THE LENGTHENING OF SHORT FINAL SYLLABLES IN VIRGIL

On occasions, Virgil permits himself a certain licence in his metrication, when he lengthens syllables at the end of words which would normally be short both by nature and by position. Ancient authorities commentating on these irregularities explain them either by focusing on their position in the verse, or by suggesting that Virgil's usage in these instances reflects that these syllables had been long in quantity in earlier periods of Latin poetry. With regard to the first of these tentative explanations, it is indeed the case that in all the instances where Virgil permits himself this licence, the syllables which are lengthened in this way are in arsis, that is, they fall on the last syllable of words which occur in the first part of the foot, and therefore coincide with the ictus, or the metrical beat. 

45 instances of this irregular lengthening of short final syllables are found in Virgil's works. These are divided below into certain groupings, most of which reflect different parts of speech or letter endings. In each case the whole verse is shown, and the affected syllable is underlined.

Conclusion. It can be seen clearly from the above instances that Virgil never allows himself the licence to lengthen a vowel that would normally be short unless the word concerned is in arsis, and, indeed, seldom where the lengthened syllable is not immediately followed by a main caesura, i.e. a slight break in the line. Of the above instances, it is only in 7 cases that the lengthened syllable is not followed by the main caesura. These are the first four, where it could not be applicable in any case; and D. i. g; E. i. b, and F. i. So in the overwhelming majority of cases the lengthening of a final short syllable only occurs when the word concerned is in arsis and comes immediately before the line's main caesura. Another possibly relevant factor is that in the case of 17 of the above instances the short syllable ends in 'r'. If 'r' is considered as a trilled consonant, it can be 'dwelt upon' in pronunciation, so as to lengthen the preceding vowel.
