Sources. The chief writers in this period are: For the history of the Persian wars to the battle of Plataeae, 479, Herodotus. For the period between 479 and the breaking out of the Peloponnesian war, we must, in the absence of contemporary authors, consider Diodorus Siculus as the principal authority.--The beginning of the 11th book, which commences with the year 480, (the 6th, 7th, 8th, 9th, and 10th books being lost,) to the middle of the 12th; the chronology of this author, however, must in several cases be rectified after Thucydides's summary in lib. i. For the period of the Peloponnesian war, 431-410, the history of Thucydides is the capital work; but it must be accompanied by Diodorus, from the middle of the 12th book to the middle of the 13th.--From the year 410 to the battle of Mantinea, 362, the principal sources are the Hellenics of Xenophon, and occasionally his Anabasis and Agesilaus; together with Diodorus, from the middle of the 13th book to the end of the 15th. For the years intervening from 362-336, no contemporary historian has been preserved; Diodorus's 16th book must therefore here be considered as the chief source: for the times of Philip, however, recourse may likewise be had to the speeches of Demosthenes and Aeschines. The Lives of Plutarch and Nepos often touch upon this period, but cannot be regarded as authentic sources; of still less authority are the abridged documents given by Justin and some others. The modern authors on this, the brilliant period of Greece, are, of course, the same as have been enumerated above: (see p. 118.) To whom must here be added: POTTER, _Archaeologia Graeca; or the Antiquities of Greece:_ 2 vols. 8vo. Lond. 1722. Translated into German by J. J. Rambach, 3 vols. 1775. BARTHELEMY, _Voyage du Jeune Anacharsis en Grece_. (Between the years B. C. 362 and 338.) Paris, 1788, 5 vols. Accompanied with charts and plans, illustrating the topography of Athens, etc. This work is conspicuous for a rare union of good taste and erudition; unattended, however, with an equal share of critical acumen and a correct appreciation of antiquity. # _History of the Origin, Progress, and Fall of Science in Greece and Rome_, by C. MEINERS. Gottingen, 1781. It contains also a delineation of the political state of affairs; but does not extend beyond the age of Philip. The principal works on the monuments of ancient Greece are: LE ROY, _Les Ruines des plus beaux Monumens de la Grece_. Paris, 1758, 2nd edit. 1770, fol. The first in point of time; but far surpassed by: J. STUART, _The Antiquities of Athens measured and delineated_; 3 vols. Lond. 1762: the 4th vol. published in 1816. In beauty and accuracy of execution superior to all. R. DALTON, _Antiquities and Views of Greece and Egypt_, 1691, fol. The Egyptian monuments are confined to those of Lower Egypt.
