'''Undines''' ({{IPAc-en|ˈ|ʌ|n|d|iː|n|z|,_|ə|n|ˈ|d|iː|n|z|}}; also '''ondines''') are a category of [elemental](/source/elemental) beings associated with water, stemming from the [alchemical](/source/alchemy) writings of [Paracelsus](/source/Paracelsus). Later writers developed the undine into a water [nymph](/source/nymph) in its own right, and it continues to live in modern literature and art through such adaptations as Danish [Hans Christian Andersen](/source/Hans_Christian_Andersen)'s 1837 "[The Little Mermaid](/source/The_Little_Mermaid)" and the 1811 novella ''[Undine](/source/Undine_(novella))'' by [Friedrich de la Motte Fouqué](/source/Friedrich_de_la_Motte_Fouqu%C3%A9).

==Etymology==
The term ''Undine'' first appears in the [alchemical](/source/alchemy) writings of [Paracelsus](/source/Paracelsus),{{sfnp|Silver|2000|p=38|ps=none}} a Renaissance [alchemist](/source/alchemy) and physician. It derives from the [Latin](/source/Latin) word ''unda'', meaning "wave", with a diminutive "-ina" which in modern Italian could translate the term "little wave" (or alternatively from Lithuanian language word Vandene (water=vanduo) <ref>{{cite web |last=Strong |first=George Templeton |title=''Ondine'', Suites Nos. 1–3 |url=http://www.naxosdirect.com/STRONG-Ondine---From-a-Notebook-of-Sketches-Suites-1-3/title/8559078/ |access-date=2008-05-16 |archive-date=2014-03-07 |archive-url=https://web.archive.org/web/20140307035302/http://www.naxosdirect.com/Strong-Ondine---From-A-Notebook-of-Sketches-Suites-1-3/title/8559078/ |url-status=dead }}</ref>), and first appears in Paracelsus' ''[A Book on Nymphs, Sylphs, Pygmies, and Salamanders, and on the Other Spirits](/source/A_Book_on_Nymphs%2C_Sylphs%2C_Pygmies%2C_and_Salamanders%2C_and_on_the_Other_Spirits)'', published posthumously in 1566.{{r|OED}} ''Ondine'' is an alternative spelling,{{sfnp|Meletinskiĭ|1998|p=472|ps=none}} and has become a female given name.{{sfnp|Rifkin|2011|p=258|ps=none}}

== Elementals ==
Paracelsus believed that each of the four [classical element](/source/classical_element)s{{--}}[earth](/source/earth_(classical_element)), [water](/source/water_(classical_element)), [air](/source/air_(classical_element)) and [fire](/source/fire_(classical_element)){{--}}is inhabited by different categories of [elemental spirits](/source/elemental), liminal creatures that share our world: [gnome](/source/gnome)s, undines, [sylph](/source/sylph)s and [salamanders](/source/salamander_(legendary_creature)) respectively.{{sfnp|Alban|2003|pp=47–48|ps=none}} According to Paracelsus (as paraphrased by occultist [Manly P. Hall](/source/Manly_P._Hall)), the spiritual inhabitants of the elements are "invisible, spiritual counterparts of visible Nature{{nbsp}}... many resembling human beings in shape, and inhabiting worlds of their own, unknown to man because his undeveloped senses were incapable of functioning beyond the limitations of the grosser elements".{{sfnp|Hall|1928|p=105}}{{Refn|Cf. also Hartmann (1902)<ref name="hartmann-on-paracelsus1902"/> on Paracelsus.}}

==Description and common attributes==
[[File:Les Ondines - Antoine Calbet.jpg|thumb|''Les Ondines'' by Antoine Calbet, [Musée des Beaux-Arts de Cambrai](/source/Mus%C3%A9e_des_Beaux-Arts_de_Cambrai)]]

Undines are almost invariably depicted as being female, which is consistent with the ancient Greek idea that water is a female element.{{sfnp|Hall|1928|p=107}} They are usually found in forest pools and waterfalls,{{sfnp|Bane|2013|p=333|ps=none}} and their beautiful singing voices{{sfnp|Woodworth|Pope Morris|1827|p=2|ps=none}} are sometimes heard over the sound of water. The group contains many species, including [nereid](/source/nereid)es, [limnad](/source/limnad)s, [naiad](/source/naiad)es, [mermaid](/source/mermaid)s and [potamides](/source/potamides_(mythology)).{{sfnp|Hall|1928|p=107}}

What undines lack, compared to humans, is an [immortal soul](/source/immortal_soul).{{sfnp|Hartmann|1902|pp=151–152}} Marriage with a human shortens their lives on Earth, but earns them an immortal human soul,{{r|Fass}} a view which was professed by Paracelsus.{{sfnp|Hartmann|1902|pp=155–156}}

