This introductory chapter, encyclopaedic in nature, covers the main aspects of catastrophe (CAT) risk from a qualitative perspective, offering an overview of what will be explored in quantitative terms in the subsequent chapters. It starts with the definition of the fundamental terms and concepts, such as peril, hazard, risk, uncertainty, probability, and CAT model. It then describes the historical development of catastrophe risk science, which was often influenced by the societal impact of some infamous catastrophes. The main periods are as follows: from ancient myths to medieval texts, mathematization (eighteenth and nineteenth centuries) and computerization (twentieth century). Finally, it provides an exhaustive list of perils categorized by their physical origin, including geophysical, hydrological, meteorological, climatological, biological, extraterrestrial, technological, and socio-economic perils. In total, 42 perils are covered, with historical examples and consequences for people and structures discussed for each one of them.

Like the panoramas, sets of lithographs based on officers’ drawings created new versions of the Arctic imaginary. Such products were too expensive to appeal to the average consumer, but printsellers’ practice of displaying lithographs in their windows and holding exhibitions ensured that this particular version of the Arctic reached far more people than simply those who could afford to purchase them. This chapter observes how the Arctic and the search were represented in three folios of lithographs produced from officers’ sketches (Browne, 1850; Cresswell, 1854; May, 1855). With attention to text and picture, using sketches and written sources, I offer close readings of these materials. This chapter emphasises how the lithographs, from 1850 to 1855, increasingly imply that a battle is being waged against the capricious Arctic nature in an effort to find Franklin. Significantly, the ability of these apparently factual lithographs to continually evolve and multiply, both digitally and on paper, ensures that they continue to inform ways of thinking about the nineteenth-century Arctic, and perhaps the present-day Arctic, into the future.
