The career of American conceptual artist Roni Horn spans nearly five decades of rigorous investigation into the nature of materials, perception, and identity.
Yet across the multifaceted dimensions of this practice—sculpture, photography, drawing, and installation—a single subject has emerged as the central preoccupation: water. For Horn, this most ordinary and essential element embodies the fundamental paradoxes that animate her artistic thinking.
"The thing that's most compelling about water is that it exists in so many different states and forms," Horn explained in a recent interview about her current exhibition at the Museum of Contemporary Art Denver, the first dedicated entirely to her exploration of water.
"This is an extraordinary medium, but also spiritually, it's essential to my well-being." Water appears throughout her oeuvre not as a literal subject matter alone, but as a conceptual framework through which questions of identity, materiality, and transformation can be articulated.
Horn's philosophical engagement with water begins with a paradox that has captivated her thinking for decades. Water exists as a verb rather than a noun—not as a static thing unto itself, but as something fundamentally relational, experienced only through its interaction with other things. The substance is completely dependent; its shape is determined entirely by its container, whether that be a river, a glass, or the earth itself.
Yet despite this radical dependence, water maintains an uncanny constancy. "The water you drink—who knows how many times it's been around the world—and still its appearance is wildly constant," Horn stated. Water achieves an identity with an endlessly changing appearance. It achieves this through what Horn calls a "pure paradoxical form."youtube
More specifically, water achieves purity through a process of contamination. Horn has noted that naturally purified water is literally filtered through everything—through dirt, impurity, and the material world.
"It seems to be a pure paradoxical form, to achieve this degree of crystal purity by intermingling itself with all of this dirt and impurity," she reflected. This paradox—that water becomes transparent and pure not through isolation but through intimate mingling with everything else—becomes a philosophical anchor for much of her artistic production.
Since first visiting Iceland in 1975, shortly after graduating from the Rhode Island School of Design, Horn has returned frequently to the island to pursue her investigation of water in its various manifestations.
Iceland's landscape offers an ideal site for this meditation: the island is defined by water in nearly every form—geothermal pools, glaciers, waterfalls, rivers, and the surrounding Arctic Ocean. Horn obtained Icelandic citizenship in 2023, a formal recognition of her lifelong relationship with the country and its elemental character.
The transformation of water from one state to another provides endless material for Horn's visual thinking. She speaks about water with an emotional vocabulary—it can be serene, troubled, volatile. More significantly, she is "equally entranced by its capacity for violence," the way it can destroy as well as sustain.
Icebergs fascinate her precisely because they represent water in what appears to be its absolute opposite form. "The experience of large icebergs is one-of-a-kind, and really the apparent opposite of water in every way, visually," Horn noted. "I love that mask water puts on—it's not hiding anything, it's just another expression of itself."
This philosophical framework finds its most challenging material realization in Horn's cast-glass sculptures, which she has pursued since the mid-1990s. These monumental works, weighing as much as five tons, appear at first glance to be transparent containers filled to the brim with liquid water.
In fact, they are entirely solid—masses of glass poured extremely slowly, over periods of 24 hours, into molds designed to achieve immaculate surfaces and precise hues. Thousands of pounds of viscous molten glass are cooled gradually over months to avoid air bubbles and impurities, with the top naturally forming a highly polished surface that mimics water held by surface tension.
These sculptures embody the conceptual perversity that characterizes Horn's entire artistic project. Glass, like water, exists in a profoundly ambiguous state. Technically, glass remains a supercooled liquid—a material that refuses to choose decisively between solid and liquid states of matter.
The sculptures shift and transform according to surrounding light, weather, and the viewer's position. What appears in morning light differs fundamentally from what the same work reveals in afternoon. Horn describes this quality as a watery "oculus"—a window onto instability itself.
The sculpture series titled "Water Double" exemplifies this conceptual approach. One version pairs a blue glass form resembling an iceberg with a black glass counterpart suggesting black ice—different faces of the same elemental phenomenon, each evoking distinct emotional and physical associations.
The massive weight of these pieces, combined with their apparent fragility and transparency, creates what Horn describes as a paradoxical presence: objects that are simultaneously massive and delicate, opaque and transparent, solid and fluid.
