[Celsius], a distinguished Swedish astronomer, born at Upsala, and professor of Astronomy there; inventor of the Centigrade thermometer (1701-1744).
[Celsus], a celebrated Roman physician of the age of Augustus, and perhaps later; famed as the author of "De Medicina," a work often referred to, and valuable as one of the sources of our knowledge of the medicine of the ancients.
[Celsus], a philosopher of the 2nd century, and notable as the first assailant on philosophic grounds of the Christian religion, particularly as regards the power it claims to deliver from the evil that is inherent in human nature, inseparable from it, and implanted in it not by God, but some inferior being remote from Him; the book in which he attacked Christianity is no longer extant, only quotations from it scattered over the pages of the defence of Origen in reply.
[Celtibe`ri], an ancient Spanish race occupying the centre of the peninsula, sprung from a blending of the aborigines and the Celts, who invaded the country; a brave race, divided into four tribes; distinguished in war both as cavalry and infantry, and whom the Romans had much trouble in subduing.
[Celts]. The W. of Europe was in prehistoric times subjected to two invasions of Aryan tribes, all of whom are now referred to as Celts. The earlier invaders were Goidels or Gaels; they conquered the Ivernian and Iberian peoples of ancient Gaul, Britain, and Ireland; their successors, the Brythons or Britons pouring from the E., drove them to the westernmost borders of these countries, and there compelled them to make common cause with the surviving Iberians in resistance; in the eastern parts of the conquered territories they formed the bulk of the population, in the W. they were in a dominant minority; study of languages in the British Isles leads to the conclusion that the Irish, Manx, and Scottish Celts belonged chiefly to the earlier immigration, while the Welsh and Cornish represent the latter; the true Celtic type is tall, red or fair, and blue-eyed, while the short, swarthy type, so long considered Celtic, is now held to represent the original Iberian races.
[Cenci, The], a Roman family celebrated for their crimes and misfortunes as well as their wealth. Francesco Cenci was twice married, had had twelve children by his first wife, whom he treated cruelly; after his second marriage cruelly treated the children of his first wife, but conceived a criminal passion for the youngest of them, a beautiful girl named Beatrice, whom he outraged, upon which, being unable to bring him to justice, she, along with her stepmother and a brother, hired two assassins to murder him; the crime was found out, and all three were beheaded (1599); this is the story on which Shelley founded his tragedy, but it is now discredited.
[Cenis, Mont], one of the Cottian Alps, over which Napoleon constructed a pass 6884 ft. high in 1802-10, through which a tunnel 7½ m. long passes from Modane to Bardonnêche, connecting France with Italy; the construction of this tunnel cost £3,000,000, and Napoleon's pass a tenth of the sum.
[Censors], two magistrates of ancient Rome, who held office at first for five years and then eighteen months, whose duty it was to keep a register of the citizens, guard the public morals, collect the public revenue, and superintend the public property.
[Cen`taurs], a savage race living between Pelion and Ossa, in Thessaly, and conceived of at length by Pindar as half men and half horses, treated as embodying the relation between the spiritual and the animal in man and nature, in all of whom the animal prevails over the spiritual except in Chiron, who therefore figures as the trainer of the heroes of Greece; in the mythology they figure as the progeny of Centaurus, son of [Ixion] (q. v.) and the cloud, their mothers being mares.
[Central America] (3,000), territory of fertile tableland sloping gradually to both oceans, occupied chiefly by a number of small republics, lying between Tehuantepec and Panama in N. America; it includes the republics of Guatemala, Honduras, St. Salvador, Nicaragua, and Costa Rica, and a few adjoining fractions of territory.
