15 Facidia is a hamlet belonging to Rhino-Corura, a city of Egypt. From this village a woman who had been blind for ten years was brought to the blessed Hilarion, and on being presented to him by the brethren (for there were now many monks with him) affirmed that she had spent all her substance on physicians. The saint replied: “If you had given to the poor what you have wasted on physicians, the true physician Jesus would have cured you.” But when she cried aloud and entreated pity, he spat into her eyes, in imitation of the Saviour, and with similar instant effect.
