CHAPTER 1
Cloud Studies
THE VISIBLE INVISIBLE
A cloud is a visible aggregate of minute particles of water suspended in the atmosphere.
āThomas Forster (1815)1
Cloud is a body without a surface but not without substance. . . . Although it has no surface, cloud is visible.
āHubert Damisch (2002)2
Clouds have always fascinated sky watchers: forming, spreading, massing, dissipating in streaks and wisps; glowing at sunrise and sunset; processing lazily or purposively across the sky. Weighty and substantial bodies of minute droplets, they mysteriously combine visibility and volume without surface. Are clouds objects? Are they phenomena? The story of the āinventionā of clouds has been told by Richard Hamblyn, and the dramatic rise in the popularity of cloud-spotting suggests that they hold more than meets the eye.3 The principles of cloud formation were first understood in the early nineteenth century, when Luke Howard produced his classification of clouds as part of the embryonic science of meteorology. Driven by the turbulence of high-altitude winds and storms, bearing moisture or volcanic dust, cloudsāwe now knowāform part of a global weather system. For artists and poets of the Romantic period, they also provided a metaphor for mobility and transformation. Shelley found in clouds a swift-moving image of constancy-in-changeāāI change but I cannot dieā (āThe Cloud,ā l. 76). But he was a scientist as well as a poet, and his cloud behavior was based on the taxonomy of Luke Howardās early nineteenth-century Essay on the Modification of Clouds (1804).4 The sky, then, was more than a poetic workshopāit was a mobile laboratory for the study of airborne water.
Clouds draw the eye upward: to movement, distance, and height, to the dynamics of space and the overarching sky. For most of us, they provoke ideas about both transcendence and inwardness. When we look up, we lose ourselves. Clouds are associated with cosmology, but also with inner states. It is this combination of indeterminacy, space, and interiority that particularly interests me here. Clouds, I want to argue, make us think not only about form and vacancy, mobility and change, but also about the peculiar realm of affectivity that we call āmood.ā Whether we feel uplifted or depressed, we tend to take the ups and downs of internal states for grantedāso much so that we scarcely notice them. Mood is like the weather, changing and unformed, yet always with us. In classical landscape painting, weather and mood tend to converge on the drama of the sky. A cerulean sky spells calm; dark clouds indicate tempestuous events or passions. But in temperate climates, we most often experience an in-between state that is subject to subtle fluctuations of brightness and shadow, transparency and opacity. Englishness, and especially English landscape, has everything to do with changeable weather and the presence of atmospheric moistureāwith updrafts and downpours, bursts of sunshine, sudden rain showers, clouds and mists. For cloud painters like Constable, this environment formed what his first biographer called āa history of his affections,ā at once embodied and transient: āno two days are alike, nor even two hours.ā5 It is no accident that the most detailed account of Constableās cloud studies is by the meteorologist John Thornes.6
The object of keen meteorological observation during the Romantic period, clouds paradoxically serve to abolish the representational realm altogether. Goethe, in the series of poems inspired by his reading of Howardās early nineteenth-century classification of clouds, wrote: āIch muss das alles mit Augen fassen, / Will sich aber nicht recht denken lassenā (All of this I have to take in with my eyes, / But it will not let itself be grasped by thought).7 Goetheās clouds offer a way to represent the mind to itself; however minutely or evocatively described, they evade the grasp of thought, much like the mind. The sky extends the mental sublime into the realm of clouds or thought.8 In the landscape of Kantās sublime, nature represents the mind by analogy while also manifesting that it has a mind of its own. Wordsworthās poetry works on us because we recognize in his cloud landscapes a representationāat once natural and transcendentalāof how there is always more than the mind can grasp in nature, as well as in the imagination (just as in the Snowdon episode of The Prelude a sea of cloud usurps a real sea). Looked at from the point of view of a more recent taxonomy, clouds verge on the aesthetic of indeterminacy known as ālāinformeā (a potent invention of twentieth-century modernism) and hence on chaos and shapelessness.9 They thus lend themselves to being thought about in the philosophic domain that the phenomenologist Merleau-Ponty calls āthe visible invisible.ā10 Clouds are confusing, not so much because they mix elements or constantly change shape, but because they challenge the phenomenology of the visible with what cannot be seen: the luminous opacity associated with the phenomenology of sight.
