Fallen Angels

Et cauda ejus habebat tertiam partem stellarum coeli, et misit illas in terram. Quod autem dicit draconis caudam traxisse tartiam partem stellarum coeli, bifariam hoc accipi potest; multi enim arbitrantur tertiam partem hominum credentium posse cum seducere. Sed quod verius intelligi debeat angelorum sibi subditorum eum adhuc principes esset, cum descenderet constitutione sua, tertiam partem seduxisse. Victorinus Petavionensis, Scoli in Apocalypsin Beati Joannis, Caput XII Source: Migne PL 5.336c

And his tail grasped a third part of the stars of heaven and cast them down to earth. 1 Here it says that the tail of the dragon dragged down a third part of the stars from heaven, and in two ways this can be understood. Many judge that he is able to seduce a third part of the faithful. But more accurately it should be understood that when he was prince a third part of the angels were under his command, and when he fell from his place, he drew down a third part with him.  Victorinus of Pettau, from the Commentary on the Apocalypse of St John, Chapter 12 1 Apoc 12.4
