Throughout the history of culture, these domains have been often rigidly framed as opposing forces. Yet, these territories are far from being separate and impermeable: on the contrary, they have always maintained a continuous dialogue, one that has enriched both sides and contributed to a broader and deeper understanding of human experience. Leonardo da Vinci, for example, was not only a painter, but also an engineer, anatomist, and an eminent scholar of philosophia naturalis, and Galileo Galilei, widely regarded as \u201cfather of modern science\u201d, likewise engaged in philosophical and literary reflection. Primo Levi, trained as a chemist, flourished as a writer even if under the pressure of tragic circumstances, shaping his narratives with the same symmetry, precision and lucidity required in the observation of nature (from this approach came works such as <em>If This Is a Man<\/em> and <em>The Periodic Table<\/em>). Finally, Goethe, renowned for his literary and poetic achievements, also pursued investigations in optics and botany, interests that left a rich trace in visual arts - and so one of Turner's most beautiful paintings bears the exact title <em>Light and Colour, Goethe's Theory ...<\/em><\/p>\r\n\r\n<div id=\"attachment_293326\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1.jpg\"><img aria-describedby=\"caption-attachment-293326\" src=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-600x612.jpg\" alt=\"adf-web-magazine-geology-art exhibition-1\" width=\"600\" height=\"612\" class=\"size-ADFwebimage600 wp-image-293326\" srcset=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-600x612.jpg 600w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-294x300.jpg 294w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-1004x1024.jpg 1004w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-147x150.jpg 147w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-768x783.jpg 768w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-230x235.jpg 230w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-392x400.jpg 392w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-490x500.jpg 490w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-686x700.jpg 686w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-500x510.jpg 500w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1-750x765.jpg 750w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-1.jpg 1400w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a><p id=\"caption-attachment-293326\" class=\"wp-caption-text\">Figure 1 J.

Essayist, grammarian, and poet, guided by Cartesian rigour alongside a richly phantasmagorical imagination, Caillois entered UNESCO after the Second World War, a position that allowed him to travel tirelessly across the Americas and Asia. Between 1952 and 1978, these journeys nourished a fervent passion for minerals, leading to the formation of a monumental collection. His fascination for this mineral universe of <em>objets-carrefours<\/em> or <em>objets-f\u00e9es<\/em> was deeply resonant: these entities, placed at the convergence of geology, aesthetics and philosophy, these were not man-made forms, but rather the result of slow and inexorable physical laws, pressures, temperatures and arcane timescales. Yet, this inexorable necessity distilled a gratuitous and silent grace, a form of beauty capable of addressing both rational inquiry and the visual contemplation... <em>L'\u00c9criture des pierres<\/em>, a work Caillois himself characterized as \u201cthe weave of dreams and the chain of knowledge\u201d, gathered the core of his reflections on this subject. In its pages, the seduction of images coexists with the rigorous distance of analysis, holding imagination and critical distance in suspension \u2026 The work was lately published shortly before the death of Caillois in 1978.<a href=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2.jpg\"><img src=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-500x750.jpg\" alt=\" adf-web-magazine-geology-art-exhibition-2.jpg\" width=\"500\" height=\"750\" class=\"aligncenter size-ADFwebimage500 wp-image-293327\" srcset=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-500x750.jpg 500w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-200x300.jpg 200w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-683x1024.jpg 683w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-100x150.jpg 100w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-768x1152.jpg 768w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-1024x1536.jpg 1024w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-1365x2048.jpg 1365w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-230x345.jpg 230w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-267x400.jpg 267w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-333x500.jpg 333w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-467x700.jpg 467w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-600x900.jpg 600w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2-750x1125.jpg 750w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-2.jpg 1400w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/a><br>\r\nHalf a century later, an exhibition at the \u00c9cole des Arts Joailliers in Paris aims to return Caillois to the prominence he once held, presenting more than two hundred objects drawn from his polyhedric collection.<a href=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3.jpg\"><img src=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-500x750.jpg\" alt=\"adf-web-magazine-geology-art exhibition-3\" width=\"500\" height=\"750\" class=\"aligncenter size-ADFwebimage500 wp-image-293328\" srcset=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-500x750.jpg 500w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-200x300.jpg 200w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-682x1024.jpg 682w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-100x150.jpg 100w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-768x1153.jpg 768w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-1024x1536.jpg 1024w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-1365x2048.jpg 1365w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-230x345.jpg 230w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-267x400.jpg 267w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-333x500.jpg 333w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-466x700.jpg 466w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-600x900.jpg 600w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3-750x1126.jpg 750w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-3.jpg 1400w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/a><br>\r\nThe itinerary opens at the point of origin of his inspiration, during his exile in Argentina.

