The van Gogh masterpiece ‘The Starry Night’ is more art than science, researchers report

 

VCU’s Mohamed Gad-el-Hak says the swirls depicted in the painting do not follow the rules of flow physics after all.

RICHMOND, Va. (April 1, 2025) – The Dutch master Vincent van Gogh may have painted one of Western history’s most enduring works, but “The Starry Night” is not a masterpiece of flow physics – despite recent attention to its captivating swirls, according to researchers from Virginia Commonwealth University and the University of Washington.

The post-Impressionist artist painted the work (often referred to simply as “Starry Night”) in June 1889, and its depiction of a pre-sunrise sky and village was inspired in part by the view from van Gogh’s asylum room in southern France. The painting is part of the permanent collection of the Museum of Modern Art in New York City.

Last year, a paper published in the September issue of Physics of Fluids – “Hidden Turbulence in van Gogh’s ‘The Starry Night’” – received considerable notice by positing that the eddies, or swirls, painted by van Gogh adhere to Kolmogorov’s theory of turbulent flow, which explains how air and water swirls move in a somewhat chaotic pattern. “[van Gogh] was able to reproduce not only the size of whirls/eddies, but also their relative distance and intensity in his painting,” the paper read.

However, those conclusions are unfounded, according to Mohamed Gad-el-Hak, Ph.D., the Inez Caudill Eminent Professor in VCU’s Department of Mechanical and Nuclear Engineering, and James J. Riley, Ph.D., the inaugural Paccar Professor of Mechanical Engineering at the University of Washington. Their report –  “Is There Hidden Turbulence in Vincent van Gogh’s ‘The Starry Night’?” – appears in the latest issue of Journal of Turbulence.

“The Kolmogorov theory, which is named for the 20th-century Soviet mathematician Andrey Kolmogorov, is perhaps the most famous theory in turbulence research,” Gad-el-Hak said. “That theory applies to the velocity field in fluid flows.’’ The theory was extended independently by Alexander Obukhov, Ph.D., and Stanley Corrsin, Ph.D., to scalar fields in a turbulent flow, such as fluid density, temperature, pressure, and related quantities. As doctoral students at Johns Hopkins University, Gad-el-Hak and Riley studied under Corrsin, and were well-versed in the theory.

It was this extension of the theory to scalars in turbulent flows that was employed by the authors of the paper in Physics of Fluids, but Gad-el-Hak and Riley said that was erroneous. “Our foundational objection … is that there is no identifiable, measurable scalar fluid property in the painting that can be used to apply the theory of Obukhov and Corrsin,” Riley said. “Furthermore, the atmospheric flow field assumed does not even closely satisfy the assumptions required of the theory.” Gad-el-Hak and Riley therefore infer that the conclusions in the Physics of Fluids paper are unfortunately totally flawed, and “that the painting is fascinating and very abstract, and in fact this is an element of what makes it such an iconic work of art.”

Fratello Sole, Sorella Luna. Nature in Art, between Fra Beato Angelico, Leonardo and Corot,

 Perugia, Galleria Nazionale dell’Umbria

15 March – 15 June 2025

More than eighty works by the greatest Italian and European artists tell the story of the revolution launched by Saint Francis’s Canticle of the Sun, in the year that marks its eighth centennial.

Exceptional loans have been made by the Louvre, the Rijksmuseum, the Mauritshuis, the Vatican Museums and Italy’s leading public museums, constituting a journey through masterpieces from the thirteenth to the nineteenth centuries.

From 15 March to 15 June 2025, the National Gallery of Umbria in Perugia will be hosting the exhibition Fratello Sole, Sorella Luna. Nature in Art, between Fra Beato Angelico, Leonardo and Corot, on the occasion of the eighth centennial of the composition of the Canticle of the Sun by Saint Francis of Assisi. Not only one of the very first works of poetry in old Italian, it was also the first expression of a new relationship with Nature, to which the saint spoke for the first time in terms of intimacy, in an ecological ideal, in the etymological sense of the term, that was to exert an incredible influence on art from the thirteenth century onwards.