What Thomas Forster (the nineteenth-century cloud scientist who most directly influenced Constable) called the ānubific principleā can also be read as a principle of painting.11 Viewed as a signifier, clouds have given rise to at least one counterhistory of painting. Hubert Damischās study A Theory of /Cloud/ (1972) makes /cloud/ the sign of paintingās paradoxical combination of the ephemeral and the material. Above all, it signals the escape of painting from the dominance of perspective and its historical transformation; the problem of surface became the problem of illusion. By the use of two forward slashes, Damisch transforms a word denoting ācloudā in any simple descriptive, referential, or figurative sense into an index or signifier.12 Enslaved to linear perspective (so Damisch argues), painting seeks another way to represent visual experience. /Cloud/āwhether rendered as the absence of sky or as deceptive trompe lāoeilāposes an alternative to the linear order. It becomes a sign of all that painting has to overcome. Instead of organizing the limits of a flat surface, the illusionistic clouds of the painted baroque cupola overflow their architectural frame. Correggio, according to Damisch, was the first to construct his pictures from the point of view of a Kantian subject for whom space is a constitutive aspect of consciousness.13
Damischās semiotic analysis of pictorial production takes the theme and texture of /cloud/ as an indexical case study for the development of painting; his /cloud/ becomes the defining problematic of painting from the baroque to the present day. This āpictorialā or āpainterlyā spaceāwhat he calls āa free and unlimited depth, considered as a luminous and aerial substanceāāis opposed to a modernist emphasis on linear style, with its flatness and overlapping forms. /Cloud/ is the sign of the volume repressed by modern paintingās fixation on the flatness of the representational surface. Its semiotics challenge the insistence of twentieth-century modernism on the representation of painterly space. Clouds round out pictorial space instead of flattening it; they point to the organization of the pictorial as a dialectic of surface and depth. /Cloud/ negates solidity and shape. Nebulous and indefinite, it signals an indeterminate volume, defying the medium and restoring painting to the realm of illusionistic space. But /cloud/ also contains the paradox of form which signifies itself.14
It may be a stretch to connect the vertiginous spaces of Correggioās painting to Constableās scientifically informed descriptive cloud studies, with their particularities of time, date, and weather conditions. But this connection is crucial to Damischās argument, and it will also inform mine. The painterly aspect of Constableās clouds serves as a reminder that even the most local and descriptive of painters can simultaneously strive for the dynamics of abstraction. Whether inspired by the flat Suffolk landscapes of his rural childhood, where his father was a prosperous miller (and both wind and water powered the mills), or by the views from airy Hampstead Heath overlooking London, where he spent his professional life, Constable had read meteorologists such as Forster, if not his precursor, Luke Howard. His cloud studies record the formation and transformation of clouds in response to the air and wind, for which Hampstead, high above the city, provided a perfect viewing point. But like Monetās water lilies, the series of Hampstead cloud studies that Constable painted during 1821ā22 can be understood as a painterās reflections on problems of depth, space, and form. His records of transient weather effects involve a painterly immersion, in air rather than water. Clouds are notoriously hard to draw not only because they change and move but because of their technical demands. Their challenge to graphic techniques and media, and their association with the brush, make them a theme especially suited to ink wash, watercolor, and rapid oil sketches. Cloud studies require attentiveness to subtle gradations of color and volume, along with swift, fluid, confident, and improvisatory technique.
Clouds are to outline as color is to drawing: like Rothkoās fields of color, they oppose line. Cloud studies also resemble the early nineteenth-century Romantic lyricāthey record the moment as a rapid or imperceptible succession of feelings and thoughts. Clouds mount, mass, tower, or darken. They provide a barometer of feeling. As Constable famously wrote in a letter to his friend and patron the Reverend John Fisher in October 1821 (the period of his Hampstead cloud studies), āpainting is but another word for feeling.ā In the same letter, he added that the sky is not āa āWhite Sheetā drawn behind the Objectsā (like the backdrop to a painted scene) but rather āthe ākey noteāāthe standard of āScaleā and the chief āOrgan of Sentiment.āā15 Clouds, for Constable, were a source of feeling and perception, an āOrgan of Sentimentā (like the heart or lungs) as much as meteorological phenomena. If painting is another name for feeling, and the sky an organ of sentiment, then his cloud studies are less a notation of changing weather effects than a series of Romantic lyrics: exhalations and exclamations, meditations and reflections, loosely attached to a specific location or moment in time. Constableās skies may sometimes lend themselves to allegory, as in the rain cloud and rainbow over Salisbury Cathedral or the storm clouds that lower dramatically over Old Sarum.16 But more often, they evoke fleeting states of mind, feeling, and atmosphere. As they mount or move across the sky, they become a language for inner activity: darkening here, lightening there, here an ascent, there a fraying or an accumulation of intensity; a passage of calm before a storm or a glimpse of cerulean sky.
Constableās cloud studies express states of mind that are elusive and transient, yet their movement and rhythm evoke the familiar play of light and shadow across a landscape. Clouds have a directional tendency, traveling on what are, incongruously, known to meteorologists as āstreets,ā as if they were traffic. Constableās cloud studies catch something as indefinable yet ever present as our own internal weatherātendency and mobility. How better to register the constantly shifting relation between perception and feeling, embodied consciousness and underlying emotional states? The sky, then, functions both as an organ of sentiment and as a form of nonreferential free associationāas both visibility and invisibility, form and lāinformeābut above all as a mode of perception. But clouds also carry a material freight along with their aesthetic and emotional connotations. We should not lose sight of the great nineteenth-century changesāat once scientific and industrialāthat formed clouds as we know them. Before coming back to Constable, I want to turn to his early nineteenth-century contemporary: the Northamptonshire laborer-poet, John Clareāfamous for his poetry of detailed natural observation, for his madness, and for his long confinement in mental institutions. Clare, I want to suggest, not only observed nature minutely but also saw more than he knew, and perhaps knew more than he could actually see. This is especially evident when it comes to Clareās clouds.

āUnder a Cloudā
& we often see clouds which we identify by their curling up from the orison in separate masses as gass clouds which ascend into the middle sky & then join the quiet journey [of the] clouds & are lost in the same colour.

John Clare, adrift on a cloud journey, also experienced his depressions as being āunder a cloud.ā18 In what is probably his most famous po...
