Among the works of Xenophon is the Anab'asis, considered his best, descriptive of the advance into Persia and the masterly retreat; the Hellen'ica, a history of Greece, in seven books, from the time of Thucydides to the battle of Mantine'a, in 362 B.C.; the Cyropoedi'a, a political romance, based on the history of Cyrus the Great; a treatise on the horse, and the duties of a cavalry commander; a treatise on hunting; a picture of an Athenian banquet, and of the amusement and conversation with which it was diversified; and, the most pleasing of all, the Memorabil'ia, devoted to the defence of the life and principles of Socrates. Concerning the remarkable miscellany of Xenophon, MR. MITCHELL says: "The writer who has thrown equal interest into an account of a retreating army and the description of a scene of coursing; who has described with the same fidelity a common groom and a perfect pattern of conjugal faithfulness--such a man had seen life under aspects which taught him to know that there were things of infinitely more importance than the turn of a phrase, the music of a cadence, and the other niceties which are wanted by a luxurious and opulent metropolis. The virtuous feelings that were necessary in a mind constituted as his was, took into their comprehensive bosom the welfare of the world." Although the genius of Xenophon was not of the highest order, his writings have afforded, to all succeeding ages, one of the best models of purity, simplicity, and harmony of language: By some of his contemporaries he has been styled "The Attic Muse;" by others, "The Athenian Bee;" while his manners and personal appearance have been described by Diog'enes Laer'tius, in his Lives of the Philosophers, in the following brief but comprehensive sentence: "Modest in deportment, and beautiful in person to a remarkable degree." POLYB'IUS.
