Concept

BEYOND SILICON:

FROM HIGH-TECH DIGITISATION TO  HIGH-END CARBONISATION

"To detach a fresco from its space is to initiate a radical ontological liberation. It is the act of decoupling the monumental essence from every structural constraint, transforming its tectonic permanence into a fluid, planetary environment. This does not merely constitute a displacement; it is a phenomenological transduction: a radical shift from silicon high-tech to carbon high-tech."

                                                                                                                                   

If the hegemony of the eye isolates the subject by reducing human existence to a fleeting gaze, the imperative duty of contemporary art is to reinstate essence through structure.

Generative algorithms, an unrelenting stream of images, and the planar digital archives of display screens have severed human memory from its physical substrate. We no longer perceive monumental art as a resonant physical mass that demands proximity; instead, we consume it as a superficial visual regime—ephemeral pixels parsed through the detached, distancing gaze of an ocularcentric dogma.

​

The critical inquiry emerges precisely at this threshold: Can we liberate monumental painting from the tyranny of the retina? Furthermore, is it possible to transform the digital from an optical trap into an authentic, tactile territory?

​

The Dislocation: From the Wall to Point Clouds and from Digital Matrix to Tactile Pixels

​

This exact rupture is what Tactile Commons seeks to bridge. Rather than capitulating to the passive reproduction of cultural icons on flat monitors or virtual-reality headsets—technologies that merely exacerbate sensory isolation—the project initiates a radical physicalisation of the digital.

Through high-resolution 3D terrestrial scanning, monumental fresco compositions are extracted from their tectonic architectural skins not as photographic records, but as spatial mathematical formulations: dense clouds of Cartesian points (point clouds). Instead of remaining confined within the sterile, disembodied realm of digital storage, these data sets are driven through a fundamental material transition:

  • The digital point cloud is materialised into physical, topographical pixels.

  • Pigment, brushstroke dynamics, and monumental composition cease to be colours observed at a safe, voyeuristic distance; they become micro-altitudinal gradations, tactile pulses, and somatic resonances engineered to be embraced and deciphered by the human hand.

​

The circular diameter of 1.20 meters characterizing the Tactile Commons panels corresponds strictly to the ergonomic span of human embrace. At this scale, the visitor no longer stands back to consume a panoramic image; the body enters an unmediated tactile dialogue with the material plane. The hand itself turns into a magnet, conducting energy through the entire somatic architecture.

​

A Cybernetic Biofeedback Loop

​

To dismantle ocularcentrism, visual temptation must not merely be moderated—it must be extinguished. The sighted visitor and the visitor with visual impairments cross the threshold into the identical perceptual condition. The visual privilege that has governed Western art reception since the Renaissance is neutralized in an instant.

Stripped of retinal dominance, the body activates a closed bio-haptic feedback loop. The palpation of the surface, the resistance of material textures, the deceleration of the pulse under the demand for deep concentration, and the kinaesthetic awareness of bodily posture synchronise dynamically.

​

Cognitive Prosthetics and Acoustic Confirmation: Navigating across relief pathways on the floor, localised directional soundscapes mapped to spatial coordinates, and tactile magnetic anchors do not function as passive navigational aids; they operate as cognitive prosthetics. Each touch delivers an afferent signal to the brain, the auditory feedback confirms the spatial coordinate, and the magnetic node realigns orientation. The tactile visitor ceases to be an external observer, attuning biologically to the work through continuous, embodied self-regulation.

​

Touch as Synthetic Vision: Deciphering the composition becomes a slow, rhythmic choreography. Fingertips trace a gesture, the ear captures an acoustic spatial harmonic, and the palm defines the boundary of a figure. The emergent mental image is not an ephemeral screen capture but a grounded, multisensory synthesis.

​

A Technoetic, Decentralised & Non-Dual Condition

​

Responding directly to contemporary sensory alienation, Tactile Commons demonstrates that an artistic and spatial design practice emancipated from retinal hegemony is not a utopian aspiration but a viable, urgent imperative.

When the visual spectacle is arrested, the isolation of the eye gives way to the communion of touch and the deep biological engagement of the body. Art escapes museum vitrines and/or algorithmic feeds, evolving into an open, accessible commons—a shared, distributed multisensory ecosystem.

​

This emergent ecosystem of Tactile Commons is neither digital nor analogue nor hybrid. It is a technoetic, non-dual ontological state—an indivisible field where the algorithm, tactile resonance, and human consciousness coexist as an unmediated commons.

