Sylph

The light Coquettes in Sylphs aloft repair,
And sport and flutter in the Fields of Air.

- A. Pope, The Rape of the Lock, Canto 1

The sylph is an invisible elemental creature of air in Western thought, originating from Paracelsus, a 16th Century alchemist and occultist. In his famous satirical poem The Rape of the Lock, Alexander Pope mocked the alchemical tradition by presenting the sylph as being chemically condensed humors of peevish women. Women who are full of vanity become sylphs when they die.
