=Cic´ero, M. T.=, born at Arpinum, was son of a Roman knight and lineally descended from the ancient kings of the Sabines. In youth he displayed many abilities, and was taught philosophy by Philo, and law by Mutius Scævola. He applied himself with great diligence to the study of oratory, and was distinguished above all the speakers of his time in the Roman forum. He signalized himself in opposing Catiline, whom he publicly accused of treason against the State, and whom he drove from the city. After a number of vicissitudes of fortune he was assassinated, B.C. 43, at the age of sixty-three. =Cincinna´tus, L. Q.= A celebrated Roman, who was informed, as he plowed in the fields, that the senate had chosen him to be dictator. On this he left the plow and repaired to the field of battle, where his countrymen were opposed by the Volsci and Æqui. He conquered the enemy, and entered Rome in triumph. =Cir´ce.= A daughter of Sol and Perseis, celebrated for her knowledge of magic and venomous herbs. She was carried by her father to an island called Æaea. Ulysses, on his return from the Trojan war, visited her coasts, and his companions were changed, by her potions, into swine. Ulysses, who was fortified against enchantments by an herb which he had received from Mercury, demanded of Circe the restoration of his companions to their former shape; she complied with his wishes, and eventually permitted him to depart from her island. =Claudia´nus.= A celebrated poet, in the age of Honorius, who is considered by some writers to equal Virgil in the majestic character of his style. =Clau´dius, T. Drusus Nero=, son of Drusus, became emperor of Rome after the death of Caligula. He went to Britain, and obtained a triumph for victories achieved by his generals. He suffered himself to be governed by favorites, whose avarice plundered the State and distracted the provinces. He was poisoned by Agrippina, who wished to raise her son Nero to the throne. =Cleopa´tra=, queen of Egypt, daughter of Ptolemy Auletes, was celebrated for her beauty. Antony became enamored of her and married her, ignoring his connection with Octavia, the sister of Augustus. He gave her the greatest part of the eastern provinces of the Roman empire. This caused a rupture between Augustus and Antony, and these two famous men met at Actium, when Cleopatra, by flying with sixty ships, ruined the battle for Antony, and he was defeated. Cleopatra destroyed herself by applying an asp to her breast. =Cli´o.= The first of the Muses, daughter of Jupiter and Mnemosyne. She presided over history. =Cloaci´na.= A goddess at Rome who presided over the Cloacæ, which were large receptacles for the filth of the whole city. =Clo´tho=, the youngest of the three Parcæ, who were daughters of Jupiter and Themis, was supposed to preside over the moment of birth. She held the distaff in her hand and spun the thread of life.
