In the Book of Revelation, seven trumpets are sounded, one at a time, to cue apocalyptic events seen by John of Patmos (Revelation 1:9) in his vision (Revelation 1:1). The seven trumpets are sounded by seven angels and the events that follow are described in detail from Revelation Chapters 8 to 11. According to Revelation 8:1–2 the angels sound these trumpets after the breaking of the seventh seal. These seals secured the apocalyptic document held in the right hand of Him who sits on the throne.[1] The trumpets are referred to in Koine Greek as σάλπιγξ (sálpinx, salpinx); this was a straight, narrow bronze tube with a mouthpiece of bone and a bell; they do not closely resemble modern valve trumpets. The final three trumpets are sometimes called the "woe trumpets".[2]
