“Art usually becomes a commodity. One of the implications of earth art might be to remove completely the status of a work of art and to allow the idea of art as…more of a religion. In that sense, it wouldn’t have a utilitarian function anymore.”¹
This From the Research Department chronicles Peter Freeman, Inc.’s most ambitious project in Switzerland to date: Michael Heizer’s largest publicly accessible artwork outside of the United States, Tangential Circular Negative Line (1968/2012). Located at the foot of the Mauvoisin Dam in the Val de Bagnes, the sculpture was commissioned by the Air & Art Foundation and Peter Freeman, Inc. facilitated its execution. Throughout his career, Heizer explored a set vocabulary of shapes and forms within each of his unique works, developing a gesture through different existences. Tangential Circular Negative Line repeats Heizer’s interlocking circle motif, created in 1968 and explored in multiple iterations across several decades. This is the third rendering of this exact configuration and his sixth circle work overall.

If one makes the trek into the Val de Bagnes region of the Swiss Alps, winding through the natural beauty of the Mauvoisin valley beyond pastures, forests, a one-lane bridge, and a small inn on an isolated dirt road, something unexpected comes into view: Michael Heizer’s only extant earthwork in Europe, Tangential Circular Negative Line (1968/2012). Consisting of three interlocking circles made of Corten steel recessed into the ground, the work measures 112 ½ by 75 feet and is surrounded by fill gravel, creating negative space. The largest circle, measuring 75 feet in diameter, dominates the composition; two smaller circles, identical in size at 37 ½ feet in diameter, each connect tangentially to the large circle, one within it and one outside it. In this case, “small” may be misleading, and yet, when compared to the enormity of the mountain range in the background, the sculpture appears restrained and balanced. Its monumental scale and sublime location recalls the artist’s late 1960s and early 1970s excavations in the Nevada deserts, which were similarly set against the expanse of nature. Perhaps what is most impressive about Heizer’s three rings is how they are situated: embedded within, yet fully integrated into a magnificent landscape of mountains, rivers, and ravines, creating a sense of harmony between the natural and manmade.
Heizer’s exploration of the complex relationship between man and nature captivated the Air & Art Foundation, a Swiss organization aiming to commission permanent public artworks that incite a dialogue between viewers and their environment. As of today, Tangential Circular Negative Line remains the only project realized by the foundation and would not have been possible without the support of Peter Freeman, Inc. The gallery’s decades-long relationship with Heizer began in 2003, when Peter Freeman, Inc. mounted a solo exhibition of his paintings, the first show of the artist’s work in New York in over a decade at the time. In 2008, Peter Freeman, Inc. organized the commission and fabrication of two large-scale sculptures, Collapse (1967/2008) and Compression Line (1968/2008), by Glenstone Museum in Potomac, Maryland. Tangential Circular Negative Line was the first international project that the gallery facilitated for the artist.

Over the course of his career, much of Heizer’s artistic practice focused on displacing, excavating, and manipulating natural landscapes, expanding the traditional definition of sculpture by emphasizing negative space over physical volume. He is widely recognized as the leading figure in the land art movement, which constituted a group of artists who strayed from traditional materiality, swapping canvases for dirt and painting for digging. Such a radical approach did not come out of nowhere; in the preceding decades, a clear trajectory can be seen from the overly exaggerated gestures of abstract expressionism to the spare, almost nonexistent ones in minimalism. One can continue this to land art, which at its most basic level embellishes mark making to such an extreme that it loses any sense of individuality. At its core, land art is a way to make a gesture not only onto a landscape but as large as a landscape, in turn creating its own environment. Since these works existed within outdoor areas outside of galleries and museums, they signified a shift away from how art was traditionally experienced. In order to encounter one of these sculptures, it was often necessary to travel outside major cities to remote locations. Once there, visitors are encouraged to walk around or even enter the excavated space, providing a far more immersive experience than a traditional art encounter. Heizer agreed with this, stating that “Art usually becomes a commodity. One of the implications of earth art might be to remove completely the status of a work of art and to allow the idea of art as…more of a religion. In that sense, it wouldn’t have a utilitarian function anymore.”¹

