Exhibition 'Gold over black' (2025)
Based on three years of travels and treks through different biomes in Brazil and Canada, the exhibition ‘gold on black’ brings together artistic photographs of nature, installations, performances, maps, music, and video to reimagine the art gallery as a sensory forest. Conceived as an immersive experience, the show invites visitors to investigate mysteries, constructing their own meanings for the works from a dark and synesthetic environment. Questioning how each person's paths add different values to nature, guests are confronted with their own fantasies in search of a lost ‘El Dorado’ or ‘Pindorama’, hypothetical and utopian places that are built as the spinning top of life turns.

Mathias Reis's playful journey by Paulo Cheida Sans
I have followed Mathias' artistic trajectory since the beginning of his undergraduate studies in Visual Arts in 2012. I remember his participation in the Brazilian Nanofilm Festival in Atibaia in 2014, and his performance-denunciation video for the 8th Biennial of the Bizarre, exhibited in Atibaia and Lima (Peru) in 2019. Furthermore, I highlight his diverse ideas and works in varied creative possibilities. I had already seen much of the artist's work and was always positively surprised. I knew of his multimedia abilities, his musical talent, his refined education, and his persistence in dedicating his personal pursuit to Art and Nature. For Mathias, Art and Nature merge in an expressive symbiosis of conduct as a person. Yes, artist and person complement each other. It's not enough to enter the studio and feel like an artist. But, when walking, dressing, and eating, the artist-person is one, the same, who appreciates Art and Nature. Mathias is the work. To illustrate this thought, I bring to light what the renowned artist and ecological activist Franz Krajberg (1921 – 2017) said: "Aesthetics are not enough for me. The work must be able to echo and reverberate the cry I carry in my chest." Mathias, in his calm and serene way, cries out artistically. He captures the beauty of nature like a magical painting in his photographs. Just as he captures the images of performances as one extracts the mystery and magic from the darkness of each scene portrayed.
At AT AL 609, Mathias Reis's exhibition "Gold on Black" transforms the gallery into a sensory forest, bringing together photographs, installations, performances, maps, sound, and video. The interactive experience is activated by the visitor, who, by spinning a top as in a treasure hunt, assumes the role of participant. Equipped with a flashlight that projects golden lights, he walks through the exhibition rooms, uncovering new visual interactions that provide a playful and immersive journey. It is a unique encounter with Nature, revealed through the artist's gaze. The exhibition "Gold on Black" is much more than an exhibition; it is a work of art in its entirety. Mathias creates a work with his talent for exhibition design, sound, and multimedia, and as an artist, he has created the allure of his and our "truth": we are Nature. The playful and refined journey that Mathias proposes is a look at what we have and are in our own world. The artist uses subterfuges of rare sensitivity to propose a visual, auditory, and sensory journey. This reminds me of José Saramago (1922 – 2010), and thus, paraphrasing this writer, poet, and Nobel Prize winner for Literature (1998), I would say that Mathias knows that: "what gives true meaning to the encounter is the search, and it is necessary to walk a long way to reach what is near."

Artist statement
The exhibition stems from my research on creative processes in relation to the environment and landscape. For the past ten years, I have dedicated myself to creating works of art in which nature plays a fundamental role in their conception and, in various ways, a leading role. This perspective begins by removing my personal life, or my self-conception, from the center of attention to focus on the direct sensory relationship with other life forms and geophysical forces, perceiving a plurality of vital expressions that become raw material for artistic creation and gradually modify my way of seeing and being in the world.
I largely avoid romanticizing nature because, while life is in constant flux, conflict is also constant, as is grief. All of this is far beyond any moral judgment, and for me, it is this untamed, uncontrolled, and boundless power that fascinates me, because it is largely beyond my control. My perception is vast for me, but small for the whole. An important characteristic of my works is the large areas of black and shadow in photographs, installations, and other pieces. I like to preserve this mystery with the darkness; humankind fears it because it fears the unknown. But it is from the darkness that we find the curiosity to invent things, especially existential purposes. There is a lack of acceptance that we are in the dark; we use art, philosophy, and science as a lantern to see some path ahead, but if we go back and illuminate the same place, everything will be different from the last time.
In the last three years, I have traveled many trails in different places such as State Parks, Federal Parks, and private reserves, from where I collected the material for this exhibition. In this process, I gained a clear overview of the preservation of these areas, as they are all seriously threatened. Sometimes it seemed to me that there was a shadow of destruction on my heels, as in the Serra da Canastra National Park, where I witnessed the beginning of a fire that lasted a month after my departure. The place in my photographs no longer exists, not in the same way. From this perspective, it seems that my art is also a testament to this extinction of ecological diversity. During the season I visited, fires don't occur naturally; their origins are criminal, and there's extensive scientific literature on this.
On a smaller scale, we have a government that favors oil exploration at the mouth of the Amazon. I was in Canada and witnessed the commercial logging industry in primary forests. We also saw at COP30 that there's no global willingness to treat environmental issues seriously; that is, much is said, but few seem to truly care about this scenario, with the exception of indigenous peoples of various nationalities. Nor are there any cultural policies aimed at encouraging environmental issues in the artistic field. To the same extent that the multiplicity of our biomes is devastated, sensitivity, imagination, and unique ways of being in the world are also reduced to the same obvious narratives shared on social media, reinforced by algorithms, and ultimately brutalized by the rigid, violent, and lonely daily life of large cities. In this sense, both the nature present in my works and the exhibition itself are similar insofar as, for me, both can be havens where there is some chance for what is different to live, even though increasingly surrounded by monocultures of thought and physicality.
Despite everything, I believe that an art exhibition is not something reactive, but something active that proposes. That is how I would like it to be seen, as a celebration of what deserves to be valued, as an affective sharing between everything that does not surrender to conformity. Finally, I haven't revealed much about what will be found upon visiting it, because what I have said here is only my reading of things, based on my experiences, while art is something else and has nothing to do with that. Art belongs to the world; the works are there for each person to have a different experience, to think for themselves, and to have space to invent and repopulate the world with their own fantasies. A toast to that.