In each affected area, augmented regenerative activity can be observed, which helps redress the impairment, imbalance and asymmetry engendered by the injury. \u2026 I don\u2019t discount the fundamental distinction between inert and living matter. But I also consider how they share common properties, notably the capacity to restore their structural integrity, whether the matter is inert or alive (Roger Caillois)<\/p>\r\n<\/blockquote>\r\n<p><a href=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15.jpg\"><img src=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-500x750.jpg\" alt=\"adf-web-magazine-geology-art exhibition-15\" width=\"500\" height=\"750\" class=\"aligncenter size-ADFwebimage500 wp-image-293324\" srcset=\"https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-500x750.jpg 500w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-200x300.jpg 200w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-683x1024.jpg 683w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-100x150.jpg 100w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-768x1152.jpg 768w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-1024x1536.jpg 1024w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-1365x2048.jpg 1365w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-230x345.jpg 230w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-267x400.jpg 267w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-333x500.jpg 333w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-467x700.jpg 467w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-600x900.jpg 600w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15-750x1125.jpg 750w, https:\/\/www.adfwebmagazine.jp\/wp-content\/uploads\/2026\/02\/adf-web-magazine-geology-art-exhibition-15.jpg 1400w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/a>In conclusion, the exhibition has the merit of inviting the public to discover, as Caillois first did, the hidden and often surprising beauty of the mineral world. Between scientific rigour and poetic imagination, his stones reveal speak directly to the eye and the spirit, in a journey where nature itself becomes art and poetry:<\/p>\r\n<blockquote>\r\n<p class=\"en\">I speak about stones that have always laid outside or that sleep in their deposits, in veins, at night. They have not aroused the interest of the archaeologist, not the artist or the diamond merchant. No palace, statue, jewel, no dyke, embankment or tombstone was built from them. They are neither useful nor famous. Their facets decorate no ring or diadem. They do not bear list of victories, or state laws, in indelible numerals. They are not boundary markers or steel, and do not earn credit or deference from bearing with bad weather. They only attest their own presence. Architecture, sculpture, glyptics, mosaic, jewelry did not utilize them. They date from the beginning of the planet and perhaps emerged from another star. If so, they bear the traces of the space coercion and of their dreadful fall. They arose before mankind; and man, as he developed, did not mark them with his art of with his industry. He did not manufacture them, giving them a somewhat trivial purpose, luxurious or historical. They only perpetuate their own memory [\u2026] I speak about stones that nothing ever altered besides the violence of tectonics and the slow erosion that started with time, with them. I speak about gems, before sculpture, of nuggets before they are melted, of the profound gel of crystals before the intervention of the gem cutter. I speak about stones as algebra, vertigo and order; stones as hymns and quincunxes; stones as stings and corollas, on the brink of dreams, catalyst and image [\u2026] I speak about stones older than \u2013 and which outlast \u2013 life itself, standing on the cold planets on which they came to being. I speak about stones that do not even have to wait for death and that have nothing to do besides letting sand slide on their surfaces, along with rain shower, backwash, storm, and time!
