sylph

thumb|11. Air-people, wind-men, sylphs A sylph (also called sylphid) is an air spirit stemming from the 16th-century works of Paracelsus, who describes sylphs as (invisible) beings of the air, his elementals of air. A significant number of subsequent literary and occult works have been inspired by Paracelsus's concept: Robert Alfred Vaughan noted that "the wild but poetical fantasies" of Paracelsus had probably exercised a larger influence over his age and the subsequent one than is generally supposed, particularly on the Rosicrucians, but that through the 18th century they had become reduced to "machinery for the playwright" and "opera figurantes with wings of gauze and spangles".

==Etymology== "Sylph" is possibly a blend of from Latin sylvestris and nympha, sylvestris being a common synonym for sylph in Paracelsus. Anthony Trollope note a similar usage in the Aeneid, where silvestris is taken as an elliptical form of nympha silvestris ("forest nymph"). Jacob Grimm uses this phrase as a gloss for the Anglo-Saxon wudu-mær (roughly equivalent to "woodmare"), which he also takes as a metaphorical name for an echo. Jan Baptist van Helmont, a near contemporary of Paracelsus and coiner of the word "gas", uses sylvestris in the sense of "wild" to describe gaseous emissions, which may be connected to the Paracelsian usage. Thorpe's Northern Mythology connects the adjective sylvestres and the related silvaticas to European wild man legends. A related idea is that "sylph" is from a hyper-urbane respelling of a Latin neologism silves, but in either case this connection to the Latin root silva ("forest") is supported by Paracelsus' use of sylphes as a synonym for schrötlein, a German word for a tree spirit or especially an earth spirit in his Liber de Sanguine ultra Mortem.
