In Antun Bratosaljić Sasin's texts, a write of the post-Renaissance period, one notices an aberration in the quantative presence of octosyllabic verses and double- rhymed alexandrines if compared to the Renaissance tradition. As is the custom with Renaissance writers, the double-rhymed alexandrine does not dominate but Sasin frequently resorts to octosyllabic verse. The use of octosyllabic verse is not accidental bin is conditioned in respect to genre which points to new developments in literature, one of which is the loss of the dominant position of an ingruined type of verse. What we have here is the influence of a new poetics which is confirmed by the metrical situation in his pastorals, where the most important novelty is the use of the intermezzo and the introduction of octosyllabic verse as an equally valid form of expression for dramatic texts in certain dramatic situations. The metrical semantics of Sasin's pastorals represents a deviation from Renaissance poetics and points the way to new literary procedures that would receive their full affirmation in the Baroque period.
