For Pierre Jardin, it was truly a pleasure and privilege to be invited by Julian Charrière to write a text for his exhibition A Stone Dream of You at Sies + Höke gallery in Düsseldorf April 4th – May 3rd, 2025. This post is the second reflection on Charrière’s work, following on Volcanic Erratics.
Magmatic Möbius Strips: After the Smoke Cradle

Pierre Jardin is practically pressing his nose to the glass in the middle of a six-foot (2m) artwork hanging on the wall in Sies + Höke gallery. After reading that it was “printed with pigments derived from obsidian, sulfur, volcanic ash, and crushed lava stone,” Jardin was especially excited to encounter this and other works in Julian Charrière’s series After the Smoke Cradle (2025).

Sidling up to the fumarole at the base of a lava flow in the photolithograph, he is hoping to simulate breathing in vapors from a volcanic vent. The sophisticated Düsseldorf crowd at this opening event must wonder what the crazy Californian has been smoking, but this is actually Jardin’s first attempt to inhale a foreign substance this evening.
Jardin’s desire to respire the smoking Earth represents a further iteration of his “geologic aspirations,” a series of respiratory experiments entitled Breathing with Mountains. There, drawing on Daoist thought, Jardin conceived cycles of orogeny and erosion as the Earth breathing. Francois Juillien summarizes this view succinctly: “Breath-energy circulates without interruption through the landscape’s lines of force…. Following the alternations proper to it, rising and falling, soaring upward or sitting down, the mountain brings about the great respiration of the world” (Jullien, The Great Image Has No Form, p. 136.) Here, the prospect of inhaling Charrière’s Smoke Cradle works intrigues Jardin because, more than breathing with mountains (and the Earth), doing so would mean breathing in the Earth—not just the Earth per se but its hidden interiority, its inner secrets.
After the Smoke Cradle, images formed from tephra, “does not depict volcanic landscapes—it embeds them.” A comparable aesthetic of directly registering rather than representing landscapes informs Chinese scroll paintings, which transcribe the breath-energy “spirit” of mountains and landscapes into ink. Like these works, Charrière’s images evoke the vastness of mountain ranges by letting them recede into nebulous forms dissolving in the distance.

As Jardin approaches these images, their grainy quality dissolves further; as the splotchy texture becomes milky, it feels like being immersed in sulfurous clouds and molten rock. Charrière informed Pierre that the snowy wash of the images, a kind of surface veneer, was achieved by applying a layer of obsidian ash. The resulting world is an existential nether zone; the image below reminded Jardin of Samuel Beckett’s stage setting for Waiting for Godot:: “A Country Road. A Tree. Evening.”

No longer a spectator outside looking in, Jardin is saturated by or swimming in the image. This perspectival flip is like crossing a fold; Jardin feels a bit like Alice passing through the looking-glass. But while Carroll’s world reverses left and right like a mirror, Jardin-Charrière’s world turns inside out like a Möbius strip. Going inside these volcanic works, Jardin enters the Earth where it turns itself inside out, spilling its fiery guts and breath onto the surface, remolding itself in the process.
Projecting himself into Charrière’s volcanic cones, Jardin is not Carroll’s Alice but Jules Verne’s Axel, following his uncle Otto Lidenbrock and their guide Hans into Snæfellsjökull in Journey to the Center of the Earth. As the book’s “fantastic voyage” illustrates, volcanoes are both ways into the Earth’s interior and ways out (they are spewed back to the surface in an eruption of Stromboli).

The exhibition didactic declares that the Smoke Cradle series “fold geological time into their very surface.” Jardin reads the works as geologic time-folds, surfaces where the inside becomes the outside and the outside enfolds an emergent inside. The Litli-Hrutur landscapes in particular display a dynamic, non-Euclidean topology, crumpling surfaces with rising, hollowed-out cones along which oozing lava flows descend and from which sulfurous vapors steam up in clouds.
This topology of the outside as a fold of the inside is replicated in one of the most distinctive elements of these works, their frames. Rather than an external decorative element added later, the frames are carved from basalt boulders which, like the pigments in the photolithographs, were collected from the sites depicted in the images.



Confounded and captivated by this confusion of container and contained, Jardin found himself peering closely at individual boulders shown in the images, and wondering whether they might also have been used to form the frame.


If so, the same rock would appear twice, once in an image printed with pigments of crushed stone, and again as ‘itself,’ in the frame ‘outside’ the image…. Trying to wrap his mind around this thought, Jardin gets in his own head and ends up beside himself.
Subsequently, Jardin lost himself in sustained contemplation of folds between frames and images, taking several photographs to record his observations. The visual rhyming of white-spotted, mottled textures establishes a continuity or consistency that implicitly identifies or analogizes the frame with the image.



Simultaneously, the frames crystallize the flows and fumes in two senses. Visually, their cleanly carved surfaces bring the basalt into focal clarity, suggesting that they serve as rock samples of the materials in the murky images. Geologically, magma (seen in the image) cools and crystallizes into basalt (the frame).