Curated by Costantino D’Orazio, Director of the National Museums of Perugia – Umbria Regional Directorate of National Museums, together with Veruska Picchiarelli and Carla Scagliosi, art historians responsible for the collections at the National Gallery of Umbria, and held under the patronage of the Region of Umbria and of the Municipality of Perugia, with the support of the National Committee for the Celebrations of the Eighth Centennial of the Death of Saint Francis of Assisi and a contribution from the Perugia Foundation, the exhibition will present more than eighty workscomprising paintings, drawings, etchings, sculptures and printed volumes by some of the most famous artists from Italian and European art history, such as Pisanello, Michelino da Besozzo, Paolo Uccello, Jan van Eyck, Fra Angelico, Piero della Francesca, Leonardo da Vinci, Leon Battista Alberti, Albrecht Dürer, Lorenzo Lotto, Dosso Dossi, Giambologna, Jan Brueghel the Elder, Domenichino, Annibale Carracci, Nicolas Poussin, Salvator Rosa, Giambattista Piranesi, Jean-Baptiste Camille Corot and many more, whose masterpieces are milestones that mark the crucial changes in how the figurative arts tackled and reflected man’s relationship with Nature in the course of the centuries.
The aim is to furnish a profound, evocative account of the diverse nuances with which Creation has been observed by human sensitivity and interpreted in artistic vision.

“With this undertaking, the National Gallery of Umbria stands confirmed as a museum on an international level capable of building a dialogue with other leading museums in Italy and abroad”, states Costantino D’Orazio. “This process of networking not only contributes to maximising the value of our collections, but is also capable of stimulating studies and research projects that will offer visitors an experience that speaks to everyone, one where they will all find plentiful reasons for coming back and recommending us to their friends and acquaintances.”

THE MASTERPIECES ON SHOW

The most significant works on show in Perugia will include the formidable 

Last Judgement by Fra Angelico, on exceptional loan from the Museum of the Basilica of San Marco in Florence, while the Gallery of the Accademia in the same city will be sending the enigmatic 


Thebaid by Paolo Uccello, here also accompanied by the Predella with the Miracle of the Profaned Host from the National Gallery of the Marches in Urbino, also by Paolo Uccello.

From the Galleries of the Accademia in Venice will come the celebrated 



Saint Jerome by Piero della Francesca, which will dialogue with the same subject painted some fifty years later by 



Lorenzo Lotto, now usually housed in the Castel Sant’Angelo in Rome.





Four drawings by Pisanello (from the Louvre) will detail the approach to nature of this great exponent of international Gothic art, a pioneer among artists for his scientific observation.



Michelino da Besozzo’s Madonna of the Rose Garden, an iconic version of nature depicted as unreal in its perfection, will illustrate late Gothic figurative culture. 

Just a short while afterwards, yet already in the full flush of Humanism, come the fundamental volumes of Leon Battista Alberti’s De PicturaLuca Pacioli’s Summa de aritmetica and Piero della Francesca’s De Perspectiva pingendi, triggering an epoch-making revolution by codifying the perspective system as a means to achieve a realistic representation of space. 

There will be a special focus on Leonardo da Vinci’s Codex Atlanticus, with two sheets being loaned to Perugia by the Ambrosian Library in Milan, to investigate the maestro’s contribution to the study of the flight of birds, both through his observations of nature and through his reconstruction of flight in the form of a machine.

The role of Francesco Colonna’s Hypnerotomachia Poliphili will be to tackle the theme of the symbolic value of natural elements, which was also explored by such artists as 


Dosso Dossi, with his Melissa from the Borghese Gallery in Rome, 



Paris Bordon, with the Holy Family with Saint John the Baptist from the Brukenthal Museum in Sibiu, 


Federico Barocci, creator of an emotional rendering of the Saint Francis Receiving the Stigmata, which will come from Fossombrone, and 



Correggio, whose Portrait of a Man Reading will be loaned by the Sforza Castle in Milan.


Visitors will then be immersed in idealised visions of nature as seen in the works of champions of classical and Baroque painting, from 

Annibale Carracci, with his Vision of Saint Eustace, to 

Giovanni Lanfranco’s Assumption of Magdalena, from the Museum of Capodimonte in Naples. 

The pivotal moment of the advent of a modern approach to the natural sciences, in the classification of living species (including the ones found in the New World), will be illustrated by the passage from the collections typical of the Wunderkammer, or Cabinets of Curiosities, to the publications of Ulisse Aldrovandi, while the scientific and astronomical discoveries of the early seventeenth century will be represented by the exceptional manuscript of the Sidereus Nuncius by Galileo Galilei, which is now preserved in the Central National Library in Florence.


