Until Newton the Senecans had dominated the literary scene from Montaigne to Pascal and from Donne to Pope. Their preoccupation was with the literary techniques for arresting and projecting some phase of the human mind: to arrest in order to project, and to project in order to contemplate. Like the inventors of cinema at the beginning of this century they hit upon the technique of stylistic discontinuity as a means of arresting a moment of consciousness. The movie camera takes a thousand still shots in order to capture the aspects of a brief moment. The style coupé and the “cutting period” attempted something comparable in the essay and the poem. But to have carried this art further than Pope was probably impossible. At any rate the advent of Newton’s Optics diverted artistic effort from poetic statement to the use of external landscape as a means of projecting and controlling states of mind under the guidance of two major concepts. The first of these derived from the study of the visual harmonics of the spectrum which led to a revival of the classic images of the harps of Aeolus and Memnon. If the surfaces of matter were varied prisms for revealing the qualities of light, then the entire visible and audible world could be conceived as a species of visual music. The second concept is related to the first. For, if the external world is attuned to the mind of man then the whole of Nature is a language and the poet is a pontifex or bridge between the two worlds.
