34. These early poets in the modern languages chiefly borrowed their forms of versification from the Latin. It is unnecessary to say, that metrical composition in that language, as in Greek, was an arrangement of verses corresponding by equal or equivalent feet; all syllables being presumed to fall under a known division of long and short, the former passing for strictly the double of the latter in quantity of time. By this law of pronunciation all verse was measured; and to this not only actors, who were assisted by an accompaniment, but the orators also endeavoured to conform. But the accented, or, if we choose rather to call them so, emphatic syllables, being regulated by a very different though uniform law, the uninstructed people, especially in the decline of Latinity, pronounced, as we now do, with little or no regard to the metrical quantity of syllables, but according to their accentual value. And this gave rise to the popular or rhythmical poetry of the lower empire; traces of which may be found in the second century, and even much earlier, but of which we have abundant proofs after the age of Constantine.[58] All metre, as Augustin says, was rhythm, but all rhythm was not metre: in rhythmical verse, neither the quantity of syllables, that is, the time allotted to each by metrical rule, nor even, in some degree, their number, was regarded, so long as a cadence was retained in which the ear could recognise a certain approach to uniformity. Much popular poetry, both religious and profane, and the public hymns of the church, were written in this manner; the distinction of long and short syllables, even while Latin remained a living tongue, was lost in speech, and required study to attain it. The accent or emphasis, both of which are probably, to a certain extent, connected with quantity and with each other, supplied its place; the accented syllable being, perhaps, generally lengthened in ordinary speech; though this is not the sole cause of length, for no want of emphasis or lowness of tone can render a syllable of many letters short. Thus we find two species of Latin verse: one metrical, which Prudentius, Fortunatus, and others aspired to write; the other rhythmical, somewhat licentious in number of syllables, and wholly accentual in its pronunciation. But this kind was founded on the former, and imitated the ancient syllabic arrangements. Thus the trochaic, or line, in which the stress falls on the uneven syllables, commonly alternating by eight and seven, a very popular metre from its spirited flow, was adopted in military songs, such as that already mentioned of the Italian soldiers in the ninth century. It was also common in religious chants. The line of eight syllables, or dimeter iambic, in which the cadence falls on the even places, was still more frequent in ecclesiastical verse. But these are the most ordinary forms of versification in the early French or Provençal, Spanish, and Italian languages.
