The Book with Seven Seals (Das Buch mit sieben Siegeln) is an oratorio in German by the Austrian composer Franz Schmidt, on themes from the biblical Book of Revelation of Saint John. It was completed in 1937 and first presented in 1938 in Vienna.
The oratorio is arranged in two main parts, with a prologue in heaven.
The principal soloist is Saint John who, as narrator, opens with words of devotion to God the eternal, and to Christ the redeemer. The voice of God (bass) announces that He is the Alpha and Omega, and will show what must come. John then paints the vision of the throne in heaven, the rainbow, the 24 elders, the seven spirits, the sea of glass and the four living creatures. In turn the creatures and the elders sing praises. Angels then ask, who is worthy to open the book with seven seals which is in the hand of Him who sits on the Throne. John observes that no-one is found worthy, but then sees the Lamb that was slain, standing before the throne, that redeemed men with its blood, and John leads and the Chorus repeats and develops the phrases as the Lamb takes the book (Chorus: Die Vision des Lammes). John describes how everything falls down and worships, and introduces the chorus of worship to the Lamb. So ends the prologue.
The first part concerns the opening of the first six seals, and tells the history of Mankind and The Four Horsemen of the Apocalypse. After a great organ passage the first seal is broken, and John describes the appearance of the white horse and its crowned rider. The rider, whom Schmidt interprets as Jesus Christ, announces the Antichrist. He rides as a warrior in righteousness, with his heavenly hosts, to fight in the Name of God. John tells how the Lamb opens the second seal, and the fire-red horse and rider (War) emerges, followed by his hellish hosts, who shall drive all peace from the world, so that men shall all be driven into war against one another. He is given a great sword. Choruses of warriors extolling death and plunder demand that children be torn from their mothers' love and protection, as the women's choruses seek to protect them and cry out their sorrow and torment. (Chorus: Der Krieg)
