1816 is known as “the year without a summer” — the eruption of Indonesia’s Mount Tambora flung huge amounts of volcanic dust into the atmosphere, dropping temperatures worldwide and giving the sky a sallow cast that’s visible in Turner’s landscapes of the period (above).

It was a great calamity for farmers, but a boon for horror literature — the “wet, ungenial summer” forced Mary Shelley and John Polidori indoors on their Swiss holiday, where they wrote both Frankenstein and The Vampyre.
