When a short syllable is followed by a long the effect is one of vigorous ascent, while a long followed by a short produces a gentler impression and suggests descent. It is therefore best to begin with long syllables, though at times it may be correct to begin with short, as in the phrase novum crimen: [*](pro Lig. i. 1. ) a gentler effect is created, if we commence with two shorts, as in the phrase animadverti iudices: but this opening, which comes from the pro Cluentio, is perfectly correct, since that speech begins with something similar to partition, which requires speed. [*](pro Cluent. i. 1. The speech begins: I note, gentlemen of the jury, that the whole speech of the accuser falls into two parts, of which one, etc. It is this which is described as similar to partition. lenius a dabaas Capperonnier for levibus (AG). )

Similarly the conclusion of a sentence is stronger when long syllables preponderate, but it may also be formed of short syllables, although the quantity of the final syllable is regarded as indifferent. I am aware that a concluding short syllable is usually regarded as equivalent to a long, because the time-length which it lacks appears to be supplied from that which follows. But when I consult my own ears I find that it makes a great difference whether the final syllable is really long or only treated as the equivalent of a long. For there is not the same fullness of rhythm in diccre incipieniem timere [*]( pro Mil. i. 1. To show fear when beginning to speak. ) as there is in ausus est confiteri. [*](pro Lig. i. 1. )

But if it makes no difference whether the final syllable be long or short, the concluding feet in these two instances must be identical: and yet somehow or other one gives the impression of sitting down and the other of a simple halt. This fact has led some critics to allow three timebeats for a final long syllable, adding the extra

It is not, however, necessary to go back further than three feet, and only that if the feet contain less than three syllables, for we must avoid the exactitude of verse: on the other hand, we must not go back less than two: otherwise we shall be dealing with a foot and not with rhythm. But in this connexion the dichoreus may be regarded as one foot, if indeed a foot consisting of two chorei can be considered as a single foot.

The same is true of the paean composed of the choreus and a pyrrhic, a foot which is regarded as specially suitable to the beginning of a sentence, or of the other paean, formed of three shorts followed by a long, to which the conclusion is specially dedicated. It is of these two forms that writers on rhythm generally speak. Some, however, call all feet containing three short syllables and a long by the name of paean, irrespective of the position of the long syllable, and merely taking into account the total number of time-lengths that it contains.
