Seven trumpets are sounded, one at a time, to cue apocalyptic events that were seen in the vision of the Revelation of Christ Jesus, by John of Patmos, as written in the Book of Revelation of the New Testament. The seven trumpets are sounded by seven angels and the events that follow are described in detail from Revelation Chapters 8 to 11. Alt meaning for muted horn - blocking the apocalypse.