The offspring of a union between an undine and a man are humans with a soul, but also with some kind of aquatic characteristic, called a watermark. Moses Binswanger, the protagonist in [Hansjörg Schneider](/source/Hansj%C3%B6rg_Schneider)'s ''Das Wasserzeichen'' (1997), has a cleft in his throat, for instance, which must be periodically submerged in water to prevent it from becoming painful.{{r|Schneider}}

==Paracelsus==
The [ancient Greek](/source/Ancient_Greece) philosopher [Empedocles](/source/Empedocles) ({{circa|490}} – {{circa|430 BC}}) was the first to propose that the four classical elements were sufficient to explain everything present in the world.{{sfnp|Macauley|2010|p=72|ps=none}}

Paracelsus's view of elemental spirits may have grown out of the folklore that a very human-like race of spirits exists in a different "plane" from humans, according to Celticist [Henry Jenner](/source/Henry_Jenner).<ref>{{harvp|Silver|2000|p=40|ps=none}}:
{{blockquote|The subdivisions and elaborations [of nature spirits]{{nbsp}}... by Paracelsus, the Rosicrucians, and the modern theosophists are no doubt amplifications of that popular belief in the existence of a race, neither divine nor human, but very like to human beings, who existed on a "plane" different from that of humans, though occupying the same space which{{nbsp}}... resembles the theory of these mystics in its main outlines, and was probably what suggested it to them.}}</ref>

According to Paracelsus in ''Liber de Nymphis'', there are four types of spirit-men, which each reside in one of the four elements: earth, air/wind, fire, and water. These spirits are similar to human beings, but not endowed with [immortal soul](/source/immortal_soul)s.{{sfnp|Hartmann|1902|pp=151–152}}<ref name="roeder2013"/> But Undines ("water women", "water people"{{sfnp|Paracelsus|Sigerist tr.|1941|p=238}}) in particular are able to consort with humans more than the spirits of other elements, and are most capable of entering into marriage with a human male, thus earning a kernel of the immortality. The children born to her will be imparted with human souls as well. For this reason, the Undines (also called Nymphs) yearn to marry a human husband.{{sfnp|Paracelsus|Sigerist tr.|1941|p=238}}{{sfnp|Hartmann|1902|pp=155–156}}<ref name="roeder2013"/> If a man has an Undine/Nymph for a wife, he must be careful not to offend her in the presence of water, or she will return to her element.<ref>{{harvp|Paracelsus|Sigerist tr.|1941|p=242}}:"When they have been provoked in any way by their husbands while they are on water, they simply drop into the water, and nobody can find them any more. To the husband it is as if she were drowned.. And yet.. he many not consider her dead."</ref>{{sfnp|Hartmann|1902|pp=156–157}}<ref name="roeder2013"/>

This motif of the husband's calumny causing Undine's departure also occurs in Fouquet's novella (and Hoffmann's opera<ref name="chantler2017"/>). Undine's husband Huldbrand had been forewarned not to do so,<ref>{{harvp|Alban|2003|p=55}}, quoting La Motte pp. 73–74.</ref> but he rekindles his unfaithful relationship with Bertalda, he commits the insult, and she splashes away beneath the Danube.<ref name="roeder2013"/>

Paracelsus also emphasizes that even if the sylph/undine has returned to water, the marriage still remains valid, and she cannot be presumed to be dead,{{sfnp|Paracelsus|Sigerist tr.|1941|p=242}} another theme exploited by Fouquet's novella: thus, as her husband's transgression necessitates her departure into the watery world, she makes the insistence on her husband that his vow of fidelity still remains in place, and breaking it would have deadly consequence.<ref name="markx2015"/><ref>{{harvp|Alban|2003|p=56}}: "her union with him extends to her own watery element".</ref> And she continues to remind to her husband to remain faithful, in the form of a message in a dream between the swan song.{{sfnp|Alban|2003|p=56}}

According to Paracelsus, the Undine will still receive her place on the [Day of Judgment](/source/Day_of_Judgment),{{sfnp|Paracelsus|Sigerist tr.|1941|p=242}} i.e., she will still preserve the immortal soul she earned through marriage.

David Gallagher argues that, although they had Paracelsus as a source, 19th and 20th-century German authors found inspiration for their many versions of undine in classical literature, particularly [Ovid](/source/Ovid)'s ''[Metamorphoses](/source/Metamorphoses)'', especially given the transformation of many of their undines into springs: Hyrie (book VII) and [Egeria](/source/Egeria_(mythology)) (book XV) are two such characters.{{sfnp|Gallagher|2009|p=345|ps=none}}

Later writers embellished Paracelsus' undine classification by developing it into a water nymph in its own right. The romance ''[Undine](/source/Undine_(novella))'' by [Friedrich de la Motte Fouqué](/source/Friedrich_de_la_Motte_Fouqu%C3%A9), published in 1811, is based on a passage in Paracelsus' ''Book on Nymphs'' in which he relates how an undine can acquire an immortal soul by marrying a human,{{sfnp|Sax|1998|p=129|ps=none}} although it likely also borrows from the 17th-century Rosicrucian novel ''[Comte de Gabalis](/source/Comte_de_Gabalis)''.{{r|Seeber}}

''Ondine'' was the title of one of the poems in [Aloysius Bertrand](/source/Aloysius_Bertrand)'s collection ''[Gaspard de la Nuit](/source/Gaspard_de_la_Nuit_(book))'' of 1842.

