Origin & History
The concept of emotions or rumors existing “in the air” dates back centuries in English literature. In Early Modern English and classical prose, the atmosphere (the surrounding air) was frequently treated as the medium through which invisible influences, spirits, diseases (miasma theory), or universal sentiments passed among people.
By the 18th and 19th centuries, writers routinely described intangible public moods, such as revolution, romance, or foreboding, as being literal components of the surrounding air.
