The _classicum_, which originally meant a signal, rather than the musical instrument which gave the signal, was usually sounded with the _cornu_. “Sonuit reflexo classicum cornu, Lituusque _adunco_ stridulos cantus Elisit aere.” (Sen. _Oed._ 734.) The _Cornicines_ 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. [Illustration: Corona Civica, on a Coin of the Emperor Galba. SPQR OB CS = Senatus Populusque Romanus ob civem servatum.] CŎRŌNA (στέφανος), a crown, that is, a circular ornament of metal, leaves, or flowers, worn by the ancients round the head or neck, and used as a festive as well as funereal decoration, and as a reward of talent, military or naval prowess, and civil worth. Its first introduction as an honorary reward is attributable to the athletic games, in some of which it was bestowed as a prize upon the victor. It was the only reward contended for by the Spartans in their gymnic contests, and was worn by them when going to battle. The Romans refined upon the practice of the Greeks, and invented a great variety of crowns formed of different materials, each with a separate appellation, and appropriated to a particular purpose.--I. CORONA OBSIDIONALIS. Amongst the honorary crowns bestowed by the Romans for military achievements, the most difficult of attainment, and the one which conferred the highest honour, was the _corona obsidionalis_, presented by a beleaguered army after its liberation to the general who broke up the siege. It was made of grass, or weeds and wild flowers, thence called _corona graminea_, and _graminea obsidionalis_, gathered from the spot on which the beleaguered army had been enclosed.--II. CORONA CIVICA, the second in honour and importance, was presented to the soldier who had preserved the life of a Roman citizen in battle. It was made of the leaves of the oak. The soldier who had acquired this crown had a place reserved next to the senate at all the public spectacles; and they, as well as the rest of the company, rose up upon his entrance. He was freed from all public burthens, as were also his father, and his paternal grandfather; and the person who owed his life to him was bound, ever after, to cherish his preserver as a parent, and afford him all such offices as were due from a son to his father.--III. CORONA NAVALIS or ROSTRATA, called also CLASSICA. It is difficult to determine whether these were two distinct crowns, or only two denominations for the same one. It seems probable that the _navalis corona_, besides being a generic term, was inferior in dignity to the latter, and given to the sailor who first boarded an enemy’s ship; whereas the _rostrata_ was given to a commander who destroyed the whole fleet, or gained
