"Whilst the holy martyr St. Perpetua was languishing in a dark dungeon she saw the following vision: She beheld a golden ladder which reached from earth to heaven. This ladder was very narrow. On each side were ragged swords, lances, knives, and sharp points of iron. At the foot of the ladder an ungainly monster kept guard to prevent any one from approaching. This vision was meant to show her that she would have to endure suffering and martyrdom for the faith.
"Every maiden who is desirous of preserving her chastity intact may apply this vision to herself. For chastity is a golden ladder which reaches to heaven, but on the right hand and on the left are sharp instruments, namely, enemies, dangers, temptations proceeding from men and from her own fallen nature."