Heizer ventured to create a uniquely American art fully divorced from European art history.² To accomplish this, he devised his own visual language consisting of numerous shapes and forms that he would repeatedly explore across varying materials and circumstances. By 1968, at only 23 years old, Heizer had fully developed his vocabulary and embarked on a five-decade journey to explore how these marks could translate into art. Perhaps some of his practice can be traced to his upbringing as the son of a prominent archaeologist. At age 12, Heizer took a year off from school to accompany his father on a series of digs across Mexico, drawing the sites as his father excavated. There he encountered a form of language and communication that existed outside the history of Europe. This exposure to a world of monumental and primordial sites that have long outlasted their people inspired the artist’s lifelong interest in history, materiality, scale, and leaving an indelible mark during one’s lifetime. Thus his fascination with altering the landscape and exploring the way gestures could be indexed into the earth was born. Though Heizer was interested in doing so at a large scale, he has never felt his enormous works leave a significant impact: “Man will never create anything really large in relation to the world — only in relation to himself and his size. The most formidable objects that man has touched are the earth and the moon. The greatest scale he understands is the distance between them, and this is nothing compared to what he suspects to exist.”³

This line of thinking exemplified a set of uniquely American principles in the 1960s at the height of the Space Race. Heizer himself recognized this as the impetus behind the scale of land art, arguing that, “It was a question of an American sensibility, things were being done that felt uniquely American—a lot of them had to do with size—size and measurement.”⁴ Others agreed with this assessment—over a decade after helping inaugurate land art, British artist Alan Sonfist declared that “Art in the land is an American movement.”⁵ Even today, most of whom we recognize as progenitors of land art are American, such as Nancy Holt, Walter De Maria, and Robert Smithson. Though not a strictly American phenomenon, land art’s emphasis on immense scale underscores a pedigree of exceptionalism that defines the country: the belief of “the bigger, the better.” Heizer frequently discussed his work in such terms. When speaking about his colossal sculpture Double Negative, he equates it to American engineering achievements: “As long as you’re going to make a sculpture, why not make one that competes with a 747, or the Empire State Building, or the Golden Gate Bridge.”⁶

For many land artists, the Earth was viewed as both a vast wasteland and an empty canvas, malleable and subject to an act of man over nature. In this sense, land art became an outlet for many artists whose public image revolved around appearing rugged and masculine. Perhaps a holdover from abstract expressionism, the first “distinctly American style”⁷ of art, often associated with toughness, land art artists embraced “masculine” acts of art making, as the techniques needed to create such Herculean works often mimicked those in the mining and construction worlds.⁸ In addition to using simple tools such as shovels and hoes, they detonated explosives, drove trucks, and rode motorcycles. The fact that many earthworks were concentrated in the West, an expanse frequently romanticized and mythicized as an undiscovered frontier, only fed into this perception. Notions of the frontier hero became so pervasive in popular culture during the 19th century that Frederick Jackson Turner recognized the Western frontier as an underlying principle that shaped American identity and culture going forward into the 20th century.⁹ Heizer, in particular, leaned into this mythology in both his artistic practice and public image, often posing for photographs in denim, cowboy boots, and Stetsons against the backdrop of the vast desert.

Nevertheless, Europeans were not unfamiliar with the movement. Several European artists, including Sonfist, Jan Dibbets, and Richard Long are often placed in a separate category and did not subscribe to the ideals of their American counterparts. British sculptor Richard Long asserted that his “interest was in a more thoughtful view of art and nature, making art both visible and invisible…It was the antithesis of so-called American Land Art, where the artist needed money to be an artist, to buy real estate, to claim possession of the land and wield machinery.”¹⁰ While some of Long’s criticisms would be unfair to apply to Heizer, no one captured the American Spirit more than the outlaw cowboy of the art world. Michael Govan, the director of the Los Angeles County Museum of Art, argued that “There is nothing more powerful, romantic, and American than these gestures that in Mike’s case have taken his whole life.”¹¹ With these factors at play, how would Heizer’s “powerful” and “romantic” American work fit into a European setting without relinquishing its maverick ethos? Does his work translate effectively into such a context? How would such a uniquely American art form be viewed when interpolated into Swiss public life, and would it successfully foster a connection between man and nature?
Michael Heizer, Circular Surface Drawing (1968). 1.5 ton displacement of earth, 11 3/4 inches high x 95 5/8 inches diameter (30 cm high x 243 cm diameter), Mirage Dry Lake, Nevada
Despite the mythology surrounding him, Heizer’s impetus for travelling out West was merely for practical purposes, as he grew up in Nevada and was familiar with its landscape.¹² From his perspective, the only locations that could accommodate his large-scale sculptures were in the desert, where the land was unregulated and easily obtained. Nevada was a prime location for his works, as it was underdeveloped, desolate, and difficult to visit. Its natural materials, namely the unique sands and gravels that could be used make concrete, also attracted Heizer. In 1968, the year the artist solidified his visual lexicon, Heizer developed and executed his interlocking circle motif for the first time on Mirage Dry Lake, titled Circular Surface Drawing. To produce this experimental drawing, the artist shoveled out two 1,500-pound piles of backfill remnants from a previous earthwork out of a pickup truck while a driver steered in circles. Such a simple act of displacing earth and assessing its resulting imprint appeared to be a study for something much larger, as its end result seemed uncontrolled and imprecise in a way that Heizer usually was not. Because of this, it was never intended to have been viewed in person or have any sense of permanency. Entropic forces soon swept over and erased it.