The Smoke Cradle compositions conjure underworldly worlds breathed into being by an expiring Earth. They are haunting deep-time portals, portraits of the Earth’s ceaseless creative-destruction of itself. Like the rock cycle and plate tectonics, volcanos record how our porous planet forms-deforms itself by turning itself inside-out (e.g., eruption) and outside-in (e.g., subduction). Inside the Earth, convection currents of magma—heating and rising, cooling and sinking—dissipate heat from the mantle, driving continental drift and seafloor spreading. Solid rock in the mantle is melted and works its way upward through lava tubes, magma dikes, and venting systems, changing in composition through crystal fractionation.
Traces of the deep inside of the Earth reach the surface in magmas that carry pieces of the mantle, called mantle xenoliths. Xenoliths, “foreign rocks,” are pieces of rock trapped in an igneous rock during the magma’s ascent. In geologic terms, mantle xenoliths form at “Moho depths,” a reference to the Mohorovičić discontinuity that marks the boundary between Earth’s crust and the underlying mantle at an average depth of about 35 km (22 miles) beneath continents. These rocks thus provide a direct means of studying the composition and history of the earth’s mantle underneath a given landscape.
On his trip to the Mojave Desert with Brian Rajski days before departing for Düsseldorf, Pierre Jardin hiked a 2.1 million-year-old cinder cone in the Dish Hill Complex and collected mantle xenoliths with mainly green peridotite crystals. This excursion proved to be prescient preparation for encountering the Smoke Cradle works and thinking about volcanic eruptions and Earth time.

The Mojave xenoliths have been the subject of extensive geologic studies and interpreted as evidence that material buried in the ancient continental mantle escaped tectonic erosion by low-angle subduction of the Farallon plate beneath North America during the Laramide orogeny 88-55 million years ago. Mantle xenoliths are folds where the ancient, deep interior of the Earth erupts to its external surface. Jardin packed one of the xenoliths to give Charrière, whose studio showcases stones from around the world.
The Smoke Cradle works and mantle xenoliths map geologic time as a Möbius strip. The rock cycle and plate tectonics ensure that, among all known planets, the Earth is uniquely dynamic. The Earth is not a ‘ground’ but an ungrounding. Its solid, brittle continental surface is always drifting and shifting; its seafloor is always spreading and subducting. The Möbius strip expresses the ways in which geologic time unfolds in cycles and remixes itself by turning itself inside out and outside in.

This conceptual time image more aptly diagrams terrestrial temporality than the linear timeline marked off by the geologic timescale or the familiar figure of ‘deep time’ as successively buried strata. The Möbius strip also closes the loop, as it were, on one of the most compelling visualizations of Earth history, “The Geological Time Spiral. A Path to the Past,” a poster designed by Joseph Graham, William Newman, and John Stacy for the United States Geologic Survey in 1975.
This celebrated historical infographic effectively charts key events in post-Cambrian Earth history and illustrates the evolution and emergence of plants and animals preserved in the fossil record. But the upward moving spiral doesn’t communicate the burial of what surfaces or the evolutionary reboot marked by extinction events. One could imagine the spiral connecting back on itself at such times; spatially, this would induce a Möbius topology or, perhaps add a dimension and transform the Möbius strip into a Klein bottle.
The Möbius strip allows one to think of time having no inside or outside. It also metamorphoses the linear flow of time into a continual twisting on itself. The crumpled topology of the Smoke Cradle eruptions and lava flows resonates with this conceptualization of time. This topology is mirrored in volcanic rheology, or flow behavior. In his exhibition text “A Dreamology of Geology,” Pierre Jardin underscored a common rheology: “Both the rock cycle and dream cycle are driven by differential improvisational exchange in slurries of pent-up materials subjected to stress and strain vented by distilling and crystallizing into residual elements as they surface.”

Rajski, in his Mojave lava flow writings, encapsulates the concept of time embodied in the rhythms and viscosity of magmatic rheology: “The lava that created these flows can be treated as Bingham plastic fluids that ‘act as a rigid body until a certain force is applied.’ … Rather than the cliché of ‘time is a river,’ these lava fields therefore metaphorically offer a complex image of the passing of a time that is viscously always being held back by the past and energetically thrusting forward past its limits into the future.”
Geologic time is a sticky nonlinear process that blocks up and overflows itself as it cools and crystallizes. Geologic time is both/and // neither/nor a creator or destroyer: geophysical processes do not produce or demolish matter but remix and redistribute it. The Earth is a self-absorbed involvement with itself that evolves and devolves as it melts and cools, slip-sliding away and solidifying at the same time all the time. In the folded time of geology, the “present” literally carries the past and harbors the future within itself.

After the Smoke Cradle evokes the folding nature of geologic time, the externalizing of internal processes. The works function as a fold in time, an episode or eruption event that simultaneously erases an existing landscape and composes a new one. The volcanic fold is a temporal caesura, both an end (break from the past) and a beginning (opening to a future). Composed from / compositions of volcanoes, the lithophotographs stage a phenomenological encounter with telluric force and terrestrial time. Resonant with chthonic sensations and images, they bring the buried unconscious oneiric world we yet carry within us to the surface, while conversely drawing us into the depths of the Earth. In a moment after the end of the world and before the birth of a new Earth, we dimly dream, re-collect, re-assemble within ourselves, the immemorial time of stones.
