Cosi fan tutte (All the same…) is the third and the last collaboration between Mozart and the librettist Da Ponte, after Le Nozze di Figaro and Don Giovanni. This time, the theme is imposed by Emperor Joseph II in person. Of course, the salon intrigue loses any social connotation, but the opera seduces with his magnificent airs, a paradox between this contribution to the theatre conventions of the Ancient Régime and the Revolution which raged in France. The first performance took place on January 26th, 1790.
