[Xenophon], historian, philosopher, and military commander, born at Athens, son of an Athenian of good position; was a pupil and friend of Socrates; joined the expedition of Cyrus against his brother Artaxerxes, and on the failure of it conducted the ten thousand Greeks—"the Retreat of the Ten Thousand"—who went up with him back to the Bosphorus, served afterwards in several military adventures, brought himself under the ban of his fellow-citizens in Athens, and retired to Elis, where he spent 20 years of his life in the pursuits of country life and in the prosecution of literature; the principal of his literary works, which it appears have all come down to us, are the "Anabasis," being an account in seven books of the expedition of Cyrus and his own conduct of the retreat; the "Memorabilia," in four books, being an account of the life and teaching and in defence of his master Socrates; the "Helenica," in seven books, being an account of 49 years of Grecian history in continuation of Thucydides to the battle of Mantinea; and "Cyropædeia," in eight books, being an ideal account of the education of Cyrus the Elder. Xenophon wrote pure Greek in a plain, perspicuous, and unaffected style, had an eye to the practical in his estimate of things, and professed a sincere belief in a divine government of the world (435-354 B.C.).
[Xeres] (61), a town in Spain, 14 m. NE. of Cadiz, a well-built, busy town, and the centre of the trade in sherry wine, which takes its name from it, and of which there are large stores.
[Xerxes], a king of Persia, son of Darius I., whom he succeeded on the throne in 485 B.C.; in his ambition to subdue Greece, which, after suppressing a revolt in Egypt, he in 481 essayed to do with an immense horde of men both by sea and land, he with his army crossed the Hellespont by means of a bridge of boats, was checked for a time at Thermopylæ by Leonidas and his five hundred, advanced to Athens to see his fleet destroyed at Salamis by Themistocles, fled at the sight by the way he came, and left Mardonius with 300,000 men to carry out his purpose, but, as it happened, to suffer defeat on the fatal field of Platæa in 479, and the utter annihilation of all his hopes; the rest of his life he spent in obscurity, and he was assassinated in 465 by Artabanus, the captain of his bodyguard, after a reign of 20 years.
[Xesibeland], a region in South Africa lying between Griqualand East and Pondoland; was annexed to Cape Colony in 1886.
[Ximenes de Cisneros, Francisco], cardinal and statesman, born in Castile, of a poor but noble family; studied at Salamanca and went to Rome, where he gained favour with the Pope, who appointed him to the first vacant ecclesiastical preferment in Spain, as the result of which he in 1495 became archbishop of Toledo, but not till he was 60 years of age; in 10 years after this he became regent of Spain, and conducted the affairs of the kingdom with consummate ability. He was a severe man, and he was careful to promote what he considered the best and highest interests of the nation; but he was narrow-minded, and did often more harm than good; he was intolerant of heresy such as the Church deemed it to be, and contrived by his policy to confer more than sovereign rights upon the crown. He was to Spain pretty much what Richelieu was to France.
