The story of the word

For Sophocles the miasma is ritual pollution rather than smell: Thebes suffers plague because an unpunished killing has stained the city, and the plot is a search for the stain. Nineteenth-century sanitarians took the word literally and blamed cholera on bad air, until John Snow traced an outbreak to one water pump in Broad Street. The moral sense came first by two thousand years.
