(Χρυσόχοος), a poor man at Alexandria, who may have lived between the fifth and tenth centuries after Christ, of whom a story is told by Nicolaus Myrepsus. (De Compos. Medicam. 24.60, 85, pp. 664, 666.) At the age of thirty-two he lost his sight, upon which he went to a chapel of the Blessed Virgin to offer up prayers for his recovery. Here he is said to have been directed to a place where he would find a written paper, which contained a prescription for making an eye-wash; by means of which he was himself restored to sight, and also gained a large income by healing others. At his death he gave the prescription to one of his daughters, and it has been preserved by Nicolaus Myrepsus.
