Czech painter Emil Filla created the cycle “Slovak Folk Songs” – almost thirty large paintings - towards the end of his life, from 1948 to 1951. Most of them are property of the Benedikt Rejt Gallery. The paintings cover the topic of Slovakian folk songs using Chinese ink painting techniques. The topic of rebellion and sadness and the expressivity of the technique used was not appreciated by members of III. Krajské středisko Svazu československých výtvarných umělců (The Third Regional Centre of the Union of the Czechoslovak Visual Artists). In 1951, they forbid the exhibition of these paintings. The meeting of this committee is called the Filla Trial and illustrates the values of official artists in the 1950s.
