Create a five-slide Instagram carousel tracing the book’s account of Vesuvius in A.D. 79, from its earlier description as a wooded, cultivated mountain to the eruption and the burial of Herculaneum and Pompeii. Give each slide one step in that single historical episode; preserve the reported eight days and nights and the account of ash-laden torrents without implying that every detail is independently verified. Keep the final slide focused on the event’s consequence, not on introducing a new topic. Use only source-supported claims, with no modern correction unless separately backed by a vetted linked source. Include a concise native caption within the 200-visible-character limit; develop portrait-first visuals on a 1024×1536 canvas and keep essential action inside the central 4:5 safe area.
