Note 445:2 — Chapter XXXVII
Reading edition
"Constantine, as he was praying about noon-tide, God showed him a vision in the sky, which was the sign of the cross lively figured in the air, with this inscription on it: 'In hoc vince;' that is, 'By this overcome.'" This is the story as related by Eusebius (Life of Constantine, lib. 1, ch. xxii.), but it must be remembered that Eusebius acknowledged that he told falsehoods. That night Christ appeared unto Constantine in his dream, and commanded him to make the figure of the cross which he had seen, and to wear it in his banner when he went to battle with his enemies. (See Eusebius' Life of Constantine, lib. 1, ch. xxiii. See also, Socrates: Eccl. Hist., lib. 1, ch. ii.)
