Vita S. Antoni (Life of St. Anthony)

⁶¹ And Archelaus too, the Count, on a time having found him in the outer mountain, asked him merely to pray for Polycratia of Laodicea, an excellent and Christian maiden, for she suffered terribly in the stomach and side through over much discipline, and was altogether weakly of body. Antony prayed therefore, and the Count noted the day in which the prayer was made, and having departed to Laodicea he found the maiden whole. And having enquired when and on what day she was relieved of her infirmity, he produced the paper on which he had written the time of the prayer, and having read it he immediately showed the writing on the paper. And all wondered when they knew that the Lord had relieved her of pain at the time when Antony was praying and invoking the goodness of the Saviour on her behalf.

62. And concerning those who came to him, he often foretold some days or sometimes a month beforehand what was the cause of their coming. For some came only for the sake of seeing him, others through sickness, and others suffering from evil spirits. And all thought the labour of the journey neither trouble nor loss. For each one returned aware that he had received benefit. But though saying such things and beholding such sights, he used to ask that no one should wonder at him for this; but should rather marvel at the Lord for having granted to us men to know Him as far as our powers extended.
