Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST Pareidolia and the Pitfalls of Subjective Interpretation of Ambiguous Images in Art History Raquel G. Wilner (art historian, independent researcher), Courtauld Institute of Art, Somerset House, Strand London WC2R 0RN, United Kingdom. Email: © ISAST Manuscript received 15 January 2020. Abstract In art history, we sometimes discover hidden images within a picture and conduct a subjective introspective analysis on the painter’s motivation behind these images. I argue that many such highly ambiguous hidden images are better explained by the pareidolia phenomenon: the tendency to find patterns in random stimuli. The arguments brought forth by Sidney Geist and Dario Gamboni illustrate the pitfalls and controversy of subjective visual analysis and how a perceptual phenomenon can mislead our conclusions. This paper proposes that this controversy can be approached by establishing pictorial intent: did the artist deliberately paint the hidden image, or is it merely a perceptual artefact? Sometimes artists make use of perceptual phenomena to create ambiguous images within their pictures. An example is Salvador Dali’s Slave Market with the Disappearing Bust of Voltaire (1940), where two women, a man’s back, and a background archway together form the shape of Voltaire’s head. In psychology, this is called a figure-ground relation of visual perception, or a reversible figure, and our attention is limited to perceiving one image in Slave Market at a time [1]. This face identification relates to a perceptual phenomenon called pareidolia: a tendency to perceive patterns in visual and auditory stimuli when those patterns only coincidentally produce a familiar configuration, such as seeing faces in clouds or animals in rocks (Fig. 1). It is similar to the gestalt phenomenon, which involves seeing wholes based on the sum of its parts. However, unlike gestalt designs, pareidolia effects are always coincidental. The pareidolia phenomenon has become a popular occurrence on the internet, with people finding faces in a variety of objects ranging from bread to sinks [2]. This occurs because our brains are constantly attempting to make sense of our perceived environment, even to the point of creating illusory patterns and connections [3]. Pareidolia occurs because of a tendency to find false positives, a possible survival mechanism that has evolved through natural selection [4]. Fig. 1.

Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST Pareidolia and Art History Art history is no stranger to illusion, but the concept of pareidolia appears to have largely escaped art historians [5]. The term was first coined by Karl Ludwig Kahlbaum in 1866 [6]. Older descriptions of pareidolia can be found in Alberti’s On Painting [7], who writes: ‘They probably occasionally observed in a tree-trunk or clod of earth and other similar inanimate objects certain outlines in which, with slight alterations, something very similar to the real faces of Nature was represented… (p. 9).’ Leonardo da Vinci also described seeing figures and landscapes on wall stains and stone [8] and in Shakespeare’s Hamlet the characters see animals in clouds [9]. Pareidolia is most commonly associated with perceiving faces. This occurs because our brains have a unique facial processing system, which has evolved over 30 million years, and anything even remotely face-like will activate it [10]. In fact, an area of the brain called the fusiform gyrus brain area activates both when we see an actual face and when we experience a pareidolia effect [11]. We initially recognize a stimulus as a face by identifying its key features: eyes, mouth and nose, which our perceptual system puts together into a whole [12]. In Arcimboldo paintings, which are pictures of objects such as fruits and vegetables that together create a portrait of a person, spectators focus on the ‘eyes’. [13]. Similarly, focus is on the faces in Ilya Repin’s An Unexpected Visitor (1884-1888), particularly the eyes and mouths [14]. Artists are an interesting exception to this rule, and tend to look more freely around without showing any noticeable emphasis on faces [15]. We also appear to be biased towards finding faces: in one study, 39% of participants claimed to see faces in randomly generated images of static white noise [16]. Pareidolia helps explain why we sometimes see a face in a painting and wonder whether the artist put it there deliberately. There is no doubt that the reversible images in Slave Market were put there intentionally, particularly because the title primes the viewer to find them. However, because our brains are tuned to look for such images in all stimuli, it follows that we may also detect patterns or hidden images in ambiguous pictures where the artist’s intention is not known. Sometimes the premise behind discussions on such ambiguous images is the presumption that it was deliberately placed there by the artist. This could potentially lead to wrongful conclusions, as the image may simply be a perceptual artefact. I will illustrate the pitfalls of such interpretations through the approaches to ambiguous images by two authors, Sidney Geist and Dario Gamboni, who proposed that Paul Cézanne and Paul Gauguin, respectively, placed hidden images in their pictures either deliberately or unconsciously. Cézanne’s ‘Cryptomorphs’ In his book, Interpreting Cézanne, Geist [17] suggests that the artist unconsciously placed hidden portraits in his paintings, and he often attempts to justify these claims through circumstantial and ambiguous evidence from letters. The hidden images are called ‘cryptomorphs’ and are often hard to detect. A supposed hidden face is found in The Large Bathers (1906, Fig. 2): Geist claims the trees outline the hair, the top of the white cloud forms an eyebrow, with an iris underneath in the foliage, and the shoreline across the river is the mouth. Geist paradoxically believes this image was not consciously placed there, stating that the eye is ‘placed with Raquel G.

Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST anatomical precision,’ but also that ‘nothing that we know of Cézanne leads us to think that he willed it or knew that he made it [18].’ Fig. 2. Paul Cézanne, The Large Bathers (1906). Oil on canvas, 210.5 cm x 250.8 cm. Philadelphia Museum of Art, Philadelphia, USA. (Photo courtesy of Wikimedia Commons.) The alternative approach is that Geist is simply experiencing pareidolia when viewing Cézanne’s pictures, and that he perceives something face-like in the painting. This leads him to make inferences about the inner workings of Cézanne’s mind, where his unconscious is guiding his hand and planting hidden faces in his paintings without the artist being overtly aware of doing so. There are possible exceptions to Geist’s overanalysis of pareidolia effects, such as Poplars (c.1880, Fig. 3). Geist claims the title is very similar to the French word for people (peuple), and he sees the shapes of several human figures amongst the trees. Even if we accept that this play on words from Cézanne was deliberate, we do not need to find hidden images in the picture for the pun to work: the trees may act as metaphors for people, and not necessarily as literal depictions of them.

(Photo courtesy of WikiMedia Commons) Gauguin’s ‘Aspects’ Gamboni, like Geist, uses subjective analysis to find hidden images in Gauguin’s work, and substantiates these claims through letters the artist has written [19]. These ‘aspects’, as Gamboni calls them, allude to ambiguous images within images that take form, and are interpreted, in the spectator’s mind. Gamboni outlines many hidden aspects in Gauguin’s paintings, such as a supposed face between a tree and a bush in an untitled drawing (Woman and Child before a Landscape – c.1888-9), or how the leaves of two trees in View of Pont-Aven from Lézaven (1888-1889) form a face [20]. These hidden faces are best explained as accidental configurations perceived through pareidolia – or, as Gamboni states, in the spectator’s mind. One case of a hidden image is substantiated by technical evidence: the hidden portrait found in Gauguin’s Seascape with Cow on the Edge of a Cliff (1888, Fig. 4). The quasi-flattened foreground of this painting gives room to a confusing space. The hidden image appears to pop- out from the disjointed background, revealing itself in the water wedged between the cliffs. It is allegedly the profile of the artist facing towards our right: there is a long thin neck; a pointy chin (the artist’s beard); his iconic aquiline nose; and lastly, a beret at the top. In addition to its similarity to portraits of Gauguin, an X-ray of the picture implies that the artist had gone over it multiple times, suggesting intent [21]. Nevertheless, Gamboni also mentions that the two cliff sides look like two animal heads. The X-ray of the hidden portrait suggests intent, as the features Raquel G. Wilner, Pareidolia and the Pitfalls of Subjective 3 Interpretation of Ambiguous Images in Art History Downloaded from http://direct.mit.edu/leon/article-pdf/doi/10.1162/leon_a_02061/1894174/leon_a_02061.pdf by guest on 27 March 2021
Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST have been demarcated, but the same cannot be said of these other two heads. Consequently, the two images found in the cliff-sides are most likely artefacts of pareidolia. Techniques and the Unconscious in the Perception of Hidden Images Pareidolia is a more likely explanation for the ambiguous images in paintings by Cézanne and Gauguin, because most of the ‘cryptomorphs’ and ‘aspects’ are faces, complete with eyes, mouths and often noses. Geist and Gamboni’s unawareness of pareidolia can certainly be forgiven, but it also led them to make speculative claims about their respective artists [22]. The real question is not whether one perceives these hidden images, but rather whether they were intentionally put there or not, because this has consequences for the artist’s biography. By ‘intention’ I mean that the artist was overtly aware of what he painted – this necessarily precludes any unconscious intention. Our perceptual system allows us to perceive gestalt patterns and meaning in any stimuli, and thus any work of art, but these perceptions alone are not necessarily evidence of the artist’s intent. Fig. 4 Paul Gauguin, Seascape with Cow on the Edge of a Cliff (1888). Oil on canvas, 72.5 x 61 cm. Musée d’Orsay, France. (Photo courtesy of WikiMedia Commons.) James Elkins has alluded that ‘aleamorphs’ are images not made by human hands, while cryptomorphs are [23]. However, that something is human-made does not necessarily mean it is made with intent: the perceived image could, for instance, be the accidental result of a combination of brushstrokes. I argue that distinguishing between intention and accident in an Raquel G. Wilner, Pareidolia and the Pitfalls of Subjective 4 Interpretation of Ambiguous Images in Art History Downloaded from http://direct.mit.edu/leon/article-pdf/doi/10.1162/leon_a_02061/1894174/leon_a_02061.pdf by guest on 27 March 2021
Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST ambiguous image should be done by establishing pictorial intent [24], meaning it has been deliberately placed there by the artist, and is not a perceptual by-product. Pictorial intent could be difficult to establish, but can sometimes be reasonably assumed through supporting evidence such as letters, the title, subject matter and technical analyses. The absence of such evidence does not exclude the possibility that the image was deliberately placed there, but for the sake of remaining objective, I recommend a skeptical standpoint: ambiguous images within a picture should be considered a pareidolia effect (or ‘aleamorphs’) unless evidence suggests otherwise, else we run the risk of making highly speculative claims. Geoff Cole [25] argued that consequences are more important than author intent, because we can never directly see into the mind