The miracle which was wrought at Milan when I was there, and by which a blind man was restored to sight, could come to the knowledge of many; for not only is the city a large one, but also the emperor was there at the time, and the occurrence was witnessed by an immense concourse of people that had gathered to the bodies of the martyrs Protasius and Gervasius, which had long lain concealed and unknown, but were now made known to the bishop Ambrose in a dream, and discovered by him. By virtue of these remains the darkness of that blind man was scattered, and he saw the light of day.