The following year, Heizer took his interlocking circle motif and expanded on it with his Primitive Dye Drawings. After carving circular forms into Coyote Dry Lake in the Mojave Desert, he scattered powdered dyes across the ground to produce colorful images. In this instance, the artist focused less on the drawn shape and more on how his painterly gesture would translate onto a large swath of earth, rooting these works more firmly in the tradition of painting than drawing. Working with primordial materials, Heizer used white lime powder and concentrated aniline to dye the earth within and beyond his shapes for an amorphous effect. Like his earlier desert drawings, the works were never intended to be permanent and eroded away rather quickly. As Heizer explained to Germano Celant in 1996: “Basically this is invisible art…It will survive only as a memory…I don’t like being burdened by objects…I make art that blows away, then it’s only a memory. I can go onto something else.”¹³

One year later, in 1970, Heizer executed a more methodical version of his circular motif in Circular Surface Planar Displacement Drawing at nearby Jean Dry Lake. He moved to this location at the direction of his friend Count Guido Roberto Deiro, a Las Vegas pilot and head of aviation for Howard Hughes, who leased the surface rights to the lake from the Bureau of Land Management for only $50.¹⁴ For this work, Heizer exchanged the bulky truck for a smaller, more nimble motorcycle, allowing for a more tightly controlled surface area onto which he could draw. With the support of professional racer Hank Lee, who operated the motorcycle, the duo traced a 900-by-500 foot work consisting of multiple drawings, including one almost identical in appearance to Tangential Circular Negative Line. The process was more precise this time around as the course was predetermined by strings connected to Lee’s motorcycle, anchoring the five central points of the linked shapes. This allowed Lee to drive mechanically around and around over the same tracks, embedding deep circles within the landscape. For Heizer, this gesture was intended purely for self-expression and discovery, an exploration of materiality and a connection to the natural world that usurped any interest in preservation or immortality. Once again, this work was overrun by natural forces and is no longer extant.
Heizer’s interlocking circular motif did not exist solely in the deserts of Nevada. Left image: In 1972, the artist recreated one of the motifs from Circular Surface Planar Displacement Drawing on a much smaller scale etched into the sidewalk on Bond Street in New York City just outside of the home of Sam Wagstaff, who owned the rights to the original drawing at Jean Dry Lake. In this instance, Heizer extends his gesture to a material that retained far more permanency, though it too has succumbed to the passage of time and since has been repaved. Right image: In 1970, Heizer executed another circular drawing outside Munich, a second iteration that was identical to Tangentical Circular Negative Line.