There will be a rich section investigating nature as it is represented in landscape painting from the seventeenth to the nineteenth centuries, featuring works of artists of enormous importance to art history, such as Nicolas PoussinWilliam HamiltonDonato Creti – with two exceptional loans from the Vatican Museums – Claude Lorrain and Giambattista Piranesi, culminating in the exhibition’s finale, entrusted to the 

Marmore Waterfall (Waterfall at Terni), painted by Jean-Baptiste Camille Corot.

THE SECTIONS OF THE EXHIBITION

The visit to the exhibition will start with an investigation of Mother Nature, the generous earth, as modelled by the labour of man, whose depiction starts from the remotest centuries of the Middle Ages, progressing through the cycles of the months and the activities that take place in them.
An extensive section will be devoted to the representations of Creation, in other words Nature construed as the space occupied by mankind, where the divine will stands revealed. As the Middle Ages evolved into modernity, landscape and views acquired the status of autonomous genres, as the method of linear perspective and of the central vanishing point was devised and subsequently fully theorised.
In addition to their sensitive manifestations of Creation, artists allowed themselves to be seduced by oneiric, imaginative visions of a nature that was impossible in its perfection or its monstrosity. Scenarios of wonder accompany their reproductions of Eden or of the Kingdom of Heaven, for example in Michelino da Besozzo’s Madonna of the Rose Garden and in the Paradise in Fra Angelico’s Last Judgement.

The most enigmatic aspects of Nature will be analysed by an entire section of the exhibition, which sets out to investigate man’s inner turmoil when faced with indomitable, overpowering forces, as his reverential fear of the fury of the elements typical of mediaeval sensitivity gave way to the sense of bewilderment, terror and tension towards infinity when faced with Nature of the nineteenth century, which experienced the last, intense period of great landscape painting.

Throughout the exhibition will run a transverse thread that concentrates on the animal kingdom, whose dignity as a living, sentient creature was recognised for the first time, thanks to Saint Francis. In mediaeval figurative culture, it was because of the most celebrated episodes from the saint’s life – his Preaching to the Birds and the Taming of the Wolf of Gubbio – that these creatures ceased to be iconographic attributes, abstract symbols of vices or virtues, or figures playing mere walk-on parts instrumental to a narrative, to become leading characters in the story.

The experience found in the National Gallery’s immersive room will focus on the Canticle of the Sun, which the public will be able to explore, so as to rediscover the meaning of this masterpiece: a prayer, but also an ode to the sublime beauty of Nature, just as it is portrayed in the works on show in the exhibition.

The exhibition will be accompanied by a catalogue published by Moebius, with essays by the exhibition’s curators and numerous other scholars (Costantino D’Orazio, Davide Rondoni, Sofia Menconero and Leonardo Baglioni, Giacomo Calogero, Veruska Picchiarelli, Carla Scagliosi, Lucia Corrain, Giuseppe Cassio), whose aim is to investigate and develop on one of the most fascinating, yet still partly unpublished, episodes in art history

Modern Art and Politics in Germany 1910–1945: Masterworks from the Neue Nationalgalerie, Berlin

 The Kimbell Art Museum 

 March 30–June 22, 2025

Also:

Albuquerque Museum

Minneapolis Museum of Art

Further stops will be announced. 

This exhibition brings together more than seventy paintings and sculptures from the collection of the Neue Nationalgalerie, Germany’s distinguished modern art museum. It traces the German experience in the visual arts from the last years of the German Empire, World War I and the liberal Weimar Republic that followed to the rise of National Socialism and Adolf Hitler, the Holocaust, and World War II. Paintings and sculptures by artists including Max Beckmann, Otto Dix, George Grosz, Hannah Höch, Wassily Kandinsky, Ernst Ludwig Kirchner, Paul Klee, Käthe Kollwitz, Gabriele Münter, and Christian Schad show how modern art played an important role in the discourse during these critical decades in twentieth-century political history and how politics, at the same time, influenced the visual arts. Most of the works on view in this exhibition have never before been shown in the United States. 

