Second trumpet: a great burning mountain plunges into the sea. Beatus de Facundus, 1047.
The Fourth Angel sounds his trumpet, Apocalypse 8. Beatus Escorial.
Upon the first trumpet sound, hail and fire, mixed with blood, is thrown to the Earth burning up a third of the trees on the planet, and all green
grass. (Revelation 8:7)
By the second trumpet sounding, it cues something like a great burning mountain that plunges into the sea and wipes out a third of all sea life and
ships. A third of the oceans will become blood. (Revelation 8:8-9)
By the sound of the third trumpet, a great star called Wormwood falls to the Earth poisoning a third of the planet's freshwater sources, such as
rivers and springs. Men will die from drinking its bitter taste. (Revelation 8:10-11)
Following the sounding of the fourth trumpet, a third of the light that shines from the Sun, moon and stars became dark from these celestial bodies
being "struck". This catastrophe caused complete darkness for a third of a day, during the day, even through night hours.(Revelation 8:12)
The fifth trumpet sound is the "first Woe" of three. Before this trumpet sounds, an angel (translated eagle in some versions) appears, flying in
mid-heaven, and warns, "Woe, woe, woe, to those who dwell on the earth, because of the remaining blasts of the trumpet of the three angels who are
about to sound!" 
The fifth trumpet prompts a personified star to fall from heaven. The star is given the key to the bottomless pit. After opening it, the smoke that
rises out, darkens the air and blocks the sunlight. Then from out of the smoke, the Locusts were unleashed. They were scorpion tailed warhorses,
having a man's face with lion's teeth. Their hair was long like that of a woman's and flew with locust-like wings. They were crowned with golden
crowns and protected with iron-like breastplates. They were commanded by their king, Abaddon, to torment any man who does not have the seal of God on
their forehead, by using their scorpion-like tails. It was also made clear to them that they must not kill anyone during their five-month mission of
torment. (Revelation 9:1-12)
Robert Witham, a Catholic commentator, issued his two-volume Annotations on the New Testament, in 1733. Commenting on Chapter 9, he offers two
preterist views for identifying the locusts with scorpion tails.
The locusts may have represented the incursion of the Goths and “those barbarous People” that interrupted the Roman Empire during the time of
The locusts may have represented the Jewish heretics who denied Christ. Most notably, Theodotus, Praxeas, Noetus, Paul of Samosata, Sabellius, and
Seventh Trumpet, Bamberg Apocalypse, circa 1010.
Five months after the fifth trumpet blast, the sixth one sounds. This is the "Second woe", where four angels are released from their binds to the
"great river Euphrates". They command a brute force of 200 million mounted troops whose horses dissipate plague from out of their mouths, most
notably: fire, smoke, and brimstone. The mounted horsemen wore breastplates with the color of fire, hyacinth, and brimstone. The horses had a lion's
head and their tails were like a serpent, even with a snake head. They are responsible for the deaths of a third of mankind who are striken by the
plague that emanated from these armies. (Revelation 9:13-21)
The sound of the seventh trumpet signals the "Third woe". This is the final trumpet sound and the final woe. Loud voices in heaven proclaim Christ
as ruler forever and ever under the "Kingdom of our Lord". Thanks is given to God, the Almighty and praise for the wrath that came, the dead who
were judged, and the bond-servants rewarded. The temple of God in heaven then opened and the Ark of the covenant appeared in His temple. Then
lightning and peals of thunder occurred followed by an earthquake and a great hailstorm. (Revelation 11:15-19)
