32 Having returned to Aphroditon and keeping with him only two of the brethren, he stayed in the neighbouring desert, and practised such rigid abstinence and silence that he felt that then for the first time he had begun to serve Christ. Three years had now elapsed since the heavens had been closed and the land had suffered from drought, and it was commonly said that even the elements were lamenting the death of Antony. Hilarion did not remain unknown to the inhabitants of that place any more than to others, but men and women with ghastly faces and wasted by hunger earnestly entreated the servant of Christ, as being the blessed Antony's successor, to give them rain.
Hilarion when he saw them was strangely affected with compassion and, raising his eyes to heaven and lifting up both his hands, he at once obtained their petition. But, strange to say, that parched and sandy district, after the rain had fallen, unexpectedly produced such vast numbers of serpents and poisonous animals that many who were bitten would have died at once if they had not run to Hilarion. He therefore blessed some oil with which all the husbandmen and shepherds touched their wounds, and found an infallible cure.
