Vita S. Antoni (Life of St. Anthony)

⁵⁷ Wherefore a man, Fronto by name, who was an officer of the Court and had a terrible disease, for he used to bite his own tongue and was in danger of injury to his eyes, having come to the mountain, asked Antony to pray for him. But Antony said to him, 'Depart and you shall be healed.' But when he was violent and remained within some days, Antony waited and said, 'If you stay here, you can not be healed. Go, and having come into Egypt you shall see the sign wrought in you.' And he believed and went. And as soon as he set eyes on Egypt his sufferings ceased, and the man became whole according to the word of Antony, which the Saviour had revealed to him in prayer.
