This book is the most extensive study to date of the metric form and rhythmic function of a modern Greek poetic text, specifically the Odes of Andreas Kalvos. The author challenges the view that the Greek kalvian metric originates from the fifteen-syllable verse, proving that the origins of the poetic forms that make up the Odes are Italian and establishes that the rhythmic result of Greek kalvian poetry, its multifaceted harmony, is the complex product of the synergy of Greek and Italian rhythmic elements. This synergy leads to the unique and unparalleled rhythmic-expressive result that is primarily responsible for the aesthetic vitality of the Odes today. The metric analysis of the Odes culminates in a comprehensive proposal for interpreting their rhythm and, more generally, their poetic function. The issue of the origin of the metric system of the Odes and their rhythmic identity - one of the most burning and thorny problems in Greek metrical research - seems to find its definitive resolution.
