Meaning

Pachnē is frost. Its relation to dew provides a comparison for other forms of atmospheric water.

Use in the book

Arrian says that freezing produces frost and compares frost’s relation to dew with snow’s relation to rain. The analogy distinguishes freezing from the gathering of moisture without freezing. Plato’s quoted classification similarly connects frost with dew congealing on earth, while arranging the other products by location and degree.
