Prehistory of The Saturnian
A large number of the verses have a 4 || 3 || 3 || 3 syllable count and division, which scholars have been inclined to take as underlying or ideal. This has permitted comparison with meters from related Indo-European poetic traditions outside Italic, such as Celtic, and a few scholars have tried to trace the verse back to Proto-Indo-European. John Vigorita derived the 4 || 3 || 5-6 syllable Saturnian from:
a Proto-Indo-European 7- or 8-syllable line combined with a shorter 5- or 6-syllable line, which is itself derivable from the octosyllable by undoing truncations (noted in metrical schemes by one or more ^'s, wherever in the meter the truncation has occurred).
M.L. West schematized this subset of verses as:
which he then traces to two Proto-Indo-European octosyllables:
one giving the Saturnian's heptasyllabic half-line by acephaly (truncation of line-beginning), the other yielding the hexasyllabic colon both by acephaly and catalexis (truncation of line-end). Ultimately, owing to the difficulties of describing and analyzing the Saturnian without taking its history into account, attempts at reconstruction have not won acceptance.
