CORNU

a wind instrument, anciently made of horn, but afterwards of bra . Like the tuba , it differed from the tibia in being a larger and more powerful instrument, and from the tuba itself, in being curved nearly in the shape of a C, with a cro -piece to steady the instrument for the convenience of the performer. Hence Ovid says ( Met. i. 98): “Non tuba direct i , non aeris cornua flex i .” The cla i cum , which originally meant a signal, rather than the musical instrument which gave the signal, was usually sounded with the cornu . “Sonuit reflexo cla i cum cornu, Lituus que adunco stridulos cantus Elisit aere.” (Sen. Oed. 734.) The Corni cines and Liticines , the persons who blew the Cornu and Lituus , formed a collegium. In the preceding cut, M. Julius Victor, a member of the Collegium, holds a lituus in his right hand, and touches with his left a cornu on the ground. See engraving under Tuba .
