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 Book of Revelation, the final book of the New Testament, contains a prophetic vision of the end of the present world, the Last Judgement, and the coming of the New Jerusalem. The Book with Seven Seals is opened by the enthroned Lamb of God in the presence of the twenty-four elders. The number seven corresponds to the seven spirits of God, and the sevenfold nature of the divine order in the world. As each of the seals is opened in turn, the events and catastrophes leading to the dissolution of the world are set in motion. (Revelation, Chapters IV - VII) The oratorio takes the entire sacred narrative of the Book of Revelation as its subject, using selected texts. Through the narrator (tenor), the celestial symbology is introduced as visionary material, while the solo voices, ensembles and choruses enact scenes and responses to events as they unfold. The score employs full orchestral resources including passages for solo pipe organ.
