And here one may mention with admiration that Homer represents Ulysses, that truest type of a leader of men, taking observations of the stars, not only to direct his voyages, but his operations on land also. For such accidents as baffle expectation, and are incapable of being accurately reckoned upon, are quite sufficient to bring us to great and frequent distress, for instance, downpours of rain and rise of torrents, excessive frosts and snows, misty and cloudy weather, and other things like these;—but if we also neglect to provide for those which can be foreseen, is it not likely that we shall have ourselves to thank for frequent failures? None of these means then must be neglected, if we wish to avoid those errors into which many others are said to have fallen, as well as the particular generals whom I am about to mention by way of examples.
