Legatio Ad Gaium

for Apollo is said to have been not only a physician but also an excellent prophet, by his oracular predictions announcing what was likely to conduce to the advantage of mankind, in order that no one, being overshadowed by uncertainty, going on without seeing his way before him like a blind man, might hastily fall into unexpected evils as if they were the greatest benefits; but that men having previously acquired a knowledge of the future as if it were really present, and looking at it with the eye of their mind, might guard against future evils just as they can see evils actually before them with the bodily eye, and in this way secure themselves against any irremediable disaster.
