The flamboyant destiny of the Florentine sculptor Benvenuto Cellini, a misunderstood genius, gave Berlioz the energy to compose his first opera in 1836. It allowed him to identify with the hero of his work: a monumental struggle to create an extraordinary statue, Roman intrigues (well known to Berlioz who had just returned from Villa Medici) and the murder committed by the sculptor arouse dazzling pages in the composer. The powerful choirs evoking the Roman crowds or goldsmiths and the incredibly daringorchestral parts seem utterly innovative. The difficulties of interpretation and the monumentality of Benvenuto Cellini make him a monster both feared and admired.
