CINNA, a tragedy by Pierre Corneille (1637). Mdlle. Rachel, in 1838, took the part of Emilie the heroine, and made a great sensation in Paris. CINQ-MARS, (_H. Coiffier de Ruze, marquis de_), favorite of Louis XIII. and _protégé_ of Richelieu (1620-1642). Irritated by the cardinal's opposition to his marriage with Marie de Gonzague, Cinq-Mars tried to overthrow or to assassinate him. Gaston, the king's brother, sided with the conspirator, but Richelieu discovered the plot, and Cinq-Mars, being arrested, was condemned to death. Alfred de Vigny published, in 1826, a novel (in imitation of Scott's historical novels) on the subject, under the title of _Cinq-Mars._ CINQUECENTO (3 _syl_.), the fifteenth century of Italian notables. They were Ariosto (1474-1533), Tasso (1544-1595), and Giovanni Rucellai (1475-1526), _poets_; Raphael (1483-1520), Titian (1480-1576), and Michael Angelo (1474-1564), _painters_. These, with Machiavelli, Luigi Alamanni, Bernardo Baldi, etc., make up what is termed the "Cinquecentesti." The word means the worthies of the '500 epoch, and it will be observed that they all flourished between 1500 and the close of that century. (See SEICENTA). Ouida writes in winter mornings at a Venetian writing-table of cinquecento work that would enrapture the souls of the virtuosi who haunt Christie's.--E. Yates, _Celebrities_, xix. CIPAN'GO OR ZIPANGO, a marvellous island described in the _Voyages_ of Marco Polo, the Venetian traveller. He described it as lying some 1500 miles from land. This island was an object of diligent search with Columbus and other early navigators, but belongs to that wonderful chart which contains the _El Dorado_ of Sir Walter Raleigh, the _Utopia_ of Sir Thomas More, the _Atlantis_ of Lord Bacon, the _Laputa_ of Dean Swift, and other places better known in story than in geography. CIRCE (2 _syl_.), a sorceress who metamorphosed the companions of Ulysses into swine. Ulysses resisted the enchantment by means of the herb _moly_, given him by Mercury. Who knows not Circe, The daughter of the sun, whose charmed cup Whoever tasted lost his upright shape, And downward fell into a grovelling swine? Milton, _Comus_ (1634). CIRCUIT _(Serjeant)_, in Foote's farce called _The Lame Lover_.
