Menelaus found her, and took her home.  The works of these three great men have always been models.  The Greeks knew their plays by heart almost as perfectly as the _Iliad_ and _Odyssey_, and used to quote lines wherever they applied.
