The opera opens before the palace at Pherae, where the people are gathered to pray Heaven to spare the life of Admetus, who lies at the point of death. Alcestis appears, and, after an air of great dignity and beauty, bids the people follow her to the temple, there to renew their supplications. The next scene shows the temple of Apollo. The high priest and the people make passionate appeal to the god for the life of their king, and the oracle replies that Admetus must perish, if no other will die in his place. The people, seized with terror, fly from the place, and Alcestis, left alone, determines to give up her own life for that of her husband. The high priest accepts her devotion, and in the famous air 'Divinites du Styx,' she offers herself a willing sacrifice to the gods below. In the original version the second act opened with a scene in a gloomy forest, in which Alcestis interviews the spirits of Death, and, after renewing her vow, obtains leave to return and bid farewell to her husband. The music of this scene is exceedingly impressive, and intrinsically it must have been one of the finest in the opera, but it does not advance the action in the least, and its omission sensibly increases the tragic effect of the drama. In the later version the act begins with the rejoicings of the people at the recovery of Admetus. Alcestis appears, and after vainly endeavouring to conceal her anguish from the eyes of Admetus is forced to admit that she is the victim whose death is to restore him to life. Admetus passionately refuses the sacrifice, and declares that he will rather die with her than allow her to immolate herself on his account. He rushes wildly into the palace, and Alcestis bids farewell to life in an air of extraordinary pathos and beauty. The third act opens with the lamentations of the people for their departed queen. Hercules, released for a moment from his labours, enters and asks for Admetus. He is horrified at the news of the calamity which has befallen his friend, and announces his resolve of rescuing Alcestis from the clutches of Death. Meanwhile Alcestis has reached the portals of the underworld, and is about to surrender herself to the powers of Hell. Admetus, who has not yet given up hope of persuading her to relinquish her purpose, appears, and pleads passionately with her to leave him to his doom. His prayers are vain, and Alcestis is tearing herself for the last time from his arms, when Hercules rushes in. After a short struggle he defeats the powers of Death and restores Alcestis to her husband. The character of Hercules did not appear in the earlier version of the opera, and in fact was not introduced until after Gluck had left Paris, a few days after the production of 'Alceste.' Most of the music allotted to him is probably not by Gluck at all, but seems to have been written by Gossec, who was at that time one of the rising musicians in Paris. The close of the opera is certainly inferior to the earlier parts, but the
