“It was one of those hours and scenes in which memory asserts an almost magical power, and, like the evening sun beaming on these mouldering towers, sends back her retrospective rays to light up the glories of the past.”
Irving describes historical memory as transforming ruins into a vivid imaginative encounter with lives and cultures that are no longer physically present.
