This dissertation on the Additional Short Syllables in Ovid was suggested by a statement made by Dr. John F. Gummere in his dissertation, that a very convenient way to get a short syllable in place of a long one was to substitute the plural for the singular in the nominative and accusative cases of neuter nouns. He refers to the figures of R. B. Steele, who has shown that fifteen Latin poets have an average of 45 per cent of dactyls in the first four feet of their hexameter, that Ovid has 54.6 per cent of dactyls in his Metamorphoses, and that Vergil has 44.1 per cent of dactyls in his Aeneid. It will be seen that Ovid gained over Vergil 84 short syllables per 100 lines. In Chapter IV it will be seen that in five books of the Metamorphoses and three books of the Aeneid Ovid gained over Vergil 84.6 short syllables per 100 lines. This figure will therefore be used throughout this dissertation. Vergil's percentage has been chosen for comparison with Ovid's, first, because it is so near the average, and second, because Dr. Gummere's figures for the neuter plural in Vergil are available.
