Botany, religion, mathematics and art: four chapters that decline the crowd of the anglings from which we can observe and analyse the palm tree, "essential element of perfection and happiness." "mother and sacred origin of the life."It is able to transmit us, the "harmonious image that accompanies the look beyond the perception," it becomes the excellency of all pan religious symbols. We finds again the palm tree represented in the Renaissance pictures as in the Indian art, in the algebraic formulas and in the gardens of the most splendid buildings of the world. "The light head of its hair, at times dense of fruits, is composed by spiral from a forgetful stem of the height, evoking dizzy exactness and delicate decorations."
