I will now state my reasons for disagreeing with this division. One is that even the bolt which is called constant lasts for a limited period. Such bolts correspond no less than others to a definite date. Nor do they cease to be limited because the period they signify is a long one. So, too, what is thought to be deferred is limited. For by the admission of the advocates of this division the period for which delay can be procured is a definite one. Bolts that relate to private matters cannot, according to them, be delayed longer than ten years, those relating to public affairs not more than thirty. So this class, as well as the first, is limited, as it includes the date beyond which the prognostication cannot be deferred. There is thus a fixed period for bolts and results of every kind. For of what is uncertain there could be no distinct knowledge. Then, too, these people talk in too vague and general terms about the points to be noted in lightning. They ought rather to divide them according to the scheme of the philosopher Attalus, who had specialised in this department. The inspection should determine where the lightning occurred, when, to whom, in what connection, of what kind, of what amount. If I were to attempt to arrange and classify all these, I should just be committing myself to an endless task.
