What are your opinons about scansion of Saturnian poetry?
I am tempted to suggest:
Accentual, but count of syllables, or count of morae, mattered.
Stress accent on the first syllables of words as in Old Latin.
Usually 5, sometimes 4, stressed syllables placed at about equal time intervals through the line.
Each line is somewhere around 20 morae, plus or minus a few.
Not certain whether Saturnian poetry elided like in classical meters imitated from Greek.
Tendency for stressed syllables in the same line to alliterate, but not as rigidly as in Germanic poetry: see
If Saturnian verse was accentual by the Old Latin initial accent, that would explain why Saturnian verse was mostly forgotten, as it would no longer scan properly when read out with the well-known classically-placed accent.
Saturnian poetry may have been designed to be sung to some sort of music with a strong regular rhythm.
