The aim of our study is to highlight the obvious similarities that exist between the organizational structures of the biological world, particularly in terms of the number and distribution of the petals on flower and the geometric configurations used by the great masters of European painting, both in the East but also in the West, in order to elaborate the compositional framework of paintings and icons. Taking into consideration the symbolic connotations concerning the field of biology, we chose as a (...) case study the Russian icon from the 14th century entitled “The Triumphal Entry of Jesus into Jerusalem”, exhibited and venerated across the orthodox world on Palm Sunday. Starting with the circle of the aureole of Jesus, we have marked the harmonic series of concentric circles that are distributed across the nodal points of some regular polygons with seven and nine sides, which make reference to the ergonomic formulas of distribution of the petals on a flower and highlight the fact that the beauty of the natural world was and still is the main source of inspiration in the world of arts.
