This paper explores the deep historical contexts for imagining natural disasters. By focusing on a foundational event in the Western disaster imaginary – the eruption of Vesuvius in AD 79 – and its remediation across centuries, the paper suggests that the real-time aesthetic of the mediation of extreme nature events that now abounds in contemporary culture is profoundly embedded in processes of historical intermediality. The term remediation is used to denote a genuinely historical mechanism by which past and present (process and event) are simultaneously made visible. Empirically, the paper investigates the superimposition of temporal dimensions in recreations of the ancient disaster from the late 18th century to the present. Using the insights gained from this spectacular case study, the paper ends by arguing that a re-temporalization of historical analysis itself is needed for history to contribute to contemporary concerns with the present as a conjuncture of multiple and conflicting time scales.
