I took the trouble to track down one of the claims on the site which said that at the adoption of Nero by Claudius Caesar there was fire in the sky. The site only said that they got this from a historian Cassius Dio. They really could have done better, really could. Well I found him translated into English on Project Gutenberg.
His books are partially preserved and compiled. They are divided into 6 files on Project Gutenberg, so to resolve the above reference you must open volume 5 and then navigate down to two places. In Volume 5 at the place marked book 61 is a description of a glow that appeared around Nero at his birth -- not what the site said, however in the same volume in book 66 subsections 19-23 there is a description of an enormous eruption of Vesuvius for some reason unspecified associated with Neros succession, which was so bright that it caused night and day to be the same. This cannot be called a fulfillment of anything. Plus it includes mysterious stone giants, and these aren't mentioned in Revelation at all.
Anyway the 'Fire in the sky' in Revelation seems to be a figurative description of judgment against rulers rather than something you can fulfill with mere fire. I mean, what does it matter if there's some fire up there? Its just fire.
You wasted your time. All you need to do is ask God and His voice ( the Gospel I preach for God ) will give you an answer to what kind of Fire it written about in Revelation. The "sulfur" smell is the give-a-way word that describes this source of fire.
Revelation 19
20: And the beast was captured, and with it the false prophet who in its presence had worked the signs by which he deceived those who had received the mark of the beast and those who worshiped its image. These two were thrown alive into
the lake of fire that burns with sulfur.
Psalms 18
7: Then the earth reeled and rocked; the foundations also of the mountains trembled and quaked, because he was angry.
8: Smoke went up from his nostrils, and devouring fire from his mouth;
glowing coals flamed forth from him.
9: He bowed the heavens, and came down; thick darkness was under his feet.
10: He rode on a cherub, and flew; he came swiftly upon the wings of the wind.
11: He made darkness his covering around him, his canopy thick clouds dark with water.
12: Out of the brightness before him there broke through his clouds hailstones and
coals of fire.
13: The LORD also thundered in the heavens, and the Most High uttered his voice, hailstones and
coals of fire.
14: And he sent out his arrows, and scattered them; he flashed forth lightnings, and routed them.
15: Then the channels of the sea were seen, and the foundations of the world were laid bare, at thy rebuke, O LORD, at the blast of the breath of thy nostrils.
Joel 2
1: Blow the trumpet in Zion; sound the alarm on my holy mountain! Let all the inhabitants of the land tremble, for the day of the LORD is coming, it is near,
2: a day of darkness and gloom, a day of clouds and thick darkness!
Like blackness there is spread upon the mountains a great and powerful people; their like has never been from of old, nor will be again after them through the years of all generations.
3:
Fire devours before them, and behind them a flame burns. The land is like the garden of Eden before them, but after them a desolate wilderness, and nothing escapes them.
4: Their appearance is like the appearance of horses, and like war horses they run.
5: As with the rumbling of chariots,
they leap on the tops of the mountains, like the crackling of a flame of fire devouring the stubble, like a powerful army drawn up for battle.
6:
Before them peoples are in anguish, all faces grow pale.
7: Like warriors they charge, like soldiers they scale the wall. They march each on his way, they do not swerve from their paths.
8: They do not jostle one another, each marches in his path; they burst through the weapons and are not halted.
9: They leap upon the city, they run upon the walls; they climb up into the houses, they enter through the windows like a thief.
10:
The earth quakes before them, the heavens tremble.
The sun and the moon are darkened, and the stars withdraw their shining.
Revelation 21
8: But as for the cowardly, the faithless, the polluted, as for murderers, fornicators, sorcerers, idolaters, and all liars, their lot shall be in
the lake that burns with fire and sulfur, which is the second death."
