ACT II.--A Kermesse or town fair. Groups of students, soldiers, old

men, maids and matrons fill the scene. Valentine, the brother of Marguerite, about to leave for the wars, commends his sister to the care of Siebel, who timidly adores her. While Wagner, a student, is attempting a song, he is interrupted by Mephistopheles who volunteers to sing him a better one (the mocking "Calf of Gold"). Then the fiend causes a fiery liquor to flow miraculously from the tavern sign, and proposes the health of Marguerite. Valentine resents the insult, but his sword is broken in his hand, and Mephistopheles draws a magic circle around himself and bids defiance to the rapiers of the soldiers. These, now suspecting his evil nature, hold their cruciform sword-hilts toward Mephistopheles, who cowers away at the holy symbol. The fête is resumed; in the midst of the revelry Marguerite enters, returning home from church. Faust offers to escort her home, but she timidly declines his assistance, and leaves him enamoured of her beauty. The act closes with a merry dance of the townspeople.
