Random Fact #6,741
Mary Shelley's iconic novel, Frankenstein, may never have been written if Mount Tambora, a volcano in what is now Indonesia, hadn't erupted in 1815.
Let me set the dominoes:
Mount Tambora erupts on April 10, 1815.
The eruption is so large (the largest volcanic eruption in at least 1,300 years) that the ensuing ash and gasses released into the atmosphere led to a volcanic winter.
Average global temperatures decrease by 0.4–0.7 °C.
In 1816, summer temperatures in Europe are the coldest of any on record between 1766 and 2000. (Because of this, the year becomes known as "The Year Without a Summer").
Because of the drastic drop in temperature, people stay inside a lot more.
Staying inside because it's cold but without much to do, Mary Shelley, Percy Shelley, John Polidori, and Lord Byron have a competition to see who can write the best horror story.
For the contest, Mary writes the first iteration of Frankenstein.
In 1818, "Frankenstein; or, The Modern Prometheus" is published.
In 2025, Guillermo del Toro directs a film adaptation of Shelley's work.
