What a line. It is from the greek tragedy "Agamemnon", first part of the trilogy The Oresteia by Aeschylus.
The great thing about classic literature is that it scratches an itch you never knew you had. It puts words to ghostly thoughts in your mind that appear only for a second and then disappear again because they have not yet a full form. Classics give flesh to those thoughts because when you read a line like the one above, you say, "Somehow that is true." Grace does come somehow violent. Such is the weird way of reality; through the violent and the painful, goodness comes; out of the darkness, light shines.
The Oresteia is a rite of passage from savagery to civilization. - Robert Fagles
