CLAUDIUS. CLAUSEWITZ. to WniuUbcck, whore lie lienoefoitli lived. H«y ^as appointed in 1778 auditor of tlie prtivincial bauk of -Vltona, by the Crown Prinee Frederick of Denmark, who also, in 1785. granted liini a bniall annuity. His collected works, published in 177.3-1812 (eight parts), with the (|uaint title Asiniis Omnia Sua .S'tci/m Porlanif, were in great part taken from his contributions to the M'andsbcckcr Bute. His prose is shrewd, apho- ristic, with a certain naive humor; his verse, now buoyantly merry, now patriotic, now in the best .sense religious, is ahvay.s fresh, simple, and sin- cere. Many of his lyrics, such as Dcr Mond ist aufyeynnyen and the RhcimceinUed ('Bekriinzt niit Laub"), have continued to be popular favor- ites throughout Germany. He also translated into German Fenclon and other writers, French and Englisli. The collected works have been ex- cellently edited by Redlich ( 12th ed., Gotha, 1882), For his biography, consult Herbst (Gotha. 1878) and Gcrok (Darmstadt, 1881). CLAUDIUS C^'CUS, Appirs. A Roman pa- trician of the fourth and third centuries B.C. When censor, in u.o. 312, he gained many ad- herents by invading the traditional rights of the patricians, and admitting men of low birth to senatorial rank ; but liis nominations were quickly set aside. He is more memorable for having at the same time undertaken the construction of the sreat Appian Way from Rome to Capua, and also of the fir.st aqueduct (Aqua Appia) to bring a supply of water into the city. In order to complete these works, he arbitrarily continued his censorship beyond the legal limits. He was elected consul in n.c. ,307 and 296, and met with sviccess in several campaigns against the Samnites and Etruscans. When Pyrrhus of Epirus sent Cineas to Rome with terms of peace unfavorable to Roman greatness, it was only the eloquence of the aged Claudius that prevented the Senate from accepting them. In his old age Claudius is said to have become blind, whence his cognomen, 'Csecus,' He was the author of works in both prose and verse, of which almost nothing is known.

He was one of the most radical iconoclasts of his time, and protested against the use of images, the invocation of saints, and the veneratitin of relies. His attitude kept him in constant con- troversy with Pope Paschal I. Claudius wrote an Apologeticuin. directed against the Abbot Theode- mir, of the Convent of Psalmody, near Ximes. The abbot's part was taken by Dungall. an Irish scholar and teacher, who called upon the King to "crush the tail of the serpent in Claudius, as Charlemagne had so well crushed the head in his master, Felix of Urgel." Jonas of Orleans, at the request of the Kniperor, also wrote against Claudius, but both Louis and Claudius died be- fore the publication of his work.
