Contemplating John Marston

"It is possible that what distinguishes poetic drama from prosaic drama is a kind of doubleness in the action, as if it took place on two planes at once. . . .In poetic drama a certain apparent irrelevance may be the symptom of this doubleness; or the drama has an under-pattern, less manifest than the theatrical one. We sometimes feel, in following the words and behaviour of some of the characters of Dostoevsky, that they are living at once on the plane that we know and on some other plane of reality from which we are shut out: their behaviour does not seem crazy, but rather in conformity with the laws of some world that we cannot perceive. More fitfully, and with less power, this doubleness appears here and there in the work of Chapman, especially in the two Bussy D’Ambois plays. . . . It is not by writing quotable "poetic" passages, but by giving us the sense of something behind, more real than any of his personages and their action, that Marston established himself among the writers of genius."  ('Selected Essays')
