The advocates for the vision are unable to produce a single testimony from the Fathers of the fourth and fifth centuries, who in their voluminous writings repeatedly celebrate the triumph of the church and of Constantine. As these venerable men had not any dislike to a miracle, we may suspect (and the suspicion is confirmcd by the ignorance of Jerom) that they were all unacquainted with the Life of Constantine by Eusebius. This tract was recovered by the diligence of those who translated or continued his Ecclesiastical History, and who have represented in various colours the vision of the cross.
