In an anonymous eve, after a small accident in the home, the author is illuminated by an almost mystic revelation. Afterwards he started to understand the mystery of Alchemy, its Universal Laws, and the forces that elevate man over his own destiny, and Lastly the messages that Leonardo has left in his Art. And he takes as a reference point various paintings that mark the excursus of the artist, starting from the first works who still suffer from the teachings of Verrocchio (as Madonna of the Carnation) up to the maturity portraits. In each of these paintings the author recognizes and can interpret the Alchemic Keys which the Master has written in code.