Around the same time, Heizer was interested in creating a lasting mark in the desert, the result being the monumental sculpture Double Negative (1969). Similarly located in the Nevada desert, this time on a mesa outside Overton, the project remains one of the artist’s most ambitious to date and is considered the first permanent earthwork. In order to acquire the land rights for the sculpture Heizer received funding from New York gallerist and 3M heiress Virginia Dwan, who one year later would finance Robert Smithson’s Spiral Jetty. Consisting of two incisions in the earth separated by a vast, eroded valley where the mesa falls away, the piece measures approximately 1,500 feet long, 30 feet wide, and 50 feet deep. In order to excise such immense trenches, 240,000 tons of rock were blown up using dynamite, with their remnants removed by bulldozer. In between the trenches lies the naturally eroded space between the artist’s interventions, which constitutes nearly one-third of the entire sculpture. This vast empty space takes on its own form that suggests a through line connecting each end of the valley. This implied volume is integral to the piece, as the artist notes, “Double Negative is the literal description of two incisions, but it has metaphysical implications, since a double negative is impossible. There is nothing and however it is still a sculpture.”¹⁵ Double Negative exemplifies the attitude towards materiality that Heizer preached to Germano Celant in 1996: “place is material, material is place.”¹⁶ To the artist, human intervention and natural surroundings are intimately intertwined—each site has not been positively or negatively affected but merely displaced and reimagined. Environmental changes over time are intrinsic to their existence.
Double Negative is approximately 70 miles northeast of Las Vegas. Located in Moapa Valley, along the eastern slopes of Mormon Mesa, the work is hidden within the landscape until stumbled upon. Ironically, step-by-step instructions are often required to discover the piece even with its monumental size.¹⁷ Viewers are encouraged to set foot in the trenches by traversing down-sloping 45-degree inclines. Once within, 90-degree walls barricade visitors in on two sides, drawing their attention to the massive valley and trench on the other side.
Contemporary reception of earthworks was mixed. Some critics praised the movement’s ingenuity and experimentalism. Carl Andre, in a 1968 interview for Avalanche, posited that land art may be “the end of easel painting. We may actually be seeing the end of not museum or gallery art, but the end of studio art.”¹⁸ Critic Lawrence Alloway praised the unique experience land art offered, writing, “Solitude characterises the Spiral Jetty and the Double Negative…Although the works are big, they are in no sense social. They are best experienced singly by spectators; only in that way can there be a proper acknowledgement of the sense of being alone that these works induce.”¹⁹ On the other hand detractors claimed that, despite their massive scale, many works remained inaccessible to the public as they were typically created in remote locations that required off-roading and hiking to encounter. Some critics went so far as to argue that the idea behind the earthwork was more significant than the sculpture itself. In his assessment of de-aestheticization, art historian Harold Rosenberg argued that earthworks were more dependent on publications than any other type of art due to this inaccessibility, as most of their audience exists through print rather than in person. According to Rosenberg, Heizer’s boulder-moving enterprises are “essentially art for the book—that is photographs with captions—since once the rock has come to rest, visual interest in it depends on the cameraman’s angle shots, his choice of distance, and the artist’s explanation of the project.”²⁰

This critique of inaccessibility was directed at several of Heizer’s works, as their reputations survived through myth rather than first-hand encounters. Take, for example, his infamous 1971 intervention in the lawn of the Detroit Institute of Art, titled Dragged Mass, which was commissioned by Sam Wagstaff, the museum’s curator and longtime Heizer supporter. Intended as a permanent installation, the piece was envisioned as an act of dragging a 30-ton slab of granite across the lawn of the museum over a period of three days, leaving behind a well-defined scar to memorialize the gesture. The outcome did not pan out as Wagstaff hoped: the stone dug into the lawn and became entrenched in a pit, upheaving the manicured grass and dirt underneath. The resulting destruction drew criticism from the museum’s board, who subsequently ordered for the stone to be immediately removed. Shortly after, the lawn was restored to its previously pristine condition, rendering any past trauma negligible. To Rosenberg’s point, if one was not present during the execution of Dragged Mass, they would not have been privy to what happened as no physical evidence remained. To this day, photography of the aftermath persists as the main source of information for nearly every viewer.

Heizer was keen to this phenomenon, using photography in his own way to not only document his land art, but concoct a narrative. For him, photography overcomes both temporal and performative aspects of land art’s creation. Because he insists that the only genuine way to experience his work was in person, Heizer has used photography to create a separate artwork in itself. These are not working drawings or studies, as they are created after the sculpture. For example, Circular Surface Planar Displacement Drawing / 90 degree Planar Rotary (1970) consists of 50 photographs collaged together of his corresponding earthwork, depicting the motorcycle’s tracks section-by-section in great detail. In order to create the work, the photographer had to strap a camera to a 24-foot scaffold, which was then pushed around 16 feet at a time for each shot. Presented in a circular pattern measuring 72 inches in diameter, the work echoes his gesture in the Nevada desert, taking on a visual presence beyond documentary photography. Even when Heizer is working outside of sculpture, he is still exploring the same vocabulary of shapes and forms, emphasizing how the same form can take on new meanings in different contexts.
Dragged Mass prompted an interest in bringing Heizer’s earthworks to institutions in a permanent form. In the late 1970s, heiress Philippa de Menil commissioned Heizer to recreate several of his desert drawings on the campus of her parents’ forthcoming museum The Menil Foundation, Houston. De Menil was the wife of Heizer’s German dealer, Heiner Friedrich. Several years earlier, in 1973, the couple cofounded the Dia Art Foundation with the art historian Helen Winkler. Three of Heizer’s Nine Nevada Depressions drawings, Dissipate (1968–1970/1994) [left], Isolated Mass/Circumflex (#2) (1968/1978) [center], and Rift (1968/1982) [right], were selected for the museum’s campus. In order to successfully reproduce these, the original designs had to be reinterpreted through a contemporary lens, using materials that would ensure permanency and changing the scale to coincide with the new topography. This time around, after Heizer executed the drawings in the museum lawn, weathering steel was inlaid to prevent erosion. While these gestures lose the sense of the artist’s hand that the originals had, they take on a new life, furthering the evolution of each shape and form.

