Naïve, or primitive art is a distinct segment of the art of the 20th century. In Croatia, naïve art was at first connected with the works of peasants and working men, ordinary men and women, of whom the most successful, over the course of time, became professional artists. Naïve art assumes the work of artists who are more or less self-taught, painters and sculptors with no formal art training, but who have achieved their own creative style and a high level of art. An identifiably individual style and poetic nature distinguishes the Naïve from other "amateur" painters and sculptors, and from the general self-taught artist. The view of a Naïve artist will usually display unusual proportions and perspective, and certain illogicalities of form and space. Such characteristics are the expression of a free creative imagination, in a similar way to other 20th-century art movements such as Symbolism, Expressionism, Cubism, and Surrealism.
