How to Avoid Stinks, 1706
H. W. Bunbury, “The Battle of the Cataplasm,” 1773
When you are where Stinks are, open your Mouth, and breath through, and you shall not smell it, nor receive prejudice by it.
Thomas Lupton, A Thousand Notable Things
From the century that brought you the French and American Revolutions: a lesser-known revolution in Stinks management.
A related though more recent bit of folklore from my grandmother:
If something smells bad, imagine a rose and you won't smell it." Though by "it" she is referring to the imagined rose, and not the original odor.
