This book aims to celebrate the 500th anniversary of the death of Leonardo da Vinci in an imaginative journey through unexplored symbolisms of the Salvator Mundi.In an ancient Roman domus, three characters, Louise Deiulio (an astrologer), Chiara Fontecolma (a painter) and Flavio d'Aulico (a surveyor), host the reader in their cultural salons, to accompany him through the folds of the painting, until he reveals the profound sense of Leonardo's much discussed work.In a journey among the celestial bodies of the Ptolemaic system, under the light of the Logos that conquers darkness. Passing from the divine macrocosm to the human microcosm, ending up in the "inner sanctuary" that is revealed in the painting. A real temple, with a kaleidoscopic sanctum: the Leonardesque Christ placed at the center of a multifocal allegorical system.Leonardo's pictorial themes retrace Dante's path to the Empire, following quite articulated mythological paths, alternating with cosmological journeys through the zodiac, in analogy with the labors of Hercules.Guided in this way, one can learn the arts and practice the virtues, recite the Holy Scriptures or declaim the verses of the Divine Comedy. Even contemplating the mystery of the Blood of the Redeemer filling the Holy Grail. In scenarios of alchemical combustion and electromagnetic phenomena, in the harmony of the spheres, while the celestial music of angels with lute resounds. A humanistic path in an anthroposophical key developed through Sunday meetings, in harmony with the rhythms of the year.The Polar Star is the Christ, the Way, the Truth, the Life. The Polar Star is the man who, like Leonardo, cultivates the liberal arts and virtues, putting into practice Dante's motto: "You were not made to live like brutes / but to follow virtue and knowledge."
