Inspired by the musical drama of Richard Wagner, the jewel contains all the symbolic richness and the intertwining of philosophical, literary and religious elements, of which the work is composed: the Holy Grail, the Holy Lance, the flower girls, Kundry and the evil Klingsor.
On the reverse, the artist interprets Wagner's cosmic music, with Empedocles' four elements: air (the cherub), fire (the flames), water (the dolphin), earth (the snail), and above human things, God, Alpha and Omega, creator of the immensity, who loves men in whose heart the dove of peace beats, as in the jewel. And again, above, the stars, the sun and life.
