"Writing in 1927, the art historian Christopher Hussey attributed seven characteristics to the sublime, based on his reading of Burke : Obscurity, both physical and intellectual; Power; Privations, such as darkness, solitude, and silence; Vastness, either vertical or horizontal, both of which diminish the relative scale of the human observer; Infinity, which could either be literally or induced by two final characteristics of the sublime : Succession and Uniformity, both of which suggest limitless progression." - John Beardsley in Earthworks and Beyond pp 62