The Process

THE PROCESS

Tactile Commons strips away art and technology from systemic noise, resulting in universally accessible cultural assets. It transmutes monumental art frescoes into pure magnetic fields while reconstituting the artwork's forms and colours into elements of resonance. Sighted and non-sighted participants interact as tactile viewers, breaking the cybernetic loop to engage in a collective, inclusive experience.

 


FROM HIGH-TECH TO LOW-TECH

The Transition: Deconstructing high-end scanning into a low-tech process. Information from the produced point cloud is shifted to algorithmic dithering, then reduced to a raw bitstream.

​The Goal: Focusing on media archaeology, the process reaches the primal digital form of the bit and strips the work of its visual representation to reveal its pure structure.
 

FROM OCULARCENTRISM TO RESONANCE 

The Rationale: The artwork transcends the conventional methods and aesthetics that regulate art. Working at the edge of artisanal, the process strips art of aesthetic intrusion.

​The Act: Through a 'blind' process, the artist recreates the fresco without visual confirmation. Using an artisanal approach to the raw bitstream, the artist tessellates thousands of tactile pixels and recreates the fresco.
 

FROM BLACK BOX TO MAGNETIC FIELDS

​The Rationale: Technology here is a humble energy translator. It ceases to be a binary scheme and becomes invisible energy emitted into space.

The Act: Translation of forms and colours of the fresco into a flux of magnetic fields.

The Mechanism: Through tracing, magnetism stimulates the nervous system, allowing the brain to apprehend the fresco as a direct neural impulse. Technology returns to its essence: the flow of energy.

​

FROM HIGH COGNITION TO NEUROPERCEPTION

The Experience: This infrastructure allows the participant to bypass high cognition—the analytical way we process knowledge—and surrender to an immediate interaction.

The Action: By tracing the surface, interaction becomes a kinetic event—a neural dialogue that emancipates both the medium and the content from the weight of traditional hierarchies and inherited biases. 

​

VISITOR'S EXPERIENCE

​

The project moves beyond posthumanism, shifting from the mere technological extension of the body toward the participant's direct connection with the artwork's flux. In this condition, technology serves as a bridge, not a bypass. By tracing the surface, sighted and non-sighted participants close the cybernetic loop, experiencing an embodied dialogue through kinetic response. In this decentralised environment, participants do not merely exist within the system but operate as its shifting centre, breaking the circuit of control. This democratisation of the experience transforms both artwork and technology into an inclusive, shared reality—a space where optical boundaries dissolve, filling the void with structural resonance and unmediated neural presence.

The Prototype

THE PROTOTYPE
ανοικτος κωδικας

The monumental fresco ensemble by Iannis Karoussos [1] in the Cathedral of Saint Andrew in Patras stands as one of the paramount achievements of contemporary Orthodox monumental art, destined to shape the modern cultural heritage of future generations. Having already established itself as a vital point of reference in academic research and contemporary artistic expression, it unquestionably constitutes a core pillar of Greece’s cultural legacy. The work reveals both the historical continuity and the vanguard nature of monumental art, ensuring the enduring vitality of Greek cultural heritage over time.

​

The fresco cycle spans an extensive surface of 2,600 m². The key sections that exemplify the innovative character of the artist’s oeuvre include:

​

  • The Iconographic Program of the Dome (1989–1992): A masterly artistic statement spanning a total surface of 997 m² (including the pendentives) at a soaring height of 40.50 metres. Along the base ring of the dome, the Creation of the World—inspired by the mosaics of the Cappella Palatina in Sicily and Saint Mark’s Basilica in Venice—bears witness to the artist’s transformative vision at the forefront of modern Orthodox monumental art.

​​​​​​​​​​​​​​​​​​​​​

  • The Platytera in the Central Eastern Apse (Late 1985): The most defining composition marking the imprint of a major artist. The central apse encompasses an area of 220 m², with the depiction of the Platytera spanning a width of 20 metres. In this groundbreaking composition, the Virgin Mary is depicted embracing the modern city of Patras, departing from the conventional representation of an ancient Byzantine cityscape typically found in Orthodox iconographic tradition. The objective was to foster a seamless dialogue between the fresco and the parishioners. Despite initial hesitations about this groundbreaking depiction, the faithful soon embraced it, feeling that the Virgin Mary was literally enfolding their everyday lives. The Platytera of Saint Andrew in Patras has already served as a reference model, most notably in the new Saint Nicholas Church at Ground Zero in New York, designed by architect Santiago Calatrava.

 

  • The starry skies adorning the small domes of the south aisle forge an exceptional visual dialogue, bridging the Roman mosaics of the Mausoleum of Galla Placidia in Ravenna with the Starry Night of Vincent van Gogh.

