In this work are exploring grotesque elements in the plays of Mate Matišić and Ivo Brešan. Selected dramas (Angels of Babylon, Priest's children, Hydroelectric power station in Suhi dol, Vision of Jesus Christ in barrack V. P. 2507) are modern Croatian dramas and because of that fact in the first part of work will be presented various theories of grotesque, than something about the notion of grotesque in art, especially in modern Croatian drama in 1960s (at the theatre scene) and 1970s (in written drama), as well as their connection. Beside mentioned, indispensable and at the same time fundamental parts of this paper are examples of grotesque elements (grotesque situations, characters, language) on the bases of which we can notice similarities and differences in the use of grotesque by Matišić and Brešan. While in Brešan's work grotesque is a result of compound of tragic and comical (when you consider the fact that is difficult to distinguish between one and the other elements), carnivalization, caricatural elements and distortions, in Matišić's dramas elements of comedy gradually exceed into the grotesque. However, different ways of achieving grotesque by these two authors lead to the same result, pervasion their plays with grotesque elements (characters, situation, language), thanks to which situations that can be noticed in everyday life are additionally clarified, but in the dramas they are filled with distortions and caricatural elements.
