whereas, if the long syllables come first the foot is called a palimbacchius. Three shorts make a trochee, although those who give that name to the choreus call it a tribrach: three longs make a molossus.
Every one of these feet is employed in prose, but those which take a greater time to utter and derive a certain stability from the length of their syllables produce a weightier style, short syllables being best adapted for a nimble and rapid style. Both types are useful in their proper place: for weight and slowness are rightly condemned in passages where speed is required, as are jerkiness and excessive speed in passages which call for weight.
It may also be important to remark that there are degrees of length in long syllables and of shortness in short. Consequently, although syllables may be thought never to involve more than two time-beats or less than one, and although for that reason in metre all shorts and all longs are regarded as equal to other shorts and longs, they none the less possess some undefinable and secret quality, which makes some seem longer and others shorter than the normal. Verse, on the other hand, has its own peculiar features, and consequently some syllables may be either long or short.
Indeed, since strict law allows a vowel to be long or short, as the case may be, when it stands alone, no less than when one or
For both a and gres are short, but the latter lengthens the former, thereby transferring to it something of its own time-length. But how can it do this, unless it possesses greater length than is the portion of the shortest syllables, to which it would itself belong if the consonants st were removed? As it is, it lends one time-length to the preceding syllable, and subtracts one from that which follows. [*]( This theory involves the allotment of a time-value to consonants: gres gives the time-value of gr to a, and itself borrows an equivalent time-value from st. This view is more explicitly expressed by the fifth-century grammarian Pompeius (112. 26k), who allots the value of half a time-length to each consonant. Therefore to ă (= one time-length) are added the two half time-lengths represented by gr (see Lindsay, Lat. Language, p. 129). ) Thus two syllables which are naturally short have their time-value doubled by position.
