And the heavens departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
All Commentaries on Revelation 6:14 Go To Revelation 6
George Leo Haydock
AD 1849
And every mountain. In the dreadful confusion of the Roman empire, in the time of Constantine, so great was the revolution, that mountains appeared, as it were, moved out of their places; islands shifted from their accustomed situations. We behold at one time seven persons, Maxim in Galerius, Maxentius, Severus Cæsar, Maxim in, Alexander, Maxim in Hercules, and Licinius, all aiming at the empire. The first six perished in nine years, from 305 to 314: Licinius was strangled in 324. All these were enemies of the Christian religion. Constantine, who supported it, remained sole master of the empire. (Calmet)