[Debussy](/source/Claude_Debussy), [Sibelius](/source/Jean_Sibelius), [Fauré](/source/Gabriel_Faur%C3%A9), and [Schoenberg](/source/Arnold_Schoenberg) all wrote music adaptions of the play.{{sfnp|Begam|Smith|2016|p=88|ps=none}}{{sfnp|Gallagher|2009|p=357|ps=none}}{{sfnp|Jacobs|2006|p=53|ps=none}} The 1939 play ''[Ondine](/source/Ondine_(play))'' by French dramatist [Jean Giraudoux](/source/Jean_Giraudoux) is also based upon Fouqué's novella,{{sfnp|Gallagher|2009|p=352|ps=none}} as is ''[Ondine](/source/Ondine_(ballet))'', a ballet by composer [Hans Werner Henze](/source/Hans_Werner_Henze) and choreographer [Frederick Ashton](/source/Frederick_Ashton){{r|Lillyman}} with [Margot Fonteyn](/source/Margot_Fonteyn) as Undine.{{r|Holschuh}} Austrian author [Ingeborg Bachmann](/source/Ingeborg_Bachmann), a friend of Henze's who collaborated with him frequently, attended the premiere of the ballet in London, and published her short story "Undine geht" in the collection ''Das dreißigste Jahr'' (1961),{{r|Baackmann}} in which Undine "is neither a human nor a water spirit, but an idea".{{r|Holschuh}}

Fouqué's ''Undine'' also exerted an influence on [Hans Christian Andersen](/source/Hans_Christian_Andersen)'s "[The Little Mermaid](/source/The_Little_Mermaid)" (1837),{{sfnp|Høyrup|2008|p=372|ps=none}}{{r|Holbek}} and [H.D.](/source/H.D.) plays on this identification in her autobiographical novel ''[HERmione](/source/HERmione)'' (1927).{{sfnp|H.D.|1981|p=120|ps=none}}{{sfnp|Friedman|2008|p=114|ps=none}} Burton Pollin notes the popularity of the tale in the English-speaking world: translations in English appeared in 1818 and 1830, and a "superior version" was published by American churchman Thomas Tracy in 1839 and reprinted in 1824, 1840, 1844, and 1845; he estimates that by 1966 almost a hundred English versions had been printed, including adaptations for children. [Edgar Allan Poe](/source/Edgar_Allan_Poe) was profoundly influenced by Fouqué's tale, according to Pollin, which may have come about through Poe's broad reading of [Walter Scott](/source/Walter_Scott) and [Samuel Taylor Coleridge](/source/Samuel_Taylor_Coleridge):{{r|Pollin}} Scott had derived the character of the White Lady of Avenel (''[The Monastery](/source/The_Monastery%3A_A_Romance)'', 1820) from ''Undine'',{{r|Boatright}} and a passage by Coleridge on ''Undine'' was reprinted in Tracy's 1839 edition.{{r|Pollin}}

== Ondine's curse ==
{{main|Central hypoventilation syndrome}}

Congenital central hypoventilation syndrome, a rare medical condition in which those affected lack [autonomic](/source/autonomic_nervous_system) control of their breathing and are hence at risk of suffocation while sleeping, is also known as Ondine's curse.{{sfnp|Robinson|2010|p=28|ps=none}} Ondine, the eponymous heroine of Giraudoux's play, tells her future husband Hans, whom she has just met, that "I shall be the shoes of your feet{{nbsp}}... I shall be the breath of your lungs".{{sfnp|Weiss|1964|p=334|ps=none}} Ondine makes a pact with her uncle, the King of the Ondines, that if Hans ever deceives her he will die. After their honeymoon Hans is reunited with his first love, the Princess Bertha, and Ondine leaves him, only to be captured by a fisherman six months later. On meeting Ondine again on the day of his wedding to Bertha, Hans tells her that "all the things my body once did by itself, it does now only by special order{{nbsp}}... A single moment of inattention and I forget to breathe".{{sfnp|Weiss|1964|p=364|ps=none}} Hans and Ondine kiss, and he dies.

Critics have pointed out that medical texts on the syndrome frequently misinterpret Ondine as a vengeful or malevolent character; in the play, Ondine is not responsible for the curse and tries to save Hans.<ref>{{Cite journal |last=Sugar |first=Oscar |date=1978 |title=In Search of Ondine's Curse |journal=JAMA |volume=1978;240 |issue=3 |pages=236–237 |doi=10.1001/jama.1978.03290030054019|pmid=351225 }}</ref>
