9 To pursue my proposed story. Antony traversed the region on which he had entered, seeing only the traces of wild beasts, and the wide waste of the desert. What to do, whither to wend his way, he knew not. Another day had now passed. One thing alone was left him, his confident belief that he could not be forsaken by Christ. The darkness of the second night he wore away in prayer. While it was still twilight, he saw not far away a she-wolf gasping with parching thirst and creeping to the foot of the mountain. He followed it with his eyes; and after the beast had disappeared in a cave he drew near and began to look within. His curiosity profited nothing: the darkness hindered vision. But, as the Scripture says, perfect love casts out fear. With halting step and bated breath he entered, carefully feeling his way; he advanced little by little and repeatedly listened for the sound. At length through the fearful midnight darkness a light appeared in the distance. In his eager haste he struck his foot against a stone and roused the echoes; whereupon the blessed Paul closed the open door and made it fast with a bar. Then Antony sank to the ground at the entrance and until the sixth hour or later craved admission, saying, “Who I am, whence, and why I have come, you know. I know I am not worthy to look upon you: yet unless I see you I will not go away. You welcome beasts: why not a man? I asked and I have found: I knock that it may be opened to me. But if I do not succeed, I will die here on your threshold. You will surely bury me when I am dead.”
Such was his constant cry: unmoved he stood.
To whom the hero thus brief answer made
“Prayers like these do not mean threats; there is no trickery in tears. Are you surprised at my not welcoming you when you have come here to die?” Thus with smiles Paul gave him access, and, the door being opened, they threw themselves into each other's arms, greeted one another by name, and joined in thanksgiving to God.
