An example of the oldest Latin extant is contained in the sacred chant of the Fratres Arvales. These were a college of priests, whose function was to offer prayers for plenteous harvests, in solemn dances and processions at the opening of spring. Their song was chanted in the temple with closed doors, accompanied by that peculiar dance which was termed the tripudium, from its containing three beats. The inscription which embodied this litany was discovered in Rome in 1778 A.D. The monument belongs to the reign of Heliogabalus, 218 A.D., but although the date is so recent, the permanence of religious formulas renders it probable that the inscription contains the exact words sung by this priesthood in the earliest times. The "Carmen Saliare," or the Salian hymn, the _leges regiae_, the Tiburtine inscription, the inscription on the sarcophagus of L. Cornelius Scipio Barbatus, the great-grandfather of the conqueror of Hannibal, the epitaph of Lucius Scipio, his son, and, above all, the Twelve Tables, are the other principal extant monuments of ancient Latin. The laws of the Twelve Tables were engraven on tablets of brass, and publicly set up in the comitium; they were first made public 449 B.C. Most of these literary monuments were written in Saturnian verse, the oldest measure used by the Latin poets. It was probably derived from the Etruscans, and until Ennius introduced the heroic hexameter, the strains of the Italian bards flowed in this metre. The structure of the Saturnian is very simple, and its rhythmical arrangement is found in the poetry of every age and country. Macaulay adduces, as an example of this measure, the following line from the well-known nursery song,---- "The queén was ín her párlor, | eáting breád and hóney." From this species of verse, which probably prevailed among the natives of Provence (the Roman Provincia), and into which, at a later period, rhyme was introduced as an embellishment, the Troubadours derived the metre of their ballad poetry, and thence introduced it into the rest of Europe.
