Domenico�Cimarosa's�operas were remarkably successful, being staged and re-staged in opera houses all over Europe. Success in his�hometown�of Naples led to court appointments and royal commissions, including his best-known work Il�matrimonio�segreto�('The Secret Marriage') composed for Austrian emperor Leopold II. Other hits include�L'impegno�superato�('The Broken Engagement'), an instant success and soon to become one of the most frequently performed of�Cimarosa's�comic works, and Penelope that was produced as far away as London in 1817. The Cantata per Ferdinando IV was, however, written as an act of repentance,�Cimarosa�having made the mistake of backing the failed republican government in 1799.
