There is a story, that once Pericles had brought to him from a country farm of his, a ram's head with one horn, and that Lampon, the diviner, upon seeing the horn grow strong and solid out of the midst of the forehead, gave it as his judgment, that, there being at that time two potent factions, parties, or interests in the city, the one of Thucydides and the other of Pericles, the government would come about to that one of them in whose ground or estate this token or indication of fate had shown itself. But that Anaxagoras, cleaving the skull in sunder, showed to the bystanders that the brain had not filled up its natural place, but being oblong, like an egg, had collected from all parts of the vessel which contained it, in a point to that place from whence the root of the horn took its rise. And that, for that time, Anaxagoras was much admired for his explanation by those that were present; and Lampon no less a little while after, when Thucydides was overpowered, and the whole affairs of the state and government came into the hands of Pericles. And yet, in my opinion, it is no absurdity to say that they were both in the right, both natural philosopher and diviner, one justly detecting the cause of this event, by which it was produced, the other the end for which it was designed. For it was the business of the one to find out and give an account of what it was made, and in what manner and by what means it grew as it did; and of the other to foretell to what end and purpose it was so made, and what it might mean or portend. Those who say that to find out the cause of a prodigy is in effect to destroy its supposed signification as such, do not take notice that, at the same time, together with divine prodigies, they also do away with signs and signals of human art and concert, as, for instance, the clashings of quoits, fire-beacons, and the shadows on sun-dials, every one of which things has its cause, and by that cause and contrivance is a sign of something else. But these are subjects, perhaps, that would better befit another place.
