Out of this material the composer has constructed his work, eliminating from and adding to the original matter to suit his musical scheme, but at the same time preserving the general spirit of the story. After a very spirited and energetic prelude, the prologue begins with the fruitless attempt of Lucifer to pull down the cross on the spire of Strasburg cathedral, the protests of the spirits of the air (first and second sopranos), the defiance of the bells (male chorus) as each attempt fails, and the final disappearance of the spirits amid the chanting of the majestic Latin hymn, "Nocte surgentes," by full chorus in the church, accompanied by the organ. The second scene opens in Prince Henry's chamber in the tower of the Vautsberg castle, and reminds one of the opening scene of "Faust," as set by Gounod. After an expressive declamation of his melancholy and his longing for rest and health ("I cannot sleep, my fervid Brain calls up the vanished Past again"), Lucifer appears in a flash of light, dressed as a travelling physician, and a dialogue ensues, the purport of which has already been told, which closes with an ingenious and beautifully-written number for the two voices, accompanied by a four-part chorus of mixed voices and a small semi-chorus of sopranos and altos ("Golden Visions wave and hover"). The fourth scene is an unaccompanied quartet, "The Evening Song," sung by Elsie, Bertha, Max, and Gottlieb in their peasant home in the Odenwald, as they light the lamps ("O gladsome Light of the Father"). It is a simple, tranquil hymn, but full of that sacred sentiment which this composer expresses so admirably in music. The fifth scene, Elsie's prayer in her chamber ("My Redeemer and my Lord"), in its calm beauty and religious feeling makes a fitting pendant to the quartet. In the next number, the orchestra is utilized to carry on the action, and in march tempo describes the pilgrimage to Salerno with stately intervals, in which is heard the sacred song, "Urbs coelestis, urbs beata," supposed to be sung by the pilgrims "moving slowly on their long journey with uncovered feet." The seventh scene is laid in the refectory of the convent of Hirschau, in the Black Forest, where Lucifer enters the gaudiolum of monks, disguised as a friar, and sings the rollicking Latin drinking-song, "Ave color vini clari," which Mr. Edmund C. Stedman versified for this work as follows:-- "Hail! thou vintage clear and ruddy! Sweet of taste and fine of body, Through thine aid we soon shall study How to make us glorious! "Oh! thy color erubescent! Oh! thy fragrance evanescent! Oh! within the mouth how pleasant! Thou the tongue's prætorius! "Blest the stomach where thou wendest! Blest the throat which thou distendest! Blest the mouth which thou befriendest, And the lips victorious! Chorus of Monks.
