Sacred geometry is defined as a set of proportions, geometric manipulations and dimensions, as they can be observed in nature and directly transcribed in architectural works or more broadly artistic creations. The human being has been searching for centuries to understand the laws of organization of nature and is inspired by them to add coherence and harmony to his creations. The crystals, the flowers, the fruits, the animals, all these natural elements thus serve as a model for the sacred geometry. Formerly used for the elaboration of religious buildings, this geometry is used here to lay the foundations of a monumental luminous work. His laws, directly inspired by the careful observation of nature, are fertile ground for this artistic research. Indeed, the subliminal pagan evocations here brought to light invite the viewer to serenity and well-being through contemplation.
