'''''The Swallow's Tail — Series on Catastrophes''''' ({{lang-fr|La queue d'aronde — Série des catastrophes}}) was [[Salvador Dalí]]'s last painting. It was completed in May 1983, as the final part of a series based on [[René Thom]]'s [[catastrophe theory]].


Thom suggested that in four-dimensional phenomena, there are seven possible equilibrium surfaces, and therefore seven possible discontinuities, or "elementary catastrophes": [[Catastrophe theory#Fold catastrophe|fold]], [[Catastrophe theory#Cusp catastrophe|cusp]], [[Catastrophe theory#Swallowtail catastrophe|swallowtail]], [[Catastrophe theory#Butterfly catastrophe|butterfly]], [[Catastrophe theory#Hyperbolic umbilic catastrophe|hyperbolic umbilic]], [[Catastrophe theory#Elliptic umbilic catastrophe|elliptic umbilic]], and [[Catastrophe theory#Parabolic umbilic catastrophe|parabolic umbilic]].<ref>Thom, René, ''Structural stability and morphogenesis. an outline of a general theory of models'', (D.H.Fowler, trans.) (Reading, Mass. London. Benjamin. 1975). Originally published in French as ''Stabilité structurelle et morphogénèse'', 1972.</ref>  "The shape of Dalí’s Swallow’s Tail is taken directly from Thom’s four-dimensional graph of the same title, combined with a second catastrophe graph, the s-curve that Thom dubbed, "the cusp".  Thom’s model is presented alongside the elegant curves of a [[cello]] and the instrument’s f-holes, which, especially as they lack the small pointed side-cuts of a traditional f-hole, equally connote the mathematical symbol for an integral in [[calculus]]: <math>\int_{}^{}</math> ."<ref>King, Elliott in Dawn Ades (ed.), ''Dalí'' (Milan: Bompiani Arte, 2004), 418-421.</ref>


In his 1979 speech, "Gala, Velázquez and the Golden Fleece", presented upon his 1979 induction into the prestigious Académie des Beaux-Arts of the Institut de France, [[Dalí]] described Thom’s theory of catastrophes as ‘the most beautiful aesthetic theory in the world’.<ref>Dalí, Salvador, ‘Gala, Velásquez and the Golden Fleece’ (9 May 1979). Reproduced in-part in Robert Descharnes, ''Dalí, the Work, the Man'' (New York: Harry N. Abrams, 1984) 420. Originally published in French as ''Dalí, l'oeuvre et l'homme'' (Lausanne: Edita, 1984).</ref>  He also recollected his first and only meeting with René Thom, at which Thom purportedly told Dalí that he was studying tectonic plates; this provoked Dalí to question Thom about the railway station at [[Perpignan]], France, which the artist had declared in the 1960s as the centre of the universe.  Thom reportedly replied, "I can assure you that Spain pivoted precisely — not in the area of — but exactly there where the Railway Station in [[Perpignan]] stands today".   Dalí was immediately enraptured by Thom’s statement, influencing his painting ''Topological Abduction of Europe — Homage to René Thom'', the lower left corner of which features an equation closely linked to the ‘swallow’s tail’: <math>V = x^5 + ax^3 + bx^2 + cx,</math> an illustration of the graph, and the term ‘queue d'aronde’.  The seismic fracture that transverses ''Topological Abduction of Europe'' reappears in ''The Swallow’s Tail'' at the precise point where the y-axis of the swallow’s tail graph intersects with the S-curve of the [[Cusp (singularity)|cusp]].<ref>King, E., 418-421.</ref>