Beyond sculpture, Horn has explored water through extensive photographic series and books. "You Are the Weather," created between 1994 and 1995, consists of 100 close-up photographs of the same woman's face, documenting subtle shifts in appearance as she reacts to different atmospheric and lighting conditions in Iceland's natural hot springs.
The work invites meditation on how external circumstances shape perception of identity. More recent work continues this investigation: "You Are the Weather, Part 2" comprises 100 photographs of Icelandic artist Margrét Haraldsdóttir Blöndal, shot over six weeks across various geothermal pools, capturing the subtle variations in expression as changing light and water conditions transform the face.
Horn's photographic work "Still Water (The River Thames, for Example)" applies water-based meditation to the urban landscape. The series presents 80 photographs of the Thames annotated with handwritten footnotes that offer the artist's philosophical observations.
These notes transform the documentation of water into a form of poetic reverie, conveying what Horn describes as a "manic, obsessive, endless flow of consciousness." The Thames becomes not merely a river but a repository for human history, meaning, and contradiction.
The most ambitious realization of Horn's thinking about water materialized in her design of Vatnasafn/Library of Water, completed in 2007 in Stykkishólmur, Iceland. Housed in a converted library building overlooking the North Atlantic, this permanent installation contains 24 glass columns, each filled with water originally sourced from one of Iceland's major glaciers.
The floor is covered with a rubber mat inlaid with words describing weather in both Icelandic and English. The work functions simultaneously as archive, memorial, and community space.
The Library of Water operates as an archive of loss and transformation. When Horn conceived the installation, it was a repository of glacial ice samples collected from across the country.
Yet as climate change accelerated glacier retreat, the ice has melted entirely, and the columns now contain only water—a physical manifestation of environmental transformation. The work documents not what was, but what remains after vanishing. It preserves absence.
Horn's extended series of books titled "To Place" (beginning in 1990) develops the relationship between water, identity, and landscape through photography, text, and drawing.
These volumes constitute what some describe as an encyclopedia of Iceland's geography and emotional terrain, each focused on different aspects of the island—folds in the landscape, pools and hot springs, rivers and waterfalls, the face of individual Icelanders. The books convey what one observer called "the quiet intensity and subtle energies of a long communion between an elemental island and an enquiring mind."
Horn's artistic method involves what she describes as "drawing" in a conceptual sense—drawing as "composing relationships" rather than as a conventional technique. Her installations frequently employ doubling and repetition as visual and conceptual strategies.
She positions identical or nearly identical works on opposing walls or in adjoining rooms, forcing viewers to navigate between them and discover variations through sequential experience. This methodology extends the modernist preoccupation with perception into a philosophy of identity itself—the recognition that identity is never fixed or autonomous but emerges through relationship, circumstance, and temporal experience.
In her recent statement on water, Horn articulates an understanding of the element that encompasses scientific observation, philosophical inquiry, and personal experience. Water is at once the most transparent and most opaque substance—transparent in its physical composition yet endlessly complex in its manifestations and meanings.
It refuses definition while maintaining constancy. It depends entirely on circumstance yet retains identity. These paradoxes are not obstacles to be resolved but the very condition through which authentic artistic thinking becomes possible.
The current exhibition at MCA Denver, "Water, Water on the Wall, You're the Fairest of Them All," brings together works spanning decades, from photographic series to monumental glass sculptures to annotated drawings. The exhibition takes on particular resonance in the American West, where water scarcity defines contemporary politics and ecology. Yet Horn's work resists reduction to environmental commentary.
Instead, it offers a framework for thinking about water—and by extension, identity, materiality, and perception—as fundamentally paradoxical. In a world increasingly defined by certainty and quantification, Horn's insistence on water's irreducible complexity, its simultaneous dependence and autonomy, its transparent opaqueness, suggests an artistic practice oriented toward what she calls "giving back" to materials their full corporal presence and mysterious potential.
Water, in Horn's conception, is never merely the subject of art. It becomes the very model through which art thinks—through transformation, through refusal of singular meaning, through perpetual becoming.
This is why Horn's obsession with water endures across decades and media: it is an obsession with art itself as a form of consciousness perpetually in flux, dependent on circumstance, achieving clarity through contamination, maintaining identity through endless variation.
