Some important phenomena of archaic Latin metrics, which in the tradition of philological
studies are called correptio iambica and the rules of Ritschl, Hermann – Lachmann and Fraenkel –
Thierfelder – Skutsch, for the first time receive a unified explanation. The metrical theory is independently motivated, because it is based on the rhythmical structure of the Latin language, and the restrictions on the formation of the so-called ‘phonological foot’ are the same that play a crucial role for the placement of Latin accent.