“This is the first special exhibition ever held at the Kimbell devoted to painting and sculpture in Germany during the fraught, tumultuous first half of the twentieth century,” said Eric Lee, director of the Kimbell Art Museum. “We are grateful to the Neue Nationalgalerie, Berlin for the opportunity to provide this experience in Texas.”

The exhibition leads visitors through the great shifts in art and politics that took place between 1910 and 1945 in six thematic sections, beginning with Expressionism. In the first decade of the twentieth century, artists challenged the status quo of German art, painting and sculpting roughly drawn and vividly colored works. The Expressionists’ works were political in their objection to the conservative taste of their times, and specifically that of Kaiser Wilhelm II. Many German Expressionist artists were given prominent places in German museums in the wake of the first World War but were later often banned under Hitler. This gallery will include Ernst Ludwig Kirchner’s Self Portrait with a Girl, 1914-15, and Emil Nolde’s 1909 Pentecost, among paintings by other influential artists.

The next section features the Neue Sachlichkeit (New Objectivity), a movement that typified the modern style of the 1920s. These artists rejected the seemingly crude brushwork and dissonant colors of Expressionism, seeking to adapt to a new post-war social order in the liberal climate of the so-called Weimar Republic, the democratic government that was ushered in at the end of World War I and lasted until Adolf Hitler seized power in 1933. Their paintings were often marked by careful draftsmanship, sober brushwork, and a kind of hyper-realism that gave a modern interpretation of the traditions of German Renaissance art. This section includes works by artists who may be less well-known to American audiences but who have long been celebrated in Germany and recognized by artists and historians worldwide. Among them are Kate Diehn-Bitt, Kurt Günther, Franz Radziwill, and Christian Schad, whose 1928 painting Sonja is among the most famous icons of the movement. 

From this rediscovery of realism, museum visitors move to galleries featuring the International Avant-Gardes that found favor in the 1910s and ‘20s, when modern art from across Europe was exhibited in Germany. At this time, more than ever before, art from abroad was featured in museums and commercial galleries. In this exhibition, portraits of three influential art dealers will join works by the foreign artists they promoted: Afred Flechtheim by the painter Otto Dix; Herwarth Walden by the sculptor William Wauer; and Heinrich Thannhauser, in the painting by Lovis Corinth from the Kimbell’s own collection. This section of the exhibition includes works by such European artists as Pablo Picasso, Fernand Léger, Oskar Kokoschka, and Marianne von Werefkin. 

The exhibition next reveals ways that Modes of Abstraction entered and influenced German art in the years between the world wars. For example, the Cubism of Picasso, Georges Braque, and Léger exerted a strong influence in Germany, on painters such as Lyonel Feininger, Paul Klee, Gabriele Münter, and Georg Muche, whose works are displayed here. Feininger, Klee, and Muche were on the faculty of the Bauhaus, the famed art school, along with Wassily Kandinsky, and Oskar Schlemmer, also featured in this section of the exhibition. 

Politics and War demonstrates how artistic movements engaged directly with modern society and, by extension, with political issues. Some artists did so quite explicitly: George Grosz, in his famous 1926 Pillars of Society, blatantly ridiculed the establishment—political, military, and religious. The works in this gallery plot the course of events that led from Germany’s defeat in 1918 to the rise of militant nationalism in the 1930s, to a second world war, and to the Nazi atrocities that shocked nations worldwide. Examples include Wilhelm Lehmbruck’s mournful bronze sculpture Fallen Man, and Horst Strempel’s magnum opus, Night Over Germany, a denunciation of the Nazis’ barbarism in the form of a Christian altarpiece.

The exhibition concludes with an epilogue titled Before and After. This gallery includes works by some artists who had been exiled, who had been labeled as “degenerate,” or who were otherwise grappling with the political and humanitarian realities of post-war Germany, from the point of view of their art before the war and their history in the post-war era. Among the works seen in this concluding chapter of the exhibition are Max Beckmann’s melancholy 1942 Self Portrait in a Bar and Salvador Dalí’s Portrait of Mrs. Isabel Styler-Tas, painted in exile in Beverly Hills, California, in 1945. 

“The works in this exhibition are powerful, masterful,” said George T. M. Shackelford, deputy director of the Kimbell Art Museum. “And the stories that they tell about their turbulent times are gripping.”
