Based on the verse-theoretical literature, the free verse of Tonko Maroević is analyzed. The first part of the paper deals with a concise presentation of scientific descriptions of free verse, which serves as the basis for the analysis of free verse by Tonko Maroević. Then, in the following chapters, Maroević's poetics is presented, as well as its important determinants such as textuality as a specific of his poetry (metatextuality, intertextuality and intermediality, and metametricity). The central part of the paper is devoted to the analysis of Maroević's free verse, namely, the rhythmic, graphic (strophic) and euphonic structure of verse are analyzed. The analysis shows which metric properties cause a kind of rhythmic constriction and when the free verse is being released of certain metric constants that visually, but also audibly, burdened the rhythmic structure of the poem itself. Also, the type of free verse (ghost of meter), to which the bound verse is a metametric background, is shown. The concluding section presents the types and subtypes of free verse that have crystallized by this analysis.
