3. ^The Musical World - Volume 54 - Page 132 1876 Josse's opera, La Lega, at the Scala, has created, at the best, a succes d'estime. Sig. Josse is no longer young, and, judging from his first essay on the lyric stage, I do not fancy he has much chance of distinction. The book, founded upon the elder Dumas' Henri III. et sa Cour, has an exciting plot, and offers some good situations. But the composer has not been happy. He is deficient in originality, and, to atone for this, he borrows from all sources.... Notwithstanding it has been much curtailed, La Lega was more coldly received than on the first performance. Sig. Gayarre and Signora Valleria, however, still distinguish themselves.