of the artist. Similarly, Gombrich argues that intent is irrelevant: what matters is what significance the image carries [26]. The point with ambiguous images within images, however, is that intent is not known, and our interpretation of the images can end up prescribing knowledge about the author and their psyche based purely on subjective perception. Arguably, pictorial intent is weakened if different people do not perceive the same configuration. For example, Joyce Medina [27] claims to see a skull in the void between the two figures depicted in Cézanne’s The Card Players (1894-1895), but due to its highly ambiguous nature it is likely a pareidolia effect. On other occasions, we might universally perceive the same figure, but this observation alone does not constitute evidence that the image was placed with pictorial intent. For example, Roger Caillous’s minerals resemble sceneries or people. The titles aid the viewer in finding these patterns, e.g. Le Petite Fantome (The Little Ghost). In this case, the ‘artist’ is nature itself, and it would be wrong to assume any intent behind the depiction. In terms of modern art, the brushstrokes of Cézanne and Gauguin possibly make their pictures more susceptible to pareidolia, primarily because they leave room for ambiguity. Color modulation is separate, with visible brushstrokes that create forms in themselves, thus not only do they form part of a whole, but they can also be viewed individually [28]. Some styles may be more suggestive in finding hidden images than others, such as abstract expressionism. Jackson Pollock’s work may evoke a myriad of different elements, where the ambiguity sparks subjective meaning in the spectator. Pictorial intent still applies: any hidden images should not be assumed to have been planted by the artist without objective evidence supporting this intention. Art is often layered with ambiguous meaning [29]. Subjective analysis and intent attribution are not meant to be discouraged, as they have a place in art history. The proposed concept of pictorial intent is a recommendation for art historians that encounter ambiguous imagery: it is not a general approach to art analysis, and should not supersede other art historical methods. Art is meant to express meaning [30], but it does not necessarily follow that the meaning we identify also provides autobiographical information about the artist. The Pitfalls of Subjectivity David Carrier acknowledged that even though Geist’s analyses were ultimately dismissed, at least it made art historians rethink Cézanne’s work [31,32]. However, artworks can be discussed and enjoyed in their own right, without a need to give them additional layers of meaning based entirely on subjective perception of questionable hidden imagery. As Elkins states: ‘The richness Raquel G. Wilner, Pareidolia and the Pitfalls of Subjective 5 Interpretation of Ambiguous Images in Art History Downloaded from http://direct.mit.edu/leon/article-pdf/doi/10.1162/leon_a_02061/1894174/leon_a_02061.pdf by guest on 27 March 2021
Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST and nuance of historical research are excised in favor of violently reductive interpretations, and the result is artwork that is less interesting than it had been [33]’. Fig. 5 Paul Gauguin, Parau na te Varua ino (1892). Oil on canvas, 92 cm x 68 cm. National Gallery of Art, Washington D.C, USA. (Author’s edit. Original photo courtesy of Wikimedia Commons.) Another danger with a subjective interpretation is confirmation bias: the tendency to look for evidence to support your own claims, rather than looking for evidence that could potentially disprove it [34]. Thus, when anyone has a hypothesis about hidden images in paintings, it becomes increasingly easier to spot such ‘images’, since they are actively looking for examples to confirm their suspicions. Gauguin’s Parau na te Varua ino (1892) highlights the whimsical and erratic nature of a person’s subjective interpretation, as there is reputedly a myriad of different faces in the depicted tree trunk [35]. We almost invariably find hidden images when we seek them: in the same ‘reptilian’ tree trunk there is a peached-colored patch in the middle that contains an anthropomorphic sinister face, which is even more prominent once mirrored and flipped (Fig. 5). Conclusion Pareidolia helps explain why we sometimes perceive hidden images within pictures, as illustrated by Cézanne and Gauguin. In rare cases, technical evidence, documents, the picture’s title or subject matter can support the suggestion that a hidden image was intentionally painted, such as in Gauguin’s Seascape. However, a single valid case is not proof that all other Raquel G.

Leonardo Just Accepted MS. https://doi.org/10.1162/ leon_a_02061 © 2021 ISAST ambiguous images by the same artist were placed with pictorial intent. Seeing hidden faces or other figures does not necessarily reveal anything about the intention of the artist, and any arguments regarding the artist’s motivations are based on the premise that the image was not accidental (circular reasoning), but such assertions require evidence. Subjective analysis certainly has a place in art history and it is not my intention to discourage any such endeavor, but its limitations should be recognized. Hidden and ambiguous images within images, fascinating though they may be, are plentiful when the artist employs a technique that creates ambiguity. Any conclusions drawn regarding the motivation or mind of the artist based on a subjective interpretation should be evoked carefully. Even AI image analysis could be misleading, as the analysis program was created by humans, although image analyzers could assist in objectively outlining e.g. demarcation in X-Ray scans. Relying on subjective interpretations of ambiguous images leads to seeking patterns where none exist, drawing connections with little or no basis, and building theories based entirely on speculation.
