Less sombre than 'Lucia,' and quite as tuneful, is 'Lucrezia Borgia,' once a prime favourite at Covent Garden, but now rarely heard. Lucrezia Borgia, the wife of Alfonso of Ferrara, has recognised Gennaro, a young Venetian, as an illegitimate son of her own, and watches over him with tender interest, though she will not disclose the real relation in which they stand to one another. Gennaro, taunted by his friends with being a victim of Lucrezia's fascinations, publicly insults her, and is thereupon condemned to death by the Duke, who is glad of the opportunity of taking vengeance upon the man whom he believes to be his wife's paramour. Gennaro is poisoned in the presence of his mother, who, however, directly the Duke's back is turned, gives him an antidote which restores him to health. In the last act Lucrezia takes comprehensive vengeance upon the friends of Gennaro, whose taunts still rankle in her bosom, by poisoning all the wine at a supper party. Unfortunately Gennaro happens to be present, and as this time he refuses to take an antidote, even though Lucrezia reveals herself as his mother, he expires in her arms. There is little attempt at dramatic significance in the music of 'Lucrezia Borgia,' but the score bubbles over with delicious and wholly inappropriate melodies. Occasionally, as in the final scene, there is a touch of pathos, and sometimes some rather effective concerted music; but, for the most part, Donizetti was content to write his charming tunes, and to leave all expression to the singers. The orchestration of his Italian operas is primitive in the extreme, and amply justifies Wagner's taunt about the 'big guitar.' In works written for foreign theatres Donizetti took more pains, and 'La Favorite,' produced in Paris in 1840, is in many ways the strongest of his tragic works. The story is more than usually repulsive. Fernando, a novice at the convent of St. James of Compostella, is about to take monastic vows, when he catches sight of a fair penitent, and bids farewell to the Church in order to follow her to court. She turns out to be Leonora, the mistress of the King, for whose _beaux yeux_ the latter is prepared to repudiate the Queen and to brave all the terrors of Rome. Fernando finds Leonora ready to reciprocate his passion, and by her means he obtains a commission in the army. He returns covered with glory, and is rewarded by the King, who has discovered his connection with Leonora, with the hand of his cast-off mistress. After the marriage ceremony is over, Fernando hears for the first time of Leonora's past. He flies to the convent for consolation, followed by his unfortunate wife, who dies in his arms after she has obtained forgiveness. 'La Favorite' is more carefully written than was Donizetti's wont, and some of the concerted music is really dramatic. There is a tradition that the last act, which was an after-thought, was written in an incredibly short space of time,
