(_h_) In his thirty-fourth book Timaeus says that “he spent fifty continuous years at Athens as an alien, and never took part in any military service, or went to inspect the localities.” Accordingly, when he comes upon any such matters in the course of his history, he shows much ignorance and makes many misstatements; and if he ever does come near the truth, he is like one of those animal-painters who draw from models of stuffed skins. Such artists sometimes preserve the correct outline, but the vivid look and life-like portraiture of the real animal, the chief charm of the painter’s art, are quite wanting. This is just the case with Timaeus, and in fact with all who start with mere book-learning; there is nothing vivid in their presentment of events, for that can only come from the personal experience of the writers. And hence it is, that those who have gone through no such course of actual experience produce no genuine enthusiasm in the minds of their readers. Former historians showed their sense of the necessity of making professions to this effect in their writings. For when their subject was political, they were careful to state that the writer had of course been engaged in politics, and had had experience in matters of the sort; or if the subject was military, that he had served a campaign and been actually engaged; and again, when the matter was one of everyday life, that he had brought up children and had been married; and so on in every department of life, which we may expect to find adequately treated by those writers alone who have had personal experience, and have accordingly made that branch of history their own. It is difficult perhaps for a man to have been actually and literally engaged in everything: but in the most important actions and most frequently occurring he must have been so.