In 2009, Heizer was approached for the first potential commission by the Air & Art Foundation, a Swiss organization dedicated to “develop[ing] contemporary art projects related to territory.”²¹ One of the foundation’s core tenets is to break down the hierarchy between viewers and institutions by placing public art in heavily trafficked areas, ones in which viewers may find themselves unexpectedly face-to-face with an artwork. Jean-Maurice Varone, a Swiss designer and project manager of the foundation, hoped to entice international artists to produce large-scale, in situ works that “interact with nature, the environment—a site—by relying on its history, its identity or other characteristics of the place.”²² Over the next few decades, Varone aspires to commission 13 sculptures throughout the Canton of Valais, one for each of its districts, to develop a traversable map of public art across the region. These projects are intended to be permanent alterations to the landscape, inviting an active exchange between viewers and their environment. They are intended to complement the fruitful output already instituted by Varone’s other public art program focused on Swiss artists, R&Art, which has already commissioned works by Felice Varini, Lang-Baumann, and Chapuisat Brothers, among others. In his initial pitch to Heizer, Varone noted that “he considered the mountains of Switzerland to be analogous to the American deserts in terms of scale and sublimity.”²³ Heizer was selected for the municipality of Bagnes, which up until 2011 was the largest in Switzerland, fitting for what would be Varone’s most ambitious and substantial commission to date.

When initially contacted by the foundation, Heizer pointed out that in 1970 he had intended to create a work related to his Vertical Displacement series in the Alps on the other side of the country from Valais, near Appenzell. Heizer conceptualized his Vertical Displacement works as large rock masses excised from cliff faces and lowered onto the cliff’s base, making a mark in the landscape while providing an entirely new context for existing material. None of these works have been executed. In 1970, Heizer travelled to Zurich with Bruno Bischofberger to search for potential rock formations that met their criteria. They got as far as photographing cliffs, receiving permission from the Swiss government to build, and bringing in engineers and construction workers. However, it turns out that the proposed rock formations did not possess the integrity to survive the excavation process.²⁴ Heizer described the process as “Mechanically, this work would have been dependent on gravity as the means to move materials. A small piece of rock would be broken out, it would fall away to the base, accumulate and become structure again. The evidence of its source would be directly above it.”²⁵ A series of works on paper illustrate this concept, depicting where Heizer imagined making cuts on the cliff face and how the ensuing lowering process would unfold.
Heizer’s work has always been produced in dialogue with where it is executed. In 1969, the German art dealer Heiner Friedrich invited Heizer to create a project for his gallery, the artist’s first project in Europe. The only object Heizer placed in the gallery was a set of directions leading to a 16-foot deep, approximately 100 meters in diameter hole dug into the soil of a Munich suburb. In a 1982 interview, he recounted, “The point of the Munich Depression at the time was that it could be built anywhere in the natural world. In Munich I was surprised to be working with beautiful gravels…By exposing its materials this sculpture became an analysis of its place.”²⁶ While standing in the center of the work, Heizer realized that he had completely erased the landscape in Munich, defining a section of land that seemed entirely foreign to not only Europe but all of Earth.²⁷ Just over a month after its execution, an expansion in urban development led to its bulldozing.
A map of the surrounding area shows the four proposed sites with the Mauvoisin Dam in the background. While site "C" was initially selected, the sculpture was ultimately constructed on site "B."
As discussions for the realization of Tangential Circular Negative Line progressed, certain concessions and limitations had to be put in place, especially since the work would be the largest recreated Heizer drawing to date. Originally, the artist was optioned four potential sites by the foundation. Regardless of the chosen location, another monumental sculptural presence—the concrete Mauvoisin Dam—would overlook the drawing. At 250 meters (820 feet) high the dam is the eighth tallest in the world, providing not only hydroelectric power generation but also flood prevention and sediment control, both of which would allow Heizer’s sculpture to exist in situ without any major natural interferences. Though he received photographs and maps of each site, Heizer was not capable of travelling to Switzerland due to health issues. In his place, he sent Peter Freeman for an in-person evaluation.

