introduce the opening chorus of sea-nymphs ("Prometheus, Woe to thee"), for female voices, arranged in double parts, and set to a restless, agitated accompaniment, expressive of fear and despair. The second prologue, reciting the wrath of Oceanus "on his swift-winged ocean steed," that mortals should have dared to vex his peaceful waters, and the reply of Prometheus that "on the broad earth each place is free to all," introduces the choruses of Tritons and Oceanides. The first is a mixed chorus full of brightness and spirit ("Freedom! afar from Land upon the open Sea"). Their exultant song is followed by a fascinating melody ("Hail! O Prometheus, hail!") for female chorus, with short but expressive solos for soprano and alto ("When to our Waters the golden Time shall come"), the number closing with double chorus in full rich harmony ("Holy and grand and free is the Gift of Heaven"). Thereupon follows the third prologue:-- "Scarcely has ceased the Ocean's song of joy, Which, breathing peace unto Prometheus' soul, Wakens within his breast long-buried hope, When once again the sound of lamentation Bursts on his ear and fills the air with sighs. Seated within a lion-drawn chariot comes The founder of his race--Gæa herself-- With her a train of wood-nymphs, loudly weeping." It introduces a chorus of Dryads ("Woe to thee, Prometheus") of the same general character as the opening chorus of sea-nymphs, and containing a very dramatic and declamatory alto solo ("Deserted stand God's sacred Altars in the old Forest"). A dialogue follows between Gæa and Prometheus, in which the latter bravely defends his course. As the Dryads disappear, Prometheus soliloquizes:-- "'This is, in truth, the noblest deed Mortal has ever dared. Beat high, my heart! On this foundation built I up my race,-- On deathless friendship and fraternity. Courage, Alcides! Bravely fight thy fight. Conquer, and thou shalt free me.' From his dreams, Roused is the Titan by a song of joy. Before him, crowned with the rich harvest, stands Ceres with her train of reapers." A mixed chorus of gleaners follows ("With the Lark sweetly singing"), which can hardly be excelled for grace and loveliness of melody. In the next prologue Ceres consoles Prometheus, and while she is speaking a shout of gladness rises and Bacchus appears. He smites the rock, and at his touch a bower of grape-vines and ivy boughs interlaces over the head of the Titan and shadows him. This serves to introduce the chorus of Vine-dressers ("Hail to the Pleasure-giver"), a lively strain for male voices with an effective solo quartet. As Prometheus resumes his soliloquy, Hermes approaches, leading Pandora, and seeks to allure him from his purpose by her enchantments, but in vain:--
