CA'CUS, a giant who lived in a cave on mount Av'entine (3 _syl_.). When Herculês came to Italy with the oxen which he had taken from Ger'yon of Spain, Cacus stole part of the herd, but dragged the animals by their tails into his cave, that it might be supposed they had come _out_ of it. If he falls into slips, it is equally clear they were introduced by him on purpose to confuse like Caeus, the traces of his retreat.--_Encyc. Brit_. Art. "Romance." CAD, a low-born, vulgar fellow. A cadie in Scotland was a carrier of a sedan-chair. All Edinburgh men and boys know that when sedan-chairs were discontinued, the old cadies sank into ruinous poverty, and became synonymous with roughs. The word was brought to London by James Hannay, who frequently used it.--M. Pringle. [Illustration] M. Pringle assures us that the word came from Turkey. CADE (_Jack_), Irish insurgent in reign of Henry VII. Assuming the name of Mortimer, he led a company of rebels from Kent, defeated the king's army, and entered London. His short-lived triumph was ended by his death at Lewes. He appears in _Henry VI._ by Shakespeare. CADE´NUS (3 _syl._) dean Swift. The word is simply _de-ca-nus_ ("a dean"), with the first two syllables transposed (_ca-de-nus_). Vanessa is Miss Esther Vanhomrigh, a young lady who fell in love with Swift, and proposed marriage. The dean's reply is given in the poem entitled _Cadenus and Vanessa_ [_i.e._ Van-Esther]. CADUCEUS meant generally a herald's staff; as an emblem of a peaceful errand it was made of a branch of olive-wood with the twigs, which, later, were transformed to serpents. In this form it is associated with Mercury, the herald and messenger of the gods--that "beautiful golden rod with which he both puts men to sleep and wakens them from slumber." Homer, _Odyssey_, xxiv. CADUR´CI, the people of Aquita´nia. CAD´WAL. Arvir´agus, son of Cym´beline, was so called while he lived in the woods with Bela´rius, who called himself Morgan, and whom Cadwal supposed to be his father.--Shakespeare, _Cymbeline_ (1605). CADWALLADER, called by Bede (1 _syl._) Elidwalda, son of Cadwalla king of Wales. Being compelled by pestilence and famine to leave Britain, he went to Armorica. After the plague ceased he went to Rome, where, in 689, he was baptized, and received the name of Peter, but died very soon afterwards. Cadwallader that drave [_sailed_] to the Armoric shore. Drayton, _Polyolbion_, ix. (1612). _Cadwallader_, the misanthrope in Smollett's _Peregrine Pickle_ (1751). _Cadwallader_ (_Mrs_.), character in _Middle-march_, by George Eliot. CADWALL'ON, son of the blinded Cyne'tha. Both father and son accompanied prince Madoc to North America in the twelfth century.--Southey, _Madoc_ (1805). _Cadwal'lon_, the favorite bard of prince Gwenwyn. He entered the service of sir Hugo de Lacy, disguised, under the assumed name of Renault Vidal.--Sir W. Scott, _The Betrothed_ (time, Henry II.).