After selecting site “C,” Heizer was informed that it was no longer viable as it was located within a “red zone,” presenting an active danger of falling rocks. A proposed solution was to move the work closer to the dam. This prompted a lengthy exchange, during which the artist emphasized that he did not wish for his drawing to be overshadowed by the sculptural presence of the dam. Site “B,” which sits 280 meters (918 feet) further away from the dam than site “C,” was chosen as a compromise, allowing the two structures to coexist. In order to make the new location function, the sculpture had to be scaled down slightly and a dirt road had to be relocated further south. Another complication arose when the budget was confirmed, as the initial quote for the steel’s fabrication and shipping exceeded expectations. For much of his career, Heizer used a company in Los Angeles known for their precision and efficiency to produce materials for his works. Just as Heizer set out to create a uniquely American form of art, he likewise insisted that his artworks should only be fabricated in America.²⁸ However, Varone argued that local manufacturing was the only way to stay within the Swiss government’s budget. After several rounds of negotiations, Heizer accepted Varone’s proposal knowing that Swiss engineering would meet his high standards.
One of the smaller circles of Tangential Circular Negative Line being manufactured by the Swiss firm Zwahlen & Mayr.
Construction for the Swiss version of Tangential Circular Negative Line began in 2012, 44 years after its conception in Mirage Dry Lake. It took the local firm Zwahlen & Mayr three months, from March to May, to fabricate the steel walls. The finished product constitutes 16 mathematically precise sections of Corten steel—eight for the large circle and four for each small circle—all together amassing 27 tons in weight. At the same time, a crew began preparing the agreed upon site. To emphasize the sculpture’s negative space, they created a unified plane between 1,840 and 1,841 meters (6,036 to 6,039 feet) above sea level with strict instructions that the ground must remain absolutely flat within its perimeter at all times. Because it was formerly a pasture, thousands of square feet of native soils had to be displaced to achieve this uniformity. Once this was accomplished, they poured gravel sump into the recessed earth to prime a base for the bricks underneath the Corten steel. In two short months, the site was finalized and installation began.

The installation process of Tangential Circular Negative Line proved to be as much of a spectacle as the finished work. Transporting the Corten steel pieces through the precariously narrow streets and one-way bridges of the Alps acted as a kind of procession, a feat perhaps as evocative and theatrical as the sculpture itself. As William L. Fox quips, “photographs of trucks carrying the heavy steel arcs over the one-lane bridge could serve as an illustrated lesson in precision driving.”²⁹ This performative aspect is not uncommon in Heizer’s work; after all, he did detonate 240,000 pounds of rock to create Double Negative. Once the trucks reached the site, each piece of the steel foundation was laid onto the bricks one-by-one, sitting approximately two feet below ground level. Fill gravel was then placed around the sculpture in order to materialize the negative space of the earthwork, illuminating the work’s appearance as a “drawing” in the earth.
After three years of careful planning and organizing, Tangential Circular Negative Line opened to the public on 18 August 2012. Reception was positive: Sibylle Omlin, the director of the École cantonale d’art du Valais, referred to it affectionately as a “Swiss Heizer,” likening the work to modernist Swiss sculpture.³⁰ Art historian Benôit Antille deemed the sculpture a “quotation or ‘reenactment’” of his earlier desert drawings.³¹ The Air & Art Foundation was similarly pleased, writing that the three-ringed work “found its home in the heart of the Swiss Alps…surrounded by snow-covered peaks.”³² Heizer himself acknowledged that the work “held its own” against the majesty of the Alps.³³
Since Tangential Circular Negative Line was realized five decades after its conception, and in a wildly different context, it must be considered on its own terms. Now situated in the Swiss Alps, the sculpture recalls the idea of the sublime, which has historically been deeply connected to the region through art, philosophy, and literature. On a more practical level, due to its high elevation and limited passages, the sculpture is difficult to travel to and inaccessible for a good part of the year, as the pass frequently becomes snowed in during winter. Perhaps neither of these ideas align with Heizer’s initial conception of the work. And yet, the final product is indisputably a Heizer, as it returns to the basic idea of drawing on a landscape. The sculpture thoughtfully considers its surrounding landscape and responds accordingly, inviting viewers to reassess how, as the artist proclaims, “Man will never create anything really large in relation to the world.” And when taken in holistically, with the sublime Swiss landscape behind it, the installation feels like more than just art—it also delivers a religious experience, just as Heizer envisioned.
