Not the least remarkable feature in recent historical criticism is the reaction against the view which was at one time almost universally accepted of the character, statesmanship and authority of the orator Demosthenes (q.v.). During the last quarter of a century his character and statesmanship have been attacked, and his authority impugned, by a series of writers of whom Holm and Beloch are the best known. With the estimate of his character and statesmanship we are not here concerned. With regard to his value as an authority for the history of the period, it is to his speeches, and to those of his contemporaries, Aeschines, Hypereides, Dinarchus and Lycurgus, that we owe our intimate knowledge, both of the working of the constitutional and legal systems, and of the life of the people, at this period of Athenian history. From this point of view his value can hardly be overestimated. As a witness, however, to matters of fact, his authority can no longer be rated as highly as it once was, e.g. by Schaefer and by Grote. The orator's attitude towards events, both in the past and in the present, is inevitably a different one from the historian's. The object of a Thucydides is to ascertain a fact, or to exhibit it in its true relations. The object of a Demosthenes is to make a point, or to win his case. In their dealings with the past the orators exhibit a levity which is almost inconceivable to a modern reader. Andocides, in a passage of his speech _On the Mysteries_ (§ 107), speaks of Marathon as the crowning victory of Xerxes' campaign; in his speech _On the Peace_ (§ 3) he confuses Miltiades with Cimon, and the Five Years' Peace with the Thirty Years' Truce. Though the latter passage is a mass of absurdities and confusions, it was so generally admired that it was incorporated by Aeschines in his speech _On the Embassy_ (§§ 172-176). If such was their attitude towards the past; if, in order to make a point, they do not hesitate to pervert history, is it likely that they would conform to a higher standard of veracity in their statements as to the present--as to their contemporaries, their rivals or their own actions? When we compare different speeches of Demosthenes, separated by an interval of years, we cannot fail to observe a marked difference in his statements. The farther he is from the events, the bolder are his mis-statements. It is only necessary to compare the speech _On the Crown_ with that _On the Embassy_, and this latter speech with the _Philippics_ and _Olynthiacs_, to find illustrations. It has come to be recognized that no statement as to a matter of fact is to be accepted, unless it receives independent corroboration, or unless it is admitted by both sides. The speeches of Demosthenes may be conveniently divided into four classes according to their dates. To the pre-Philippic period belong the speeches _On the Symmories_ (354 B.C.), _On Megalopolis_ (352 B.C.), _Against Aristocrates_ (351 B.C.), and, perhaps, the speech _On Rhodes_ (? 351 B.C.). These speeches betray no consciousness of the danger threatened by Philip's ambition. The policy recommended is one based upon the principle of the balance of power. To the succeeding period, which ends with the peace of Philocrates (346 B.C.), belong the _First Philippic_ and the three _Olynthiacs_. To the period between the peace of Philocrates and Chaeronea belong the speech _On the Peace_ (346 B.C.), the _Second Philippic_ (344 B.C.), the speeches _On the Embassy_ (344 B.C.) and _On the Chersonese_ (341 B.C.), and the _Third Philippic_. The masterpiece of his genius, the speech On the Crown, was delivered in 330 B.C., in the reign of Alexander. Of the three extant speeches of Aeschines (q.v.) that _On the Embassy_ is of great value, as enabling us to correct the mis-statements of Demosthenes. For the period from the death of Alexander to the fall of Corinth (323-146 B.C.) our literary authorities are singularly defective. For the Diadochi Diodorus (books xviii.-xx.) is our chief source. These books form the most valuable part of Diodorus' work. They are mainly based upon the work of Hieronymus of Cardia, a writer who combined exceptional opportunities for ascertaining the truth (he was in the service first of Eumenes, and then of Antigonus) with an exceptional sense of its importance. Hieronymus ended his history at the death of Pyrrhus (272 B.C.), but, unfortunately, book xx. of Diodorus' work carries us no farther than 303 B.C., and of the later books we have but scanty fragments. The narrative of Diodorus may be supplemented by the fragments of Arrian's _History of the events after Alexander's death_ (which reach, however, only to 321 B.C.), and by Plutarch's _Lives of Eumenes_ and of _Demetrius_.