​

​

​ [1] Iannis Karoussos (1937–2013), often characterised as the painter of monumental surfaces, was the pioneer of contemporary Orthodox monumental art. His seminal fresco ensembles—the Church of Saint Panteleimon on Acharnon Street in Athens, the Cathedral of Saint Andrew in Patras, the Rotunda of the Church of San Teodoro on the Palatine Hill in Rome, and the exquisite narrative cycles in the narthex of the Mega Spilaio Monastery in Kalavryta—are widely regarded as benchmark masterworks of modern Orthodox monumental painting.​​​​​​​​​​​​​​​​​​​​​

From Wall to Field:

The New Spatiality of Monumental Painting

Katerina Koskina

Katerina Karoussos belongs to the fourth generation of an artistic family with a long-standing, active dedication to Orthodox monumental art. She is the first woman in this extensive family lineage, particularly in the monumental iconography of the interior architecture of Orthodox churches in Greece. The history of the Karousos family can be read as an ongoing, successive encounter between Orthodox pictorial tradition and the prevailing artistic and aesthetic currents of their respective eras.

As early as the mid-18th century, Efstathios Karoussos¹, during his artistic activity in present-day Italy (Naples, Trieste, Venice), had incorporated Baroque elements into the Orthodox painting tradition. Dionysios Karoussos engaged in dialogue with the Nazarene movement². Ιannis Karoussos, father of Katerina, approached modernism in his visual art³. Consequently, examining their trajectory, we observe that it does not represent a linear transmission of an immutable visual idiom but rather an ongoing process of combining and creating a dialogue between the Orthodox tradition and the plastic achievements of each era, leading to a renewal of the 'script' and a reinterpretation of this art through a contemporary perspective and perception.

 Each generation of the Karousos family seems to affirm that tradition remains alive precisely because of its ability to engage in dialogue with the present, regarded as an integral part of art without relinquishing its liturgical character. Orthodox monumental art—often enveloping the entire surface of church interior walls and vaults—is therefore defined by them not as a closed, immutable system of forms, but as a living language capable of traversing time, converging with diverse aesthetics, and incorporating new techniques and conceptions of religious iconography.

Within this familial succession, Katerina Karoussos marks the next step—one that could well be characterised as a watershed: she brings Orthodox monumental art into the 21st century not by repudiating tradition, but by exploring the possibilities afforded by contemporary digital media. Her visual practice unfolds along the threshold between image, architecture, and space. Specifically, she investigates how Christian Orthodox fresco painting can be emancipated from the specific site and material conditions that traditionally define it, employing the tools of today without compromising its spiritual and ethical essence.

Her position in this lineage is especially significant. While Efstathios, Dionysos, and Iannis Karousos responded to the artistic movements of their eras through tools and techniques that had remained constant for centuries, Katerina is called upon to confront an even more radical transformation: a contemporary landscape where the image is no longer confined to a two-dimensional surface or to conventional styles and media.

Digital technology, augmented reality, and new forms of spatial and interactive experience radically alter the landscape and the ways in which an image is produced, perceived, and extended into space. It is at this juncture that family tradition converges with, yet simultaneously diverges from, Karousou’s personal visual exploration.

The gesture of detachment is, therefore, far more than a mere shift in presentation. It constitutes a process of deconstructing the image itself into its constituent elements. Form, line, colour, light, surface, and void acquire a newfound autonomy, as they can now unfold beyond the boundaries of their original architectural context. The image is no longer a static object upon a wall but an open structure capable of moving, transforming, and forging new relationships with both space and the viewer. The materiality of the works, though fluid and visually permeable, contributes decisively to this dialogue. Rather than imposing a sharp boundary between image and space, it evokes the sensation of a continuous transition.

The gaze does not "collide" and halt upon the two-dimensional surface; rather, it appears to permeate it. The image thus becomes less compact and more of a field—a Kampos (background field), according to the terminology of Orthodox iconographic tradition—and consequently less of an object and more of a process.

The transition from the two-dimensional surface to spatial expansion inevitably gives rise to a different relationship with the viewer. Where traditional iconography primarily orchestrates a visual encounter, Karoussos’s works activate an expansive, multisensory experience.

The transition from the two-dimensional surface to spatial expansion inevitably gives rise to a different relationship with the viewer. Where traditional iconography primarily orchestrates a visual encounter, Karoussos’s works activate an expansive, multisensory experience.

Touch, sound, movement, spatial perception, and immersive experience can function complementarily to sight, transforming the work from an ob-ject of visual contemplation into an open environment of experience.

