I. The narrative of Tacitus is delivered in these terms: "One of the common people of Alexandria, known to be diseased in his eyes, by the admonition of the god Serapis, whom that superstitious nation worship above all other gods, prostrated himself before the emperor, earnestly imploring from him a remedy for his blindness, and entreating that he would deign to anoint with his spittle his cheeks and the balls of his eyes. Another, diseased in his hand, requested, by the admonition of the same god, that he might be touched by the foot of the emperor. Vespasian at first derided and despised their application; afterwards, when they continued to urge their petitions, he sometimes appeared to dread the imputation of vanity; at other times, by the earnest supplication of the patients, and the persuasion of his flatterers, to be induced to hope for success. At length he commanded an inquiry to be made by the physicians, whether such a blindness and debility were vincible by human aid. The report of the physicians contained various points: that in the one, the power of vision was not destroyed, but would return if the obstacles were removed; that in the other, the diseased joints might be restored, if a healing power were applied; that it was, perhaps, agreeable to the gods to do this; that the emperor was elected by divine assistance; lastly, that the credit of the success would be the emperor's, the ridicule of the disappointment would fall upon the patients. Vespasian believing that everything was in the power of his fortune, and that nothing was any longer incredible, whilst the multitude which stood by eagerly expected the event, with a countenance expressive of joy, executed what he was desired to do. Immediately the hand was restored to its use, and light returned to the blind man. They who were present relate both these cures, even at this time, when there is nothing to be gained by lying."
