Seneca
On the Nature of Things
Seneca / From open access
In what way does the wind arise? The same as in our bodies winds are formed from food, which, when emitted, extremely offend the nostrils and sometimes are released from the stomach with a loud noise, or silently at other times, so, according to the opinion of some, the great nature of things itself emits winds by digesting its food. We are fortunate that it never suffers indigestion; otherwise something horribly foul and filthy would threaten us.
Seneca, On the Nature of Things, first century CE
