Lightning portends the future, too. Nor do the signs it gives refer to only one or two events. Often a complete series of fate’s succeeding decrees is intimated, with proof, too, plain to demonstration, far more distinct than if it were recorded in writing. There are differences of interpretation, however, between our countrymen and the Tuscans, the latter of whom possess consummate skill in the explanation of the meaning of lightning. We think that because clouds collide, therefore lightning is emitted; they hold that clouds collide in order that lightning may be emitted. They refer everything to the will of God: therefore they are strong in their conviction that lightning does not give an indication of the future because it has occurred, but occurs because it is meant to give this indication. Whether the indication is its purpose or its consequence makes no difference in the method of its occurrence. How, then, do they give indication unless they are sent by God? Just in the same way as birds give favourable or unfavourable omens, though they are not moved on their flight for the express purpose of meeting us. God moves them too, it is urged. You imagine He has so little to do that He can attend to trifles of this sort, if you will have Him arrange visions for one, entrails of victims for another.

Nevertheless, all those things are managed by Divine agency, not, however, in the sense that the wings of birds are immediately directed by God, or the bowels of cattle arranged by Him in certain forms under the priest’s axe. It is in far other way that the roll of fate is unfolded; it sends ahead in all directions intimations of what is to follow, which are in part familiar, in part unknown to us. Everything that happens is a sign of something that is going to happen: mere chance occurrences uncontrolled by any rational principle do not admit of the application of divination. An event that belongs to a series thereby becomes capable of being predicted. But why, then, is the honour conferred upon the eagle of giving omens concerning great events? or a similar function assigned to the raven and a very few other birds, while all the rest give no presage by their notes? The reason simply is that some departments have not yet been brought within the sphere of the art of augury, while some are incapable of ever being brought within it, because our acquaintance with them is too slight.

As a matter of fact, there is no living creature whose movement or meeting with us does not foretell something. Of course, only some, not all, can be observed. The omen lies in the observation. So it concerns the person who directs his attention to it. But other things as well concern him, though they pass unheeded. For instance, the Chaldaeans confined their observation to the five great planets. But do you suppose that the influence of so many thousands of other bright stars is naught? The essential error of those who pretend to skill in casting the horoscope lies in limiting our destinies to the influence of a few of the stars, while all that float above us in the heavens claim some share in us. Perchance the lower stars exert their force on us more directly; and47 the same may be true of the stars that by reason of their more frequent movements turn their view upon man in a different way from that in which it is turned upon other living creatures. But even those stars that are either stationary or, from their velocity being the same as that of the world as a whole, seem to be so, are not without sway and dominion over us. Add one other consideration and you have the subject set out with due arrangement of its parts:48 it is not more easy to ascertain what the power of the stars is than justifiable to doubt that they possess such power.