Augmented reality takes on a distinct significance within this context. It does not merely serve as an added technological layer atop the image but as a medium that allows the image to gain a second, immaterial dimension. The physical and the digital coexist, while the sacred scene can continue to exist beyond the boundaries of the physical surface. The image may be at times material and at others immaterial, at times fixed and at others mutable—remaining perpetually in a state of becoming.

In the installation Tactile Commons, to be presented this coming October at the Benizelos Mansion in Plaka, this becomes unmistakably clear. This is because, while one might expect the image to transition from a two-dimensional surface into space, an inverse trajectory is pursued instead. Here, accommodating the needs of individuals with low or no vision, the pixels of the digital photographic image regain their materiality, presented as a tactile relief of tesserae and voids. Thus, endowed with a tangible "body", they open up for contemplation as a tactile experience.

Whichever path she pursues, Katerina Karoussos does not treat tradition as a static past to be merely conserved. She approaches it as an active, dynamic legacy that acquires meaning through its capacity to transform. A defining role in this continuous process of evolution is played by the Karoussos Archives, which she established and continues to expand. Operating not as a static repository of documentation but as a vibrant hub for research, dialogue, and innovation, the Archives fosters the stewardship and valorisation of this multi-generational history and monumental heritage.

Through cutting-edge practices, it transforms archival material into a living experience, offering a body of work that is collective and deeply rooted, yet simultaneously evolving and interactive, open to research, and accessible to all.

The thread connecting these four generations lies not in the repetition of a predetermined technique or form, but precisely in the audacity of each generation within the same family to seek its own language and medium within its own world.

From Baroque to the Nazarenes, from Modernism to the digital and interactive imagery of the 21st century, the Orthodox monumental painting of the Karousos family narrates a history of continuous evolution. This gradual shift from generation to generation assumes a new dimension: the image reflects its time, its broader context, its role, and its means of realization. The transmission of the same spiritual message is achieved through the tools, expressive idioms, and modes of spatial engagement afforded by each era of creation. In reality, it does not simply trace the path of its origins.

It has moved from the wall into space, from solid surface to fluid, permeable materiality, and from the physical realm into the digital. The legacy remains vital not merely because it changes, but because it can transform its medium, form, and reception while fiercely preserving its essential core.

The art of Katerina Karoussos emerges from the intersection of family history and artistic lineage with the contemporary era. She does not renounce the sacred character or the spiritual Word (Logos) of Orthodox art. Moving beyond the two-dimensional surface into space, or employing new technologies, does not signify a departure from conveying the sacred message. She does not abandon Orthodox tradition; rather, she expands its frontiers, equipping it with novel possibilities for reading and perception. Through this expansion, Orthodox monumental art endures—not as a static representation, but as a contemporary, experiential, and spiritual presence.

Digital Translation

DIGITAL TRANSLATION

The central objective of the digital documentation was to preserve and safeguard the monumental ensemble; despite its contemporary date (1995–2013), deterioration caused by environmental conditions made digital recording imperative. Concurrently, through emerging technologies such as virtual and augmented reality, we developed new, immersive modes for presenting the fresco work.

Crucially, this endeavour enabled us to leverage digital documentation to create experiential, inclusive engagements. This project was funded by the Hellenic Ministry of Culture and executed in 2024 by BeeSTEAM.

The digital documentation workflow encompassed the following stages, chosen for their ability to provide the high precision and fidelity essential for capturing the cathedral's frescoes' unique characteristics.

A mirrorless camera was selected for its high resolution and flexibility at challenging angles, while aluminum and carbon-fibre extensions facilitated stable capture from elevated heights, ensuring the requisite accuracy. Remote camera operation further guaranteed maximum stability during shooting. In addition, state-of-the-art point cloud processing software ensured the precision of the generated 3D models, rendering them fully suitable for future implementation across diverse applications. 

The spatial accuracies achieved are 7 mm for the dome and the eastern niche, and 1.5 mm for the small dome. Triangulation methods applied to the point clouds generated three-dimensional models enhanced with detailed photorealistic textures. The resulting point clouds comprise:

  • Dome: 26,880,259 points

  • Eastern niche: 25,047,631 points

  • Small Dome: 12,487,273 points

The point cloud datasets encapsulate all data regarding the current state of preservation of the artworks and were utilised to construct high-precision 3D models. Through specific processing methodologies, insights into the condition of the works can be deduced, accurately recording the geometric and chromatic properties of the frescoes. These models lend themselves to a wide array of applications, including condition documentation, conservation support, and integration into interactive digital platforms.

Correspondingly, the surface meshes of the 3D models consist of:

  • Dome: 2,684,665 triangular facets

  • Eastern niche: 1,329,352 triangular facets

  • Small Dome: 1,802,030 triangular facets
