By a stroke of history, the epic of Don Giovanni begins in Prague. In 1786, Mozart triumphantly presents Les Noces de Figaro and leaves four weeks later with a contract for the next season. The choice of the librettist goes naturally to Da Ponte. To Emperor Joseph II, who doubts the poet's ability to lead the various booklets he is to produce, Da Ponte answers: "I will write the night for Mozart and it will be as if I were reading The Inferno of Dante ... " This comparison is not so extravagant: the two works have the particularity of mixing styles and characters - with Mozart, food and seriousness. This mix of genres is the great strength of Don Giovanni, finding in Mozart's pen a perfect expression. His music, riveted at the word, so versatile and profound at the same time, succeeds in the feat of giving this extraordinary myth a force of reality. At the same time, its complexity and ambiguity are sometimes so great that they leave to the performers and the directors an immense latitude. And it is certainly to this that we recognize universal masterpieces.
