=Isoc´rates.= A celebrated orator, son of a musical instrument maker at Athens. He opened a school of eloquence at Athens, where he was distinguished for the number, character, and fame of his pupils. He was intimate with Philip of Macedon, but the aspiring ambition of Philip displeased Isocrates, and the defeat of the Athenians at Chæronea had such an effect on him that he did not long survive it. He died, after being four days without taking any aliment, in his ninety-ninth year, about 338 years B.C. He was honored after death by the erection of a brazen statue to his memory by Timotheus, one of his pupils, and Aphareus, his adopted son. Milton, in one of his sonnets, speaks of him as "that old man eloquent" when alluding to his death as being caused by the news of the battle of Chæronea. =I´tys.= A son of Tereus, king of Thrace, and Procne, daughter of Pandion, king of Athens. He was killed by his mother when he was six years old, and served up to his father to be eaten by him. He was changed into a pheasant, his mother into a swallow, and his father into an owl. =Ixi´on.= A king of Thessaly, son of Phlegias, or, according to Hyginus, of Leontes, or, according to Diodorus, of Antion and Perimela. Jupiter carried him to heaven and placed him at the table of the gods, where he became enamored with Juno, which so incensed Jupiter that he banished him from heaven, and ordered Mercury to tie him to a wheel in hell, which continually whirled round, keeping Ixion in perpetual torture. =Ja´nus.= An ancient king who reigned in Italy. He was a native of Thessaly, and, according to some writers, a son of Apollo. He built a town which he called Janiculum. Some authors make him to have been son of Coelus and Hecate. He is represented with two faces, because he was acquainted with the past and future. His temple was always open in time of war, and was shut when peace existed. =Jap´etus.= A son of Coelus or Titan and Terra, who married Asia, or, according to some writers, Clymene. The Greeks looked on him as the father of all mankind. =Ja´son.= A celebrated hero, son of Æson and Alcimedes. His education was entrusted to the Centaur Chiron. The greatest feat recorded of him is his voyage in the Argo to Colchis to obtain the Golden Fleece, which, aided by Juno, he succeeded in doing. Medea, daughter of Ætes, king of Colchis, fell in love with Jason. She was a powerful magician, and on Jason having vowed eternal fidelity to her, she gave him charms to protect him from danger. After securing the Fleece, Jason set sail from the country with his wife Medea. After some years he became enamored with Glauce, daughter of Creon, king of Corinth, whom he married, having divorced Medea. This cruel act was revenged by Medea, who destroyed her children in the presence of their father. Jason is said to have been killed by a beam which fell on his head as he was reposing by the side of the ship which had borne him to Colchis.
