Nicene and Post-Nicene Fathers, Ser. II, Vol. IV:
Life of Antony. (Vita Antoni.): Section 70

70. All the people, therefore, rejoiced when they heard the anti-Christian heresy anathematised by such a man. And all the people in the city ran together to see Antony; and the Greeks and those who are called their Priests, p. 215 came into the church, saying, ‘We ask to see the man of God,’ for so they all called him. For in that place also the Lord cleansed many of demons, and healed those who were mad. And many Greeks asked that they might even but touch the old man, believing that they should be profited. Assuredly as many became Christians in those few days as one would have seen made in a year. Then when some thought that he was troubled by the crowds, and on this account turned them all away from him, he said, undisturbedly, that there were not more of them than of the demons with whom he wrestled in the mountain.

71. But when he was departing, and we were setting him forth on his way, as we 1119 arrived at the gate a woman from behind cried out, ‘Stay, thou man of God, my daughter is grievously vexed by a devil. Stay, I beseech thee, lest I too harm myself with running.’ And the old man when he heard her, and was asked by us, willingly stayed. And when the woman drew near, the child was cast on the ground. But when Antony had prayed and called upon the name of Christ, the child was raised whole, for the unclean spirit was gone forth. And the mother blessed God, and all gave thanks. And Antony himself also rejoiced, departing to the mountain as though it were to his own home.
